NeoLoad plugin for Jenkins - some more problems

Hi all,

My initial problem with NeoLoad Jenkins plugin has been resolved with new plugin version (discussed here: http://answers.neotys.com/questions/1276130-neoload-plugin-jenkins-fails-start).

I'm now able to configure and run the NeoLoad job on Jenkins slave. However, I'm experiencing two more issues...

At first, once I run the job for the first time, it creates some subdirs in NeoLoad project ("libs" and "results"), and sets these dirs as "read-only". So the next time the job is started, TFS plugin (Jenkins itself) fails to delete the content of NeoLoad project dir with "Access Denied" error...

Deleted 1 workspace(s) named 'Jenkins-PLRM_NeoLoad-CPRAN04'.
java.nio.file.AccessDeniedException: c:\Jenkins\workspace\PLRM_NeoLoad\tfs\PLRM_NeoLoad\lib\extlib
at sun.nio.fs.WindowsException.translateToIOException(Unknown Source)
at sun.nio.fs.WindowsException.rethrowAsIOException(Unknown Source)
at sun.nio.fs.WindowsException.rethrowAsIOException(Unknown Source)
at sun.nio.fs.WindowsFileSystemProvider.implDelete(Unknown Source)
...

At second, "Test Result Name" fails to convert suggested build number variable. It only translates date variable. And if the build number variable is used together with date variable (as shown in plugin configuration help) the test fails to run.

This fails the job:
$Date{hh:mm - dd MMM yyyy} build ${BUILD_NUMBER}

This translates date:
$Date{hh:mm - dd MMM yyyy}

This shows exactly the same (untranslated) string in report name:
(build ${BUILD_NUMBER})
or
build ${BUILD_NUMBER}
or
${BUILD_NUMBER}

Thanks in advance.
