So I was working on eclipse when I received this issue
The 'API Tools Javadoc Proposals' proposal computer from the
'org.eclipse.pde.api.tools.ui' plug-in did not complete normally.
The extension has thrown a runtime exception.
This happened directly after I installed Java-8 into eclipse.
Now my understanding that this is a comparability issue so I tried multiple things as shown below, however I still face the same issue
1- I have tried help->Check for Updates
So it performed some updates normally but the same issue remained as it is
2- I have tried help->Install new Software to install JAutodoc
So I got the link for their website and installed the latest update I believe, however the same issue remained.
Website: http://jautodoc.sourceforge.net/
Update link: http://jautodoc.sourceforge.net/update/
As for someone not familiar with this tool, I believe that I might have forgot something. However searching through the internet did not help me.
Any suggestions ?
See this bug report: https://bugs.eclipse.org/bugs/show_bug.cgi?id=433918
Like the poster in the bug report, I was able to fix this (in Kepler) by uninstalling everything to do with the Groovy plugin. After uninstalling the groovy pieces I had to reinstall java 8 support from this Kepler-specific link, and then I was able to reinstall the Groovy plugin using the J8-specific groovy eclipse link in the bug report: http://dist.springsource.org/snapshot/GRECLIPSE/e4.3-j8
Then once I fixed the compiler compliance level in my project to 1.8, things were working again.
(Took me a while to find how to uninstall things: Help -> Install new software, and then click the little "already installed" link at the bottom.)
From the bug report, it sounds like this bug wouldn't happen in a newer Eclipse (Luna or Mars.)
I just ran into the same problem today.
I solved it as follow (I have a mac, instructions for other operating systems might differ)
Open Eclipse
About Eclipse
Installation Details
*Find org.eclipse.pde.api.tool.ui
*click update.
Updating the plugin solved my issues. I am not sure if this solution works for everyone but it works for me.

I am having no success at installing UML Designer in Eclipse for Java Developers.
I have tried 6 different versions of the Eclipse IDE, going back as far as 2020-09. I have also tried installing Sirius first, but that also resulted in errors during installation. Finally, I have tried both the Eclipse Marketplace route and the "Install new software" route using the software repository URLs. Lastly, I have combed the internet looking for a "how-to", or similar, without any luck.
I assume, given that this discussion category is ongoing, that it is possible to install UML Designer in some version of Eclipse. :-) Can somebody please walk me through the exact steps that were followed to achieve a successful install?
Thanks for any help!
I just downloaded the latest Spring Tools 4 package, 4.3.2 RELEASE. My code base makes widespread use of AspectJ, and every time I try to import a project, I get a "Marketplace solutions available" dialog saying my IDE is missing natures to properly support my projects. It offers org.eclipse.ajdt.ui.ajnature as a solution, but the marketplace won't install it. When I try to access it directly through the Eclipse marketplace in my browser, I get an error dialog saying it's not compatible with this version of Eclipse. I'm using Java 11 on Linux. It's a little hard to figure out which version of Eclipse is embedded in this tool, but it appears to be Eclipse Equinox. Thanks for any help or suggestions.
The link provided by howlger http://download.eclipse.org/tools/ajdt/48/dev/update was the missing piece of information. That solves the problem, everything builds.
I was using eclipse IDE for java Developers, then a notification for update comes through, I've accepted it, everything is ok, restart needed, ok.
after opening, I've shocked that it became IDE for Web Developers, and all my projects became full of errors, and can't make a new java project.
I can't just download another version of eclipse for java ee, because I have a lot of plugins installed, and many configurations made.
How I can return back to the previous version?
Any suggestions please
You should be able to download and install the older version of Eclipse again:
Don't try to reinstall on top of your existing installation. Move or copy the existing Eclipse installation directory somewhere else before you start.
I would also advise making a backup of your workspaces before you do anything else. It is unlikely that the upgrade / downgrade will do any damage, but you can't be too cautious.
The errors that you are seeing are likely to be due to a simple Eclipse configuration problem, or maybe a problem with versions of third-party plugins. If you told us what the errors were, someone would be able to tell you how to fix them. Then you can use the newer version of Eclipse.

Actually, neither of those things prevent you from doing that. Downloading and reinstalling will be inconvenient ... but it is probably your best option.
Note that you could either download and install the new version of Eclipse, or you could download and install the version you were using previously.
I think it's no matter. I suggest to you use Spring Tool Suite based on Eclipse 3.**; You don't have to deal.
Today I turn on my laptop and STS shows me this error, and I dont have any idea, Why STS is raising this.
My java home is :
and my gradle project is using java 1.7.
Maybe you can help me to solve this problem.
Thank you.
This can be related to having multiple jdk installs and can be fixed by renaming the other jdk folders, however the true problem here may be caused by a symlink in /jdk1.8.0_71/jre/lib/tools.jar pointing to jdk/1.8.0_71/lib/tools.jar. Remove the symlink and see if Gradle works.
I am using Eclipse to program in Java. I tried installing from this site though Eclipse's Updater but although it didn't fire any error, I don't see the menus they say I should.
Maybe I have to install something first? Maybe there other simpler JML options? What you guys use?
The problem was that I didn't have JDK installed (just Eclipse's stand-alone package). Installing the JDK and reinstalling JML in Eclipse did the trick.
You should open the Error Log view and see if it contains any relevant errors.
