Since updating from 2.0.1 to 2.0.3, a job which uses tags containing a slash as "branch" does not work anymore (rel/x.y.z-... in my case)
I my case, a sepate job creates a release tag (refs/tags/rel/my-tag).
The job that stopped to work tries to check out this given tag (using a parameter: so the branch field contains the value: rel/$version)
Using git plugin 2.0.1, this works. Using git plugin 2.0.3 the checkout attempt results in "Couldn't find any revision to build. Verify the repository and branch configuration for this job."
Downgrading to 2.0.1 solves the problem.
The problem has already been discussed in
JENKINS-14026, but the applied fix only works for slash-less tags
