The freestyle multi-branch project appears to have a serious issue. Or i am doing something wrong.
For each branch, when building, It adds a huge ID to the folder it builds to. Why?

E.g.:
NUnit_AM_Develop-E6QXPCKKZO7VWBORRTTWLSEHXX47QH6G5QVMNRI7IGDH4AB2CMZQ.

My branch name i AM_Develop and the config NUnit.

Hence the MS Build gives me a:
_The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters
_

If the project name is longer then "NUnit" i get the error just in the GIT pull.

How can i switch so the E6QXPCKKZO7VWBORRTTWLSEHXX47QH6G5QVMNRI7IGDH4AB2CMZQ is not present.
And is it even needed?
