问题
I know that this question has been asked several times on StackOverflow (and others), but none of the solutions I've found works for me.
As you can see in the headline I am getting the following error message, when starting Android eclipse:
an error has occurred. see the log file
I have tried removing SNAP files and Vmargs directive from the eclipse.ini file. I've also tried to clean Eclipse with the command:
PATH/TO/ECLIPSE -clean
But with no result.
I am running the ADT Eclipse bundle on Windows 7.
And here is what my log file says (repeatedly) when I try to run it:
!ENTRY org.eclipse.core.resources 4 2 2014-05-26 13:45:14.494 !MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.core.resources". !STACK 0 java.lang.NullPointerException at org.eclipse.ui.activities.WorkbenchActivityHelper.isFiltering(WorkbenchActivityHelper.java:235) at org.eclipse.ui.internal.ide.IDEWorkbenchActivityHelper$3.resourceChanged(IDEWorkbenchActivityHelper.java:158) at org.eclipse.core.internal.events.NotificationManager$1.run(NotificationManager.java:291) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.events.NotificationManager.notify(NotificationManager.java:285) at org.eclipse.core.internal.events.NotificationManager.broadcastChanges(NotificationManager.java:149) at org.eclipse.core.internal.resources.Workspace.broadcastPostChange(Workspace.java:395) at org.eclipse.core.internal.resources.Workspace.endOperation(Workspace.java:1530) at org.eclipse.core.internal.events.AutoBuildJob.doBuild(AutoBuildJob.java:156) at org.eclipse.core.internal.events.AutoBuildJob.run(AutoBuildJob.java:241) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:53)
And this is what it wrote out as the last thing when/before I closed eclipse last time:
!ENTRY org.eclipse.ui.workbench 4 0 2014-05-25 21:37:47.323
!MESSAGE An unexpected exception was thrown.

I really hope some of you can help me fix this. The last time I closed Android eclipse, some problems occured because it was out of memory. I don't why this suddenly happened.
回答1:
Of course, just after posting the question, I've found the solution.
If others run into the same problem, try deleting the following folder from your workspace:
C:\.. \workspace\.metadata\.plugins\org.eclipse.e4.workbench
