Howto get local Jenkins with branch in local mercurial repository to work?

Question

I have set up a local jenkins with mercurial plug in that should clone a local repository, i.e. Repository URL = C:\repo is a local path. I work on a branch, that's why I also added branch = myBranchName, but I don't believe this causes my problems.

If I start the job an error occurs and in the console I find (translated by me)

started by user anonymous
Building in workspace C:\jenkins\jobs\LocalRepo\workspace
$ hg clone --rev myBranchName --noupdate C:\repo C:\jenkins\jobs\LocalRepo\workspace
adding changesets
adding manifests
adding file changes
added 7905 changesets with 42182 changes to 10043 files
[workspace] $ hg update --rev myBranchName
abort: C:\jenkins\jobs\LocalRepo\workspace\Server/src/main/resources/com/application/resources/FileWithReallyReallyReallyReallyLongFileName.properties: The system cannot find the given path
ERROR: Failed to update C:\repo to rev myBranchName
Finished: FAILURE

I can reproduce the error in the command console with mercurial (translated again):

/cygdrive/c/jenkins/jobs/LocalRepo/workspace $ hg branch
default
/cygdrive/c/jenkins/jobs/LocalRepo/workspace $ hg hg update -C
Cancel: C:\jenkins\jobs\LocalRepo\workspace\Server/src/main/resources/com/application/resources/FileWithReallyReallyReallyReallyLongFileName.properties: The system cannot find the given path

The file really exists under C:\repo but not under the cloned directory C:\jenkins\jobs\LocalRepo\workspace.

What am I doing wrong? The absolute path is in my real application 269 chars long. Is that really the problem? Is that no problem for mercurial in the real repository C:\repo because jenkins writes the file in the deeper and longer path C:\jenkins\jobs\LocalRepo\workspace\? If that really is the problem how could I solve it best?

Yes. The maximum path length in Windows is 260 characters.
