How to pass ${CHANGES} to downstream job?

Question

I have upstream job that polls SVN for changes. If changes are detected, the build is started. After the build, the upstream project calls downstream project to run test.

Answer 1

I saw a All Changes Plugin which updates the changes page. Don't know if $Changes gets populated with that info as well.

If that doesn't work, have a look at Get access to Build Changelog in Jenkins
