This looks like a network glitch when downloading the artifacts or a proxy server getting into the way. Please try again. If this doesn't help, some cache might be causing this broken file to stick around, so please search for the files with those names "org.springframework.ide.eclipse.docker.client" and "org.springframework.tooling.boot.ls" and delete them from the cache. Hope that helps!

It looks like you are using an updated Eclipse version (2021-03) here, for which the latest versions of the Spring Tools 4 (on the Eclipse Marketplace) are no longer compatible with. Therefore, you are running into an issue, most likely the installation process tries to install components from a newer Eclipse platform version (alongside the Spring Tools components) that use a newer signing infrastructure - which then results in the above mentioned error.
The best solution here would be to use a more recent Eclipse platform (2022-09 at the time) and install the Spring Tools 4 on top of that Eclipse - or grab the latest ready-to-use distribution from https://spring.io/tools.
It will give you the latest version of the Spring Tools 4 that was compatible with that version of Eclipse - but it is an outdated and no longer supported version, so I don't recommend this option and would strongly recommend to use the latest version instead - if at all possible.
Just downloaded a fresh install of Eclipse Version: 2022-09 (4.25.0) - Build id: 20220908-1902, and fired up Marketplace to install Spring Tools 4 (4.16.0.RELEASE). I only kept the two required components and clicked on Install. As it's downloading, a "Trust" dialog popped up asking me to trust the expired certificates from Pivotal - the expiration dates were 2018 and 2020. Google search turned up nothing. Can I continue installation without trusting the expired certificates?
This is usually caused by some stale cache data. You can fix this by going to the Preferenes -> Install/Update -> Available Update Sites, then select the one you mentioned, and press "Reload". This usually solves the problem.
In case this doesn't help, delete the entry from the list of available update sites, restart the IDE, and add the entry back to the list. That should work as a last resort if everything else failed.
Select Spring Tools 4 (aka Spring Tool Suite 4) 4.10.0.RELEASE and hit Install
Hit Confirm button

Also tried installing STS4 IDE which worked fine but it keeps removing my Websphere Liberty node from Define New Server dialog when I right click in Servers tab > New Server > IBM > Websphere Liberty, so that is useless as well.
Note, the above urls have removed "://" because this site does not allow comments with extermal urls, also not helpful at all.
Thak you Martin. However, that stackoverlow did not help. I saw that post before I asked here and I followed it again. While I have been able to add certificate as described (making below assumptions as the explanation was not clear on that), I am still unable to install STS4 into my Eclipse 2021-03.
Following Stackoverflow link, I exported the certificate and used keytool to add it to my jdk1.8/jre/lib/security/cacerts
I even confirmed it has been added, also using keytool to list certificates

My C:/Program Files/Java has two versions jdk 1.8.0_172 and jdk-11.0.10. I did the above for jdk 1.8.0_172 as that is the jdk in my System Path variable.
And ended up with the same error as described in my original question
As the reporter of this mentioned in the comments there, the issue got resolved and was caused by some internal security settings that blocked something here.
Hey! The "add starters" menu option is indeed gone (since a few releases already), but I got replaced with a new "Add Starters" menu item that you should be, which also allows you to add starter modules from start.spring.io and even brings more goodies from start.spring.io into the IDE here, e.g. additional resources that start.spring.io would generate for you, new properties in your properties file (in case the selected modules include them), etc. Here is a user guide for this new way to add starters to your project: https://github.com/spring-projects/sts4/wiki/Add-Spring-Boot-Starters-To...
Hope that helps and that you like the new wizard!!!
Hello Martin,
Thank you for your answer.
Yes I know this procedure which you mentioned in the web link.
But I'm sorry, I prefer the old method with the 'Edit starters' option ...
When we choose 'Add starters', why in the graphical interface, you don't add an 'already selected' section in addition to the 'selected' section?
I think it's important to quickly have a graphic visual, rather than making a comparison with the xml file ...
The 2 ways can be complementary ...
Maybe it's hard to implement the code to be able to do this? ^^
your feedback on this is much appreciated. The reason why we no longer do something like a "pre-selection" is starter modules that you already have on your project is based on the latest generations of the initializr project and the way that works. When you select starter modules in there, the resulting project might not exactly contain those modules exclusively. There is logic in initializr and some of the starter modules to do more sophisticated things, like automatically adding additional other starters for you. And there is no "inverted logic" in there, which infers which starters you would need to select in order to produce the set of starters that you have. Therefore we don't really have a way to implement this "inverted logic". (This gets even more complicated if users edited their pom.xml file (in case you use Maven) manually). Therefore we decided to not implement any logic to pre-select existing starters on your project. Sorry for not being able to bring this pre-selection back. Hope you find the new wizard useful nevertheless. If you have additional suggestions, please raise them as enhancement requests here: https://github.com/spring-projects/sts4/issues.
Actually, identifying dependencies of a project is not that complicated in an IDE, since the Maven integration for Eclipse in this case already does that work for you - and that is what the pom dependency analyzer tool would do as well in case I understood this. The difficult part is to calculate the pre-selection on start.spring.io that would lead to the pom that you analyze. It is not a 1-to-1 mapping (for a good reason actually, from the project-generation perspective).
Hi, I recently downloaded Eclipse 2021-03, and installed STS4, but upon attempting to run a spring boot app, or even creating a new one, it doesn't show the Spring Boot wizard, or Run As Spring Boot App.
Hey! That sounds like an issue with the installation and the underlying bundles being maybe wired in a weird way. The best way forward would be a submit an issue at https://github.com/spring-projects/sts4/issues and tell us exactly which package of Eclipse 2021-03 you installed, which other third-party plugins you added, and how you installed the STS4 components then. I used the Eclipse JEE paclage of 2021-03 and installed STS4 from the Eclipse marketplace and that seemed to work, so we need to take a closer look at your exact setting in which you are trying to install the Spring Tools 4.
As a quick fix for you, feel free to download a ready-to-use distribution of the Spring Tools 4 for Eclipse from https://spring.io/tools. Version 4.10.0 of the Spring Tools 4 for Eclipse are a distribution built on Eclipse 2021-03, so you will get the latest in here as well.
<p>How to Install the JAR downloaded from spring.io/tools I tried to Install the JAR under Install New Software and the result is wrong:could not find jar:file:....</p>
If you want to install Spring Tools 4 into an existing Eclipse installation, you can choose the "Eclipse Marketplace..." menu entry, then search for Spring, pick the "Spring Tools 4" entry, and press the "Install" button.
The JAR file that you can download from the https://spring.io/tools page is a self-extracting full distribution of the Spring Tools 4 for Eclipse (including an Eclipse 2020-12 with pre-installed Spring Tools 4 extensions). You can download the JAR and double-click it. It will then self-extract the full distribution.
From the brief description it sounds like an installation issue or an incompatibility from under the hood somewhere. I would recommend to file an issue at https://github.com/spring-projects/sts4/issues/ and provide some detais (maybe a few steps to reproduce), and we can continue from there to find out what is going wrong there.
If you are not tied to Eclipse 2020-06, I could also recommend to download a ready-to-use distribution of the latest Eclipse release (2020-12) with all the Spring Tools 4 pre-installed from https://spring.io/tools.
Got the new Eclipse 2020-06 and installed Spring Tools 4 4.6.2.RELEASE and Spring Tools 3 Add-On for Spring Tools 4 3.9.13.CI. Now I am unable to find the Boot Dashboard in the Eclipse > Window > Show View. Is this view still available in the new ST 4 plugin for eclipse?
I just installed a fresh download of Eclipse version: 2020-06 (4.16.0) and then installed the Spring Tool Suite 4 for Eclipse (4.6.2 update e4.16) on my Windows 10.
It seems there is no Spring Boot Dashboard which was available in Eclipse 4.15.
How do I make the Spring Boot Dashboard available in Eclipse 4.16?
This plug in is crashing hanging and crashing my Eclipse as of 2020-03-27, I am running Ubuntu 18+ ( b4bit, fully updated/upgraded) as of Mar-27. This Ubuntu is running in Vmware Station inside Window 10/64bit.
I tried removing eclipse and all the dot file, creating new workspace and as soon as I add this plug in Eclipse crashed come back mainly when I want to highligh and replace a word in JAVA code. As soon as I remove the plug in and restart Eclipse, all is ok.
That sounds indeed bad. Can you pleaee file a bug at https://github.com/spring-projects/sts4/issues/ for this and tell us how to reproduce this crash? Is it really the JVM that is crashing or is it a freeze at the UI, so that the process isn't responding anymore? Is there something in the Error Log View that relates to the problem? Or is the VM itsel crashing and in case that happens, is there a JVM crash log file tha you could attach? In case the process freezes, there is a setting in the "Preferences -> General -> UI Responsiveness Monitoring" that you could turn on to capture stack traces while the UI seems to be frozen. That would be great and help us a lot to find the underlying issues.

When use JRE1.7 to run my Springboot project, it fail to start with error "Unrecognized VM option 'TieredStopAtLevel=1'" shown in the eclipse console. But if I use JRE1.8, it's working well. Unfortunately, JRE1.7 is requested in my project.
I searched settings but can't find place to remove this VM option.
This is part of some default options to speed up the exeution and launch of the Spring Boot app, but you can change that in the "Preferences -> Spring -> Boot", take a look at the "Fast Startup" section, where you can change those settings.
Submitted by James Balaji on Tue, 2020-03-17 10:28
Thanks your answer, I found the place and remove the option. However, still not working with another error when I run the application.... seems it's stil a problem of JDK. I have synchronized all configuration place in eclipse with JDK1.7.0 (such as project compiler,classpath settings, eclipse preferences etc). Spring boot version I use is 1.5.9 Release.
The error is "Could not find the main class". then I copy the command and run in the dos window, it says that:"Exception in thread "main" java.lang.UnsupportedClassVersionError: cn/com/MainApplication : Unsupported major.minor version 51.0". I know the 51.0 means the version jdk1.7, but I am using JDK1.7.
Could you give some advice? Does STS4 support JDk1.7?
STS4 in general supports implementing and running applications on top of a JDK7. You need to configure the JDK7 runtime environment in the preferences (as you probably did) and select it as the default for the JavaSE7 execution environment. Make sure it appears correctly as the entry in your project classpath containers in the packag explorer.
In addition to that you need to make sure to compile your project on a Java7 level by setting the compiler level in the Java compiler preferences for your project.
Then in the launch configuration, you should make sure that the JDK7 is used to launch the app. This "could not find main class" is usually related to some misconfigured JRE settings in the areas described above.

This problem is a bit complicated to analyze remotely, since it is not totally clear where this comes from. Here is what you could do to solve this:
go to the "Preferences -> Install/Update -> Available Update Sites", select the one for the Spring Tools 4 and press "Reload". Maybe that solves the problem already.
If not, remove that update site from the preferences and restart your IDE. Then try the install again.

I have installed STS 4.4.1 from the Eclipse (4.13 64bit) marketplace and don't see the create new project option after restarting the IDE. There were no error during installation. I have tried with JDK 11 and 13 without success.
Sorry for the late answer, somehow missed the question here. You could analyze the underlying issue by opening up the console, opne an OSGi Host Console, and type in "ss" for "short status". If there is anything showing up as "INSTALLED", something went wrong with regards to the dependency resolution of bundles. This is hard to debug and to solve. In that case, I would recommend to download a ready-to-use distribution from https://spring.io/tools and go from there. If the list of bundles shows up fine (nothing in the "INSTALLED" state), then the wizard to create a new project using Initializr (e.g.) should show up ("Spring Starter Project") in a "Spring" category.
I am using Eclipse 4.8 Photon and I want to install Spring Tools Suite. The least support version for Spring Tools Suite is 4.9 and predecessor Spring IDE max support is till 4.5 only.
How to install the STS for the eclipse versions 4.6,4.7, and 4.8?
The latest version of the Spring Tools 4 for Eclipse require Eclipse 2019-03 as the base platform. If you want to instal the old Spring Tool Suite 3 package instead into an Eclipse 4.8 platform, you could use this update site using the "Install New Software" dialog: https://download.springsource.com/release/TOOLS/update/e4.8/ - it serves the STS 3.9.7 release, which is the last one compatible with Eclipse 4.8.

This looks like a network glitch when downloading the artifacts or a proxy server getting into the way. Please try again. If this doesn't help, some cache might be causing this broken file to stick around, so please search for the files with those names "org.springframework.ide.eclipse.docker.client" and "org.springframework.tooling.boot.ls" and delete them from the cache. Hope that helps!

Re: Got error when installating progress.

It looks like you are using an updated Eclipse version (2021-03) here, for which the latest versions of the Spring Tools 4 (on the Eclipse Marketplace) are no longer compatible with. Therefore, you are running into an issue, most likely the installation process tries to install components from a newer Eclipse platform version (alongside the Spring Tools components) that use a newer signing infrastructure - which then results in the above mentioned error.
The best solution here would be to use a more recent Eclipse platform (2022-09 at the time) and install the Spring Tools 4 on top of that Eclipse - or grab the latest ready-to-use distribution from https://spring.io/tools.
If you have to use the 2021-03 Eclipse (for whatever reason), you can install an old version of the Spring Tools 4 using the "Install New Software" menu item and then this update repository: https://download.springsource.com/release/TOOLS/sts4/update/4.12.0.RELEA...
It will give you the latest version of the Spring Tools 4 that was compatible with that version of Eclipse - but it is an outdated and no longer supported version, so I don't recommend this option and would strongly recommend to use the latest version instead - if at all possible.
x509 certificate issue?
Submitted by Walter L on Sat, 2022-09-24 15:55
Just downloaded a fresh install of Eclipse Version: 2022-09 (4.25.0) - Build id: 20220908-1902, and fired up Marketplace to install Spring Tools 4 (4.16.0.RELEASE). I only kept the two required components and clicked on Install. As it's downloading, a "Trust" dialog popped up asking me to trust the expired certificates from Pivotal - the expiration dates were 2018 and 2020. Google search turned up nothing. Can I continue installation without trusting the expired certificates?

How to resolve?
Re: Error while installing Spring tool
Submitted by Martin Lippert on Tue, 2021-12-21 12:26
This is usually caused by some stale cache data. You can fix this by going to the Preferenes -> Install/Update -> Available Update Sites, then select the one you mentioned, and press "Reload". This usually solves the problem.
In case this doesn't help, delete the entry from the list of available update sites, restart the IDE, and add the entry back to the list. That should work as a last resort if everything else failed.

Hey! The "add starters" menu option is indeed gone (since a few releases already), but I got replaced with a new "Add Starters" menu item that you should be, which also allows you to add starter modules from start.spring.io and even brings more goodies from start.spring.io into the IDE here, e.g. additional resources that start.spring.io would generate for you, new properties in your properties file (in case the selected modules include them), etc. Here is a user guide for this new way to add starters to your project: https://github.com/spring-projects/sts4/wiki/Add-Spring-Boot-Starters-To...

Hello Martin,
Thank you for your answer.
Yes I know this procedure which you mentioned in the web link.
But I'm sorry, I prefer the old method with the 'Edit starters' option ...
When we choose 'Add starters', why in the graphical interface, you don't add an 'already selected' section in addition to the 'selected' section?
I think it's important to quickly have a graphic visual, rather than making a comparison with the xml file ...
The 2 ways can be complementary ...
Maybe it's hard to implement the code to be able to do this? ^^
Re: Re: Re: Hello,
Submitted by Martin Lippert on Thu, 2021-03-25 03:07
Hey Richard,
your feedback on this is much appreciated. The reason why we no longer do something like a "pre-selection" is starter modules that you already have on your project is based on the latest generations of the initializr project and the way that works. When you select starter modules in there, the resulting project might not exactly contain those modules exclusively. There is logic in initializr and some of the starter modules to do more sophisticated things, like automatically adding additional other starters for you. And there is no "inverted logic" in there, which infers which starters you would need to select in order to produce the set of starters that you have. Therefore we don't really have a way to implement this "inverted logic". (This gets even more complicated if users edited their pom.xml file (in case you use Maven) manually). Therefore we decided to not implement any logic to pre-select existing starters on your project. Sorry for not being able to bring this pre-selection back. Hope you find the new wizard useful nevertheless. If you have additional suggestions, please raise them as enhancement requests here: https://github.com/spring-projects/sts4/issues.

Actually, identifying dependencies of a project is not that complicated in an IDE, since the Maven integration for Eclipse in this case already does that work for you - and that is what the pom dependency analyzer tool would do as well in case I understood this. The difficult part is to calculate the pre-selection on start.spring.io that would lead to the pom that you analyze. It is not a 1-to-1 mapping (for a good reason actually, from the project-generation perspective).

Submitted by Martin Lippert on Tue, 2021-03-23 06:37
Hey! That sounds like an issue with the installation and the underlying bundles being maybe wired in a weird way. The best way forward would be a submit an issue at https://github.com/spring-projects/sts4/issues and tell us exactly which package of Eclipse 2021-03 you installed, which other third-party plugins you added, and how you installed the STS4 components then. I used the Eclipse JEE paclage of 2021-03 and installed STS4 from the Eclipse marketplace and that seemed to work, so we need to take a closer look at your exact setting in which you are trying to install the Spring Tools 4.
As a quick fix for you, feel free to download a ready-to-use distribution of the Spring Tools 4 for Eclipse from https://spring.io/tools. Version 4.10.0 of the Spring Tools 4 for Eclipse are a distribution built on Eclipse 2021-03, so you will get the latest in here as well.

If you want to install Spring Tools 4 into an existing Eclipse installation, you can choose the "Eclipse Marketplace..." menu entry, then search for Spring, pick the "Spring Tools 4" entry, and press the "Install" button.
The JAR file that you can download from the https://spring.io/tools page is a self-extracting full distribution of the Spring Tools 4 for Eclipse (including an Eclipse 2020-12 with pre-installed Spring Tools 4 extensions). You can download the JAR and double-click it. It will then self-extract the full distribution.

If you are not tied to Eclipse 2020-06, I could also recommend to download a ready-to-use distribution of the latest Eclipse release (2020-12) with all the Spring Tools 4 pre-installed from https://spring.io/tools.

Submitted by PEI YAO on Thu, 2020-06-18 10:04
Hey,
I just installed a fresh download of Eclipse version: 2020-06 (4.16.0) and then installed the Spring Tool Suite 4 for Eclipse (4.6.2 update e4.16) on my Windows 10.
It seems there is no Spring Boot Dashboard which was available in Eclipse 4.15.
How do I make the Spring Boot Dashboard available in Eclipse 4.16?
Any help is greatly appreciated!

That sounds indeed bad. Can you pleaee file a bug at https://github.com/spring-projects/sts4/issues/ for this and tell us how to reproduce this crash? Is it really the JVM that is crashing or is it a freeze at the UI, so that the process isn't responding anymore? Is there something in the Error Log View that relates to the problem? Or is the VM itsel crashing and in case that happens, is there a JVM crash log file tha you could attach? In case the process freezes, there is a setting in the "Preferences -> General -> UI Responsiveness Monitoring" that you could turn on to capture stack traces while the UI seems to be frozen. That would be great and help us a lot to find the underlying issues.

Error "Unrecognized VM option 'TieredStopAtLevel=1'" when run
Submitted by James Balaji on Sat, 2020-03-14 22:35
When use JRE1.7 to run my Springboot project, it fail to start with error "Unrecognized VM option 'TieredStopAtLevel=1'" shown in the eclipse console. But if I use JRE1.8, it's working well. Unfortunately, JRE1.7 is requested in my project.
I searched settings but can't find place to remove this VM option.
Could you tell me how to fix this issue?

This is part of some default options to speed up the exeution and launch of the Spring Boot app, but you can change that in the "Preferences -> Spring -> Boot", take a look at the "Fast Startup" section, where you can change those settings.

Thanks your answer, I found the place and remove the option. However, still not working with another error when I run the application.... seems it's stil a problem of JDK. I have synchronized all configuration place in eclipse with JDK1.7.0 (such as project compiler,classpath settings, eclipse preferences etc). Spring boot version I use is 1.5.9 Release.
The error is "Could not find the main class". then I copy the command and run in the dos window, it says that:"Exception in thread "main" java.lang.UnsupportedClassVersionError: cn/com/MainApplication : Unsupported major.minor version 51.0". I know the 51.0 means the version jdk1.7, but I am using JDK1.7.
Could you give some advice? Does STS4 support JDk1.7?
Re: Re: Re: Error "Unrecognized VM option 'TieredStopAtLevel=1'"
Submitted by Martin Lippert on Fri, 2020-03-20 05:10
STS4 in general supports implementing and running applications on top of a JDK7. You need to configure the JDK7 runtime environment in the preferences (as you probably did) and select it as the default for the JavaSE7 execution environment. Make sure it appears correctly as the entry in your project classpath containers in the packag explorer.
In addition to that you need to make sure to compile your project on a Java7 level by setting the compiler level in the Java compiler preferences for your project.
Then in the launch configuration, you should make sure that the JDK7 is used to launch the app. This "could not find main class" is usually related to some misconfigured JRE settings in the areas described above.
Hope this helps!

Can't create a project
Submitted by Pascal Houde on Thu, 2019-10-31 13:00
I have installed STS 4.4.1 from the Eclipse (4.13 64bit) marketplace and don't see the create new project option after restarting the IDE. There were no error during installation. I have tried with JDK 11 and 13 without success.
Re: Can't create a project

Sorry for the late answer, somehow missed the question here. You could analyze the underlying issue by opening up the console, opne an OSGi Host Console, and type in "ss" for "short status". If there is anything showing up as "INSTALLED", something went wrong with regards to the dependency resolution of bundles. This is hard to debug and to solve. In that case, I would recommend to download a ready-to-use distribution from https://spring.io/tools and go from there. If the list of bundles shows up fine (nothing in the "INSTALLED" state), then the wizard to create a new project using Initializr (e.g.) should show up ("Spring Starter Project") in a "Spring" category.

How to install the STS for the eclipse versions 4.6,4.7, and 4.8?
Re: Not compatible Error for Eclipse 4.8
Submitted by Martin Lippert on Thu, 2019-08-29 08:13
The latest version of the Spring Tools 4 for Eclipse require Eclipse 2019-03 as the base platform. If you want to instal the old Spring Tool Suite 3 package instead into an Eclipse 4.8 platform, you could use this update site using the "Install New Software" dialog: https://download.springsource.com/release/TOOLS/update/e4.8/ - it serves the STS 3.9.7 release, which is the last one compatible with Eclipse 4.8.
