sparse checkout gives me an error stderr: fatal: Not a valid object name HEAD

Question

When I try to do a GIT sparse checkout in Jenkins, I get the following error:

 > git rev-parse refs/remotes/origin/master^{commit} # timeout=10
 > git rev-parse refs/remotes/origin/origin/master^{commit} # timeout=10
Checking out Revision b1697de347cafa3afbd9efc364b2874994e88b0e (refs/remotes/origin/master)
 > git config core.sparsecheckout # timeout=10
 > git config core.sparsecheckout true # timeout=10
 > git read-tree -mu HEAD # timeout=10
Command "git read-tree -mu HEAD" returned status code 128:
stdout: 
stderr: fatal: Not a valid object name HEAD

I'm using the Multiple SCM plugin that Jenkins provides.

The files get copied to the directory, so I'm not sure why I'm getting the error.

The node is running on Centos 7

Answer 1

This (actually non-fatal) error went away for me when I updated the branch from master to */master.

Answer 2

Deleting jenkins job workspace fixed the issue for me
