When svn location path contains variable, then jenkins checkout the code from trunk.

This is the ulr configured in Jenkins for SVN location:
https://svn.mydomain.com/project/branches/build-${SOURCE_BUILD_NUMBER}

But instead checkout from specified branch "build-1.1.50.1-B100" runtime, it's checked from from /trunk.
The build log shows that checkout is from the expected branch, but checking the svn info on workspace claims the code comes from /trunk
