When we go to each build log, as in ...jenkins/job/<job name>/1, we have a list of Changes from Git which identifies the corresponding SHA1 against the changes. However, since Jenkins job configure only gives 1 GitHub project url, and we are using the Multiple Git plugin, the SHA1 attached always refer to the 1 repo, even though it might belong to a different repo.

Example:

repo1
-change 1: SHA1=12345
repo2
-change 3: SHA1=09876

The change list on that page shows

Changes
Git

Changelog updated by ... (commit: 12345) (detail)
Getting gitzip version (commit: 09876) (detail)

When I click on the commit link, they both leads to repo1's commit history. The first link will work because the SHA1 belongs to repo1, the second link will fail
