Hi,
I developed a plugin for Eclipse successfully. The development went just
fine for several months, without any problems.
But some days ago a problem started to occur:
when I start an eclipse instance to test the plugin (using the default Run
command from the PDE), an instance starts, but after some seconds the
class files of my plugin are removed!
So then I can't execute my plugin of course.
I also did a Clean of the project and run the eclipse instance again, but
the same problem.
When I export the plugin, install it on a separate Eclipse instance and
launch it, there is no problem, but I can't develop anymore with this
problem.
What makes the problem even worse, is that the class files are not removed
simply every time, but most of the times. So sometimes an Eclipse instance
is started and the class files are left untouched.
Any idea what causes this problem, or where I can find clues?

That's very puzzling indeed.
For debugging, you might try making all of the .class files read-only in
your filesystem just before launching. That way, when whatever is
deleting them tries, it will fail and you might get some messages in the
error log about the failure. Such errors could point you to what is
doing the deleting. Make sure to check the error log of the launched
Eclipse, not the one you're developing in.
Hope this helps,
Eric

Thanks Eric, that helped!
The problem was that the launched Eclipse application accidentally
contained the plugin project in its workspace. And after Eclipse was
launched, the Java builder got into action for that project, and deleted
the resources.
