Eclipse sometimes behaves in weird manner. All all your source code folders ok? Please check all folder first. If they are ok then there must be something with the core plugins OR the workspace in which you have all your projects.
First copy your workspace, then install another instance of eclipse. Try to open the workspace in that eclipse.
If that doesn't work, it seems a big problem. May be you need to import all projects again in new workspace.
For better performance, you should keep number of projects in workspace somewhat limited. It seems you have many projects inside one workspace which might cause memory problems and slower your eclipse.
I hope, this works for you.
---EDIT on 21st May,2010---
After searching it ,it seems a bug in eclipse 3.4. Thought it shows a bug of WinXP, may be it affects MAC also.
Please check the link below. They have specified version 3.4 M6.
So if you are using older version of eclipse then please get newer from this link.
Also please check to have JDK 1.6 (Stable version) installed on your mac.
Eclipse download: http://www.eclipse.org/downloads/
Bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=217707
Hope this helps.
thanks.

Can you check the Console (Applications -> Utilities -> Console.app) and see whether there are any specific messages from eclipse (and post them here if possible)?
A exception stack trace or something?
Maybe it might throw some light on whats going wrong.

Eclipse Refactoring (Renaming) throws ExecutionException caused by NullpoinerException

While coding yesterday I stumbled over a sudden error occuring in my Eclipse IDE. I wanted to rename a variable and pressed (as I should and I am used to) ALT + SHIFT + R. This however opened Run in the toolbar. I thought ok maybe I pressed wrong keys but this error kept happening.
I then tried to restart Eclipse, reload the project (deleted it but not the content on the disk and loaded it again by importing) and also deleted the workspace but the error still occured.
Then I thought maybe the installation is somehow broken so I reinstalled Eclipse (btw. I am using the latest 06-2020 Version). This did not help either though...
After a lot of using Google I also found the following articles this question might seem to be similar to
Can't refactor rename in Eclipse
Eclipse refactoring fails -> Keeps throwing exceptions!
https://www.eclipse.org/forums/index.php/t/375178/
but the suggestions in these did not work for me.
What I saw while browsing the Error-log was that a lot of errors occured while using the rename function. I hope someone has a suggestion how to fix this because also renaming with mouse doesn't work any more.
Some more details:
Error suddenly occured > It worked all the time and suddenly stopped working without (at least me) knowing about any changes
I am using Windows 10 with OpenJ9 JDK14 as the default JDK an JRE so eclipse also uses this JRE

This looks like Eclipse bug 564329 which is marked as fixed in Eclipse core 4.17 M1 (Milestone 1). So this fix will be in the 2020-09 release scheduled for September 2020.
Temporary fix: Window > Preferences > Java Compiler > turn off "Enable preview features for Java 14". Enable the "Use default compliance settings".
Enable preview features setting

Subclipse: Error with SVN after an update (Unable to create SVN preference page)

Good afternoon,
I have been using Eclipse and Subclipse (with JavaHL) for a few months without any problem so far. After an update of some plugins (including Subclipse) yesterday (i.e. on 13/03/19), subclipse is no longer working.
For example, I am no longer able to commit or pull any file and when I get a look at window > preference > Team > SVN, eclipse displayed the following message:
Unable to create the selected preference page.

I am working on Ubuntu 16.04. I've already tried, without any success to:
Uninstall and reinstall subclipse via the Marketplace
Uninstall and reinstall subclipse via Help > Install New Software... providing the link to Subclipse binaries (https://dl.bintray.com/subclipse/releases/subclipse/4.3.x/ or https://dl.bintray.com/subclipse/releases/subclipse/latest/)
Use a new empty workspace
Perform a clean install of eclipse and subclipse with a new empty workspace on the same computer
I also tried to install subclipse on an other computer (where eclipse was installed but on which subclipse has never been installed), and it seems that I met the same problem...
I would be really grateful if anyone could give me some insight about what's going wrong here or how to solve this problem,
Thanks by advance!
Sébastien
It is not a problem per-se and is more or less explained in the docs:
https://github.com/subclipse/subclipse/wiki
The current version of Subclipse supports SVN 1.11 or 1.10. On every OS except Windows you are responsible for providing the native libraries (see the JavaHL links on above page). Your error is that you installed the 1.11 support but you have the SVN 1.9.x native libraries installed. You do not mention your OS, but one solution would have been to update the installed SVN client to 1.11.
As noted further down on the page, if you are stuck on SVN 1.9.x client then you have to install the older Subclipse 4.2.x version which supports 1.9.
If you can get 1.10, but not 1.11 then you just have to uninstall the 1.11 JavaHL plugin and install the 1.10 plugin. Both are on the Subclipse update site.
I finally found a way to fix this problem.
I performed a clean install (after having deleted all files related to eclipse - which includes obviously the folder where eclipse was installed but also the .p2 and .subversion folders in the home directory, excluding the workspace where I did not remove any file) and installed subclipse via the Help > Install New Software..., providing the link to the previous version of Subclipse, i.e. Subclipse 4.2 (https://dl.bintray.com/subclipse/releases/subclipse/4.2.x/). And all is working well again so far.
I think that people who meet the same problems as mine could also fix this by a simplier way by reverting the install prior to the last update (avoiding then to perform a completely new install...) going throught Help > About Eclipse IDE > Installation Details >Installation History and then selecting the last installation and clicking to revert. Nevertheless, I was not able to do this as I modified some files which seem to be necessary for Eclipse to do this. So I do not know for sure if this second method is working...
Even if this is a way to fix that matter, I do not understand what is going wrong on the current Subclipse version (4.3). In particular is this a problem which is known and reported for the current version (but in such case I did not find any documentation or question raised about it...) or something related to the configuration I use or something I did?! If anybody have some idea about this, I would be happy to understand :)
An alternative workaround is to not install the JavaHL part of the plugin. Then it uses SVNKit instead, and the preference page works again.
I met this error, because the version of libsvn-java installed on Debian Buster (1.10.4-1+deb10u1) does not meet the requirement of Eclipse 2020-03: at least 1.12.0.
Simply running
sudo apt-get purge libsvn-java solved the problem, because Eclipse then fell back to SVN Kit. The moral being: having no JavaHL installed is better than having too old a version.

Why is eclipse giving me this error?

Ok, so I installed this plugin for eclipse. I dragged all the stuff in it's features folder into eclipses, and all the stuff from it's plugin folder to eclipse's plugin folder. I also copied the site.xml into eclipse's main folder. But when I started eclipse and tried to view class files, they gave me a eclipse error. I tried uninstalling it, but it didn't show it was installed. I also tried removing the base files I copied, but it still gave me the same error.
The error, up close, is this:
org.eclipse.core.runtime.CoreException: The Class File Viewer cannot handle the given input ('org.eclipse.ui.ide.FileStoreEditorInput').

And a screenshot of the screen is this:
You have not installed the plugin the proper way, it most likely will not work. JD-Eclipse page tells you how to install it correctly. Even if you download archived Update Site, you must use the Install New Software... dialog. The only thing you should do differently in given instructions is in New Repository dialog instead of pasting the Update Site URL into an input - click Archive... button and select zip file you downloaded.
You should not have broken the whole installation by simply copying the jar files into respective folders, but apparently somehow it was corrupted or some bug exposed which threw the given Exception. Exception, actually, looks like it is the Standart JDT Class Editor which failed not the JD-Eclipse.
I suggest you shutdown Eclipse, delete all the files you copy pasted manually, launch it again and try to open some class file in the Workspace. If it works, try to install JD-Eclipse properly (including Microsoft Visual C++ 2008 Express Edition if you are on Windows). If it does not work, try re-installing Eclipse.
What and where you put class files that you want to view ? Are that class file exists in your workspace? If not, try to put your class file in your workspace
For quick and dirty checks, I've found a better option: go to http://jd.benow.ca/ and drag and drop your class file onto the "Live Demo"->"Input Files" section at the bottom. Worked like a charm!

Unhandled event loop exception when I open a JSP file in eclipse helios

I want to generate Crystal Reports in Eclipse for which I have recently downloaded crystal reports 2.0 for eclipse. I am using eclipse-jee-helios-SR2-win32 (3.6) version and Tomcat v5.5 server version.
I can generate the JSP file from the Crystal Report file(.rpt) as shown in this PDF. But the problem is when I open it. It cannot be opened by any editor except Text Editor.
On opening with other editors gives me following Error:

I think I am forgetting something in installation process. Can anyone help here please Thanks in Advance !!
EDIT: Solved this error when I deleted files:
org.eclipse.jst.jsp.ui.source_1.1.601.v201108151912.jar
org.eclipse.jst.jsp.ui_1.1.601.v201108151912.jar
and downloaded:
org.eclipse.jst.jsp.ui.source_1.1.401.v200908111935.jar
org.eclipse.jst.jsp.ui_1.1.401.v200908111935.jar
But now I lost complete support of JSP from Eclipse.
Refer this for more information.
Solved this error when I uninstalled following plug-ins from Help->About Eclipse SDK->Installation Details:
Android DDMS, Android Development Tools, Android Hierarchy Viewer,
Android Traceview.
Eclipse Java EE Developer Tools
JST Web UI,etc...
And then again Re-installed them.
Finally I got JSP support on Crystal Reports(.rpt) files as well as complete Android support on Eclipse.

GWT Designer m_selectedModuleFile error

This is my first time working with GWT. I am following the tutorial at: http://code.google.com/webtoolkit/tools/gwtdesigner/tutorials/stockwatcher.html
I can't get beyond the creation of the GWT Java Project. When I click Finish I get: An error has occurred. See error log for more details.
m_selectedModuleFile

Also, when do you use WinBuilder, and when should you use GWT Designer or the Web Application Project? I am unsure of the differences between them all. I'm looking for something to not an eye-sore that can be used with App Engine with some form entries.
It turns out I had an old version of WindowBuilder, and that was contributing to the problem. Not sure if that was the entire problem, though. It's worked so far.
This seems like something might be off in the install. I usually install Eclipse Java EE edition (not same as Java), then the GPE minus the Android parts (unless I need to set up for that too, then install the Android SDK before the GPE), then WindowsBuilder - for the extra wizards. After that everything just works. I create a new GWT project (using sample code - much easier that way to get started), then can use any of the wizards.
