I just installed a fresh download of Spring Tool Suite 4 for Eclipse from 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!

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 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?

mlippert's picture

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: - and add that as a local update site to your installation (just an additional option to try).

I am trying to install STS quick search on Eclipse Oxygen for MAC. I am getting the error 

No repository found at http:/

Is location of repository changed. How can I install?


mlippert's picture

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).

mlippert's picture

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 ("" and/or "") 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.

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 ( 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

When I select Gradle in new proyect, plugin show this error:

Can not import using Gradle (Buildship 1.x) because Buildship Gradle Tooling version 1.x is not installed.

mlippert's picture

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.

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!!!

jamaltheen20's picture

I tried the both steps but same error arised.

thank you for the quick reply.

mlippert's picture

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 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.

Thanks a lot. This helped me. I used e4.7 for Eclipse Oxygen and I could resolve the issue.

I've installed in an eclipse J2ee platform 4.6.3 (neon 3) the STS first downloading it from update site (...release/TOOLS/update/e4.6/) and then from the marketplace but Spring plugins aren't loaded properly .

I've looked for any of the custom spring elements inside eclipse environment, for instance spring perspective, or spring nature, spring preferences, but I found none of them.

Have I downgrade my eclipse j2ee installation to 4.6.2 or 4.6.1?
My previous spring installation is based on eclipse j2ee mars 2 and works fine even if it is a bit old.


mlippert's picture

Do you see any error? Maybe in the error log? I need a bit more details about the problem, since the general install should just work fine. An alternative approach would be to download the ready-to-use STS distribution from, which is a Neon.3 Eclipse with STS components pre-installed.

If you want to dive deeper into debugging what went wrong with the install, you could open a console view, switch to the OSGi Host Console, and type "ss" for "short status" to see which bundles are installed and what state they are in. If some of them are in the state "INSTALLED", something is wrong and we could dive deeper from there.

fcadili's picture

At least I installed STS on eclipse J2EE neon 3. The working sequence was:
1. install STS from market place on a clean up version of eclipse J2EE. (The installation form the updated site didn't work since I got a fatal exception at eclipse restart.)
2. Then install the other plugins.

Thank you. Francesco

mlippert's picture

Do you see any error message in the Error Log view that could be related? Or did the installation went smoothly and afterwards, you don't see anything in Eclipse? Isn't there a Spring perspective that you could select?

I am wondering which marketplace entry you chose. I tried to install STS 3.8.3 into Neon via the Marketplace a minute ago and it worked so far. Can you verify that you chose STS 3.8.3 from the Marketplace? I am also wondering why there is a bundle called "org.eclipse.net4j.jms.api" being installed. This is not used directly by the STS components, but maybe it is chosen by the underlying mechanism as a provider for jms packages? Maybe... Anyway, you could also try to install STS by using the update site directly in the "Install New Software" dialog (in case the marketplace entry continue to not work for you). Make sure you choose It would also be useful to check the configured update sites in the preferences (Install/Update -> Available Update Sites) and make sure that there is not another, maybe wrong update site configured (in addition to the correct one, mentioned above).

Can you try to remove the STS update site from the preferences (Available Update Sites), restart Eclipse, add it back, and try again? It looks like a temporary network issue, but that might have left stale cache data in the installation. The removal of the update site + restart should clean that up.

If that doesn't work, you can try to manually use the repo URL:

Hope that helps!!!

The problem was, that the following two .jar archives were corrupted:


The solution was:

1) Download the two artifacts manually for example from University of Kent UKMirror Service
2) Replace the two corrupted artifacts in C:\Users\smo.p2\pool\plugins\ with the manually downloaded ones
3) Reinstall the plugin over the Eclipse Marketplace

When I open Spring Dashboard, Eclipse shuts down.
There are some details from the log file:

Hard to tell what is going wrong here. You might want to switch to the old dashboard (via the preferences) if this crash happens again. Does this crash happen every time?

Use Luna Service Release 2 (4.4.2). After isntalling STS from eclipse marketplase i cannot find Spring Project Templates at menu (New->Other...) Can anyone tell me how can I fix it?

mlippert's picture

The wizard "Spring Project Templates" got replaced with "New Spring Legacy Project". You will find template projects there. But I would strongly recommend to create new Spring Boot projects instead, using the "New Spring Starter Project" and "Import Getting Started Content" wizards. They create up-to-date Spring projects. The templates are deprecated and no longer recommended. Therefore the wizard is already called "Legacy"... :-)

mlippert's picture

This looks like stale cache data from the p2 repositories. I would recommend to delete the STS repositories from the preferences (Update/Install -> Available Update Sites), restart STS, and add that update site again. That usually solves this issue.

After install newest STS, I can't create normal maven project anymore. It's not visible in new window. Does anyone know how to solve that problem?

hnguyen8g4's picture

I have the same problem after upgrading to the latest STS. The maven perspective/view is gone after upgrading to the new STS. Maven option is also removed from "Run As" and "Configure" menus.

mlippert's picture

I don't have an immediate fix for this problem at hand, but I would love to investigate this in more detail. Would you mind reporting an issue here: That would be great. We could continue the discussion from there. I think I will have to ask for further details (like the state of certain bundles, etc.), so the GitHub issue would make a lot of sense. Thanks!!!

mlippert's picture

I haven't seen this before and those issues are quite hard to debug/analyze. I guess this is caused by a compatibility issue on the OSGi level among the bundles. I think the best solution would be to start with a fresh STS distribution download.

ialami8n's picture

So far it was working properly. But today when I am going to reinstall it ( for some reason I need to uninstall it), it shows "The following solutions are not available: Spring Tool Suite (STS) for Eclipse 3.8.0.RELEASE".
Can anyone tell me how can I fix this issue?

I think if you deselect the entry 'com.vmware.vfabric.ide.eclipse.tcserver.insight' on the first dialog (called "Confirm Selected Features") then you won't get that popup. But if, on the 'not available' popup, you tell it to install anyway, it should succeed. We will look to fix for the forthcoming 3.8.1

Select this check box: "Contact all update sites during install to find required software"

so Eclipse will search all the bundles automatically which required by the software you are trying to install.

mlippert's picture

Looks like the installation procedure can't find the zest bundle, which is coming from the Eclipse Mars p2 update site (that one isn't included in the STS update site since I think it will be in every Eclipse Mars installation anyway). Can you check that and make sure that the main Eclipse Mars update site is in the preferences and activated? If so, the installation should work just fine (tried it again myself a moment ago). Hope this helps!!!
