I want to use Jenkinsfile from local system, and thus I'm using hudson.NullSCM class of workflow-cps plugin. In earlier versions using this class didn't created any new directory. While in the latest version upgrade it is performing checkout and creating a new directory with random directory name, and searching the script in that location. 
I want a workaround or fix of this issue, as its a blocker in a Jenkins plugin that I'm working on.
