      When the Mercurial branches of a Multibranch Pipeline are scanned, the process fails as soon as it encounters a branch without Jenkinsfile.

      It fails on:

      ERROR: Failed to run /usr/local/bin/hg locate -r afd44e0ab2ea0a567d0262f564bf539115382e3c -I path:Jenkinsfile

      Presumably this happens because hg locate returns an error code, and the code does not expect this. This could be because a similar command for Git does not return an error code.
