Hello
within a continous integration plugin for the automated build of CDT
projects I perform SVN checkout via subversive-api.
I use the org.eclipse.team.svn.core.operation.remote.CheckoutOperation
executed within a org.eclipse.core.resources.WorkspaceJob like:
public class SvnCheckoutJob extends WorkspaceJob {
public IStatus runInWorkspace(IProgressMonitor monitor) throws
CoreException {
...
CheckoutOperation op = new CheckoutOperation(resourceMapping, false,
null, Depth.INFINITY, true);
op.run(new SubProgressMonitor(monitor, 1));
}
}
In the subsequent build of the projects I get sometimes errors of the types
ResourceException thrown by
org.eclipse.core.internal.resources.Project::internalBuild (522) or
NullPointerException thrown by
org.eclipse.cdt.managedbuilder.internal.core.ManagedBuildInf o::getConfigurationNames
(226)
The errors occure very sporatic, but only after checkout, never if just
update on existing projects of a workspace was performed.
Do I miss some refresh-operation as follow-up, or do I have to switch to
another thread-context here??
Any help would be great, as I'm already struggling for weeks with that
problem.
Thanks in advance,
Kevin Russ

Hello Kevin,
It's hard to say what the problem could be.
You said that you have two kinds of errors
(org.eclipse.core.internal.resources.Project::internalBuild and
NullPointerException), could you write what the problem they are talking
about(or what is reason of NPE) and so we'll be able to understand where the
problem is.
Probably, you have problems during check out, do you have any related
messages in Error Log view? Is the project checked out correctly?
Maybe it's not important but you wrote that you used WorkspaceJob ("A
WorkspaceJob is the asynchronous equivalent of IWorkspaceRunnable"), so try
to run check out operation synchronously.

Hi,
thanks for your answer!
The checkout seems to be successfully,- I get no messages in the error-log.
I remeber that I've once traced an NPE down till ManagedProject from
org.eclipse.cdt.managedbuilder.internal.core, were the configMap contained
a null element. But had no idea what the cause could be.
Strange to me is the following: If any of the errors after automted
checkout and build occure,- they woun't disapear for the specific project
even on manual refresh and build, until I restart the workbench... then
everything is ok again. This implies that the project was physically
checked out correct, right ?
My plugin does in short terms the following:
Within a scheduled job serveral operations are performed subsequently.
If anything critical to workspace is done (SVN Checkout, Setting
Configurations, Build a Project, etc.) I always start a WorkspaceJob with
a specific job-rule (project or workspace) and wait for termination via
join().
The error ocurence sound to me a bit like a race-condition. We have over
one hundered projects to build per run and maybe every 2. or 3. run will
fail by such an exception.
So I'll try your tip with the IWorkspaceRunnable as next...
Kevin.
