In my global configuration, I define a variable as follows:

BUILD_NAME = ${JOB_NAME}r${SVN_REVISION}_b${BUILD_NUMBER}${BUILD_ID}

I then use this build name for the naming of folders and artifacts. This seems to work correctly, but about 80% of the time the SVN_REVISION is empty leaving my BUILD_NAME to contain "r" instead of "r####" as expected.

I have tried using SVN_REVISION_1 as well.

When I view the environment variables after the build is finished, it shows that both SVN_REVISION and SVN_REVISION_1 are set.

If this did not work at all I would not have a problem, but the fact that it is seemingly random shows me that it can work but there are some issue that can hopefully be fixed.
