Using Jenkins 2.138.3 and Subversion plugin on a windows machine. When doing a checkout from SVN server, SVN_REVISION environment variable isn't available as when trying to get the value all it return is empty string.

I have tried to use ${SVN_REVISION} & ${SVN_REVISION_1} but none of them return any revision number.

As suggested on stack overflow tried downgrading to subversion 2.10.3 but it still didnt work.

Additionally,
After i downgraded SVNPlugin and then updated it again i now manage to get the SVN revision being set.

However if i have an external set for the SVN repository i cannot access the external repository using SVN_REVISION_2
SVN_REVISION_1 now returns the revision of teh actual repository.
