Description
Not sure if this affects production systems, or indeed why it is not reported by everyone, but anyway I was unable to make AbstractGitSCMSource.retrieve(SCMHeadObserver, TaskListener) work in a test without this fix. (And there was no test for it.) Doing so failed with:

Perhaps some, but not all, versions of git-client barf if you try to run git init in a nonexistent directory?

Merge pull request #432 from jglick/mkdirs-JENKINS-37482
JENKINS-37482 Make the cache directory, not just its parent
Included in git plugin 2.6.0, released 2 Sep 2016.
Thanks for the pull request to resolve this.
The JGit implementation in git-client will create the directory if it does not already exist. That's why this condition was not detected previously by those using the multi-branch pipeline plugins. They previously only used the JGit implementation. The command line implementation in git client does not create the directory if it does not already exist.
PR424 detected that same condition and has a change in the git client command line implementation to create the directory if it does not already exist.
