Before upgrading to 4.0.0 I was using this plugin to get the code/apply a label to a branch based on the job parameter, so in my setup I have:

Server = http://myserver:8080/tfs/TFS2010
Project Path = $/${Branch}/DMSP/Request Administration

Where ${Branch} is the branch name, populated from a "Choice Parameter". After I installed the new version, I noticed that applying label is no longer working, my label name is:

"RequestAdministration-${AppVersion}"

But once the job runs its trying to apply the label to ${Branch} and not to the real branch name:

Creating label 'RequestAdministration-4.2.0.7' on '$/${Branch}/DMSP/Request Administration' as of the current version in workspace 'Hudson-RequestAdministration-MASTER'...
ERROR: Build step failed with exception
java.lang.RuntimeException: com.microsoft.tfs.core.exceptions.TECoreException: TF10122: The path '$/${Branch}/DMSP/Request Administration' contains a '$' at the beginning of a path component. Remove the '$' and try again.
at hudson.plugins.tfs.model.Server.execute(Server.java:110)

On the version 3.2 its works great:
[RequestAdministration] $ "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\tf.exe" label RequestAdministration-4.2.0.8 . -version:WHudson-RequestAdministration-MASTER -comment:Automatically_applied_by_Jenkins_TFS_plugin -noprompt -recursive -server:http://myserver:8080/tfs/TFS2010 ********

Thanks!
