If the name of multibranch job is more then 15 characters, it will be truncated when the name of the workspace directory is created.  This is because there is a large generated string which is prepended to the directory name.  

The request is to reduce the size of the generated string, so that the name of the job can be longer then 15 characters.

In the attached screen shot the job name is "Build_System_Documentation_multibranch_01".   The directory name shows that the first 15 characters of that have been dropped.

Just noticed, the name of the branch is in there also.  So most likely it is another 12 characters  for that.  So something like a current total of (15 + 12 =) 27 for job name + branch name, before things start to get truncated.

Thanks.
