Solution Description

Spring Tools 4

Spring Tools 4 is the next generation of Spring tooling for your favorite coding enrivonment. Largely rebuilt from scratch, it provides world-class support for developing Spring-Boot-based enterprise applications, whether you prefer Eclipse, Visual Studio Code, or Eclipse Theia.

Getting Started

Spring Tool Suite 4 makes it easy to get started. A direct and easy-to-use integration of the Spring Initializr and the famous Spring Guides allows you to go from nothing to a running Spring Boot app in seconds.

Navigate your Spring code at the speed of light

Understanding and quickly navigating source code is essential for coding. The new Spring Tools 4 understands your Spring-Boot-based source code and allows you to quickly get an overview and navigate to the important pieces of your Spring apps. Finding Spring elements and navigating to them has never been easier.

Smart Code Editing

Code completion is a critical part of working with source code. The all-new Spring Tools 4 provides smart code completions for the Spring elements in your app.

Runtime Information In Your Editor

Spring Tools 4 now bridges the gap between your source code and running Spring Boot applications. By taking advantage of the Spring Boot Actuators, we enriched the source code with detailed information from the running app (e.g., exact bean wiring information, conditional reports, configuration, details, and more).

Unable to read repository at download.springsource.com/release/TOOLS/sts4/update/e4.12/content.xml. sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

In reply to by László Bereczki

This is fixed and will be available as part of the next update release, coming out probably next week. If you want to try a nightly update site, you could install STS4 manually from https://dist.springsource.com/snapshot/TOOLS/sts4/nightly/e4.12 into your Eclipse 4.12 install. I haven't tried that yet, but maybe even updating your existing install with STS4 included (but broken) by adding this nightly CI p2 repo to your available update sites preferences might work - although I haven't tried this myself yet.

I had installed Spring Tools 4 in eclipse new version 2019-06, but it is not showing me Spring Starter Project. I had uninstalled and install it again still not working. Please provide a proper suggestion on it. I don't want to use "Spring Tools 4 for Eclipse" which is provided on "start.spring.io/" here. I want to use an independent eclipse.

I have same problem. After installed eclipse 2019-06 (withour any error). and installed Spring via eclipse market. But, I could not create a New Spring project. This problem should be solved as soons as possible.

Hello. I've installed this plugin on Eclipse 2019-06 and nothing changed in IDE at all. I didn't have any errors or anything. Just there isn't any Spring option in "New" menu.

In reply to by Georhii Prystupa

This might be related to an issue that I am investigating at the moment again. Are you running your Eclipse 2019-06 on JDK8? If so, could you try to run your Eclipse install with a JDK11 and a "-clean" option at least once to see if that changes anything? Another option to dianose the issue would be to open the "Console" view, switch to the "Host OSGi Console" and type "ss" for "short status". If there are certain STS bundles in the "INSTALLED" state, it might indeed be the issue that I am looking at right now and running with JDK11 should solve the issue. Another workaround would be to download a ready-to-use STS4 distribution from https://spring.io/tools, it works on JDK8 and JDK11 and comes on top of Eclipse 2019-06 with pre-installed STS4 components.

In reply to by rajnish singh

The URL that you mention (wih the "context.xml") doesn't exist indeed, but usually the update mechanism tries to access that and then tries the next variant, like the "compositeContent.xml" one. Maybe there is a proxy server in between that causes p2 not to recognize that this URL doesn't exist? What happens if you try "https://download.springsource.com/release/TOOLS/sts4/update/e4.11/" from the "Install New Software" dialog? Anything showing up?

In case the https protocol causes trouble (due to some network restrictions), you could also try the http variant (even though we don't recommend that), but maybe it helps in your situation at least.

When I try to install in version 2018-12 (4.10.0) I get the following error:

Unable to read repository at https download.springsource.com/release/TOOLS/sts4/update/e4.10/compositeContent.xml.
Certificate for <download.springsource.com> doesn't match any of the subject alternative names: [cloudfront.net, *.cloudfront.net]

What is wrong?



In reply to by James Kiryakoza

We tried to switch the repo URLs to https instead of http, but there seems to be some hurdles along they way. We are on it. For the meantime, I switched the marketplace entries back to use http. Caches might take a while to update to that, but after that, you should be able to install again. You can also download a ready-to-use distribution from https://spring.io/tools, which is Eclipse 2018-12 with Spring Tools 4 pre-installed.

In reply to by Karl Roth

Yes, our switch to https caused some hiccups, I am sorry for that. I updated the marketplace entries, they should use the http p2 repo URLs again for installs, but you might have to wait a bit before caches are being updated. Another option would be to install the ready-to-use distribution from https://spring.io/tools.

Version: 2018-12 (4.10.0)
Build id: 20181214-0600

This version of Eclipse prompts the user to choose one of the bouncy castle distribution (Sun or Oracle), during STS Installations. Earlier versions used work if we choose Sun for example. Latest version unless we choose both does nothing. Throws no error at all, but quietly does nothing. After restarting eclipse we will find STS is not installed. It completes the installation only if we choose both.

Earlier versions of Eclipse with STS4 nicely used to have "Srping Config Editor" to open spring integration xmls, so that we could have the graphical view of Integration Graph and more. No longer that's the case with latest Eclipse version. Details as follows.

Unable to install from market place. Getting message "No repository found at .../download.springsource.com/release/TOOLS/sts4/update/e4.9/."

The problem is that ulr leads me to cloudflare and asks to enter CAPTURE.

In reply to by Ilarion Ishkulov

Yeah, Cloudflare caches the content for us, so that is fine, but the capture is strange and should not happen. But the URL is not meant to be used in a browser, so not sure where the capture appears...?!?

I would recommend to remove the update site URL from the preferences, restart STS, and try again. If that doesn't help, you could also try to go to "Install New Software" yourself (in your Eclipse installation) and select the update site there to see if that works. You could also try to use a slightly different one (http://download.springsource.com/release/TOOLS/sts4/update/latest/ or http://dist.springsource.com/release/TOOLS/sts4/update/e4.9/) - as a third option to try.

I just get the message "No repository found at .../download.springsource.com/release/TOOLS/sts4/update/e4.9/." when I try to install with Eclipse Marketplace.

In reply to by Steven Edmunds

This is usually caused by a network glitch and stale cached data afterwards. Please go to the "Preferences -> Install/Update -> Available Update Sites" and remove to corresponding update site from that list (not disable it but remove it completely). Then restart and retry. That should solve the issue.

Another option would be to go to https://spring.io/tools and download a ready-to-use distribution of Spring Tools 4 for Eclipse, it is based on the latest Eclipse 2018-09 release and comes with the Spring Tools 4 pre-installed.

I just installed a fresh download of Spring Tool Suite 4 for Eclipse from spring.io on my mac (highSierra) but cannot open the Spring perspective (a small red square appears in front of Spring selection element).

No change after manually deinstalling/installing Spring Tools 4 (aka Spring Tool Suite 4) and running -clean.

Any help is greatly appreciated!


In reply to by Martin Schoepf

Spring Tools 4 don't contain any Spring perspective anymore, the major elements got added to the regular Java perspective, since that is what most people use for daily Spring Boot app development. So if you open an existing workspace that had the Spring perspective open from STS3 with STS4, you should close that perspective and continue with the Java one instead.

Using Photon on Windows 10, downloading org.springframework.tooling.cloudfoundry.manifest.ls is failing because it is not available via HTTP and only HTTPS. I have changed the location in Prefences > Install/Update > Available Software Sites to use HTTPS, but it gets switched back to HTTP and duplicates the listing. I have tried reloading and it does not work either. Any ideas? Can I manually download the manifest and put it someplace?

In reply to by Phil Cogbill

Downloading an individual bundle is possible, but it doesn't really help much, since you can't easily install that into your Eclipse. What happens if you go to "Install New Software" and put the HTTPS version of the URL in there? Does that work?

I am not aware of any mechanism that replaces the HTTPS automatically with the HTTP one and I am sure that the P2 repository that contains this bundle is available via the HTTP as well as tne HTTPS version of the URL. So maybe some network specific settings/proxies in your environment?

You could also try and download the whole STS 3.9.5 update site for Eclipse 4.8 from here: https://spring.io/tools/sts/all - and add that as a local update site to your installation (just an additional option to try).

In reply to by sameer saurav

The repository location hasn't changed, I guess there is an issue with stale data in the cache somewhere. You can go to the preferences, select the update location, and press "Reload", that usually helps. If not, remove the update site from the preferences, restart Eclipse, and add it back again (Preferences -> Install/Update -> Available Update Sites).

In reply to by manish raj

This looks like a typical network or repository caching issue. I would recommend to go to the Preferences -> Install/Update -> Available Updtae Sites, select the one that is used ("dist.springsource.com/release/TOOLS/update/e4.6" and/or "dist.springsource.com/release/TOOLS/update/3.9.2.RELEASE/e4.6/") and press "reload". That refreshes the internal repository caches. Then try again the install. You could also delete all those STS-related update sites from that preference and try again the marketplace entry. That should solve the issue.

I'm an admitted n00b; error is below. If there is a better place to be posting/seeking help with this please advise!

In reply to by Paul D

Not sure how exactly you are trying to install the Spring Roo support (and why) and from which update site, but using the STS product update site from here (http://dist.springsource.com/release/TOOLS/update/e4.7/) should work. Otherwise I would recommend to download a ready-to-use STS distribution from that site and use the Dashboard to install the Spring IDE Roo extension from there.

MIght be a corrupted download or stale cache data in the p2 pool. I would suggest to delete the file, open Eclipse again, check the preferences if the STS update site already landed there and if so, select it and press "reload", just to make sure caches are invalidated. Then try again. Another option would be to use the update site directly or download a ready-to-use Eclipse distribution with the STS tools pre-installed via https://spring.io/tools.

In reply to by Adrian Degenhardt

In case you select Gradle as the build environment when importing or creating new Spring projects, you need to have some kind of Gradle support installed in your Eclipse environment. We strongly recommend to use Buildship 2 for this. The error message indicates that you probably don't have that support installed.

You can get Buildship from the Eclipse Marketplace (right from within Eclipse using the Help menu). Once you have that installed and select Gradle in the import wizard, the error should not appear anymore.

In reply to by jamaltheen S

The mentioned artifacts are available, so it looks like there is some stale cache data somewhere. I would recommend to go to the Preferences -> install/Update -> Available Update Sites, select the one for STS (or multiple ones if you have more than one), and press "Reload". That should cause the cached data to be refreshed.

If this doesn't help, you could try to remove the update site from that list (in the preferences), restart Eclipse, and add it back to that list.

Hope this helps!!!

In reply to by jamaltheen S

In that case I would remove all STS-related update sites from the preferences and restart STS. Then go to the "Install New Software" dialog and put http://download.springsource.com/release/TOOLS/update/e4.5 into the update site URL field (if you are running Eclipse 4.5). Then select the components you want to install and continue. Make sure you have the main Eclipse Neon update in your preferences and active, so that missing components will be fetched from threre.
