Description kurt

2015-12-09 05:51:20 EST

Doing a TeamProjectSet-Import (CVS) causes error 'Preference node "org.eclipse.jdt.core" has been removed.'.

After that, the project(s) are in an unusable state.
Most it helps to close, open and then clean the project(s).

As this error does not always show up, I think it is kind of a timing-problem while updating the project(s) and notification-events (their listeneres) in the workspace.

If I am right, maybe following could be a solution:
  in org.eclipse.team.internal.ccvs.core.CVSProjectSetCapability.checkout(...)
  setting the flag AVOID_UPDATE for ResourcesPlugin.getWorkspace().run()
  instead of 0 (IResource.NONE).

Eclipse CVS Client:
  Version: 1.4.200.v20150603-2000
  Build id: I20150603-2000

Most of the time the error occurs, also a dialog 'Problem Occurred' shows up.
Details:
  Errors occurred during the build.
  Errors running builder 'Java Builder' on project 'BS_REGISTR'.
  Preference node "org.eclipse.jdt.core" has been removed.


And following errors are logged (once per project):

update:
  the same is valid for the public static void checkout() - method in CVSProjectSetCapability

Comment 2 Jay Arthanareeswaran

2015-12-14 00:22:19 EST

Moving to CVS

Comment 3 Szymon Ptaszkiewicz

(In reply to Jay Arthanareeswaran from comment #2)
> Moving to CVS

CVS plugins do not appear anywhere in the stack traces so I'm not sure what we can do on the CVS level. Jay, can you please clarify?

Comment 4 kurt

2015-12-14 06:22:33 EST

Clarification:

You won't see 'CVS' on the stacktrace, because the error is triggered by a delta-listener (running in parallel) while checking out.

Both methods (private checkout and public static checkout) of CVSProjectSetCapability use ResourcesPlugin.getWorkspace().run() with flags-argument set to 0 or IResource.NONE.

This probably causes notification-events sent while cvs-oparations are still in progress (see 'boolean avoidNotification = ...' in Workspace.run()-method for that).

As I mentioned before - it's a timing problem also, so it is not easy to reproduce for every test.

Comment 5 kurt

2015-12-14 06:51:40 EST

Just could reproduce the problem - with 'CVS on the stacktrace':

I cleared the log before - so all these error occur on importing one single project.

In the second entry you find CVS on the stacktrace.
And following the stack, you'll find more ResourcesPlugin.getWorkspace().run() with flags set to 0 (for example: EclipseResource.run()).

Hope that helps.

For my tests I used 'Replace with ...' from the context menu of the project before doing the TeamProjectSet-Import.
The problem never occured within 'Replace with ...'.
Looking at ReplaceOperation.executeCommand() you can see that it calls ResourcesPlugin.getWorkspace().run() with flags set to IWorkspace.AVOID_UPDATE.
I think, thats a 'strong argument' for my opinion.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug.

If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
