Repo, gerrit & Jenkins co-working

Question

I have a problem with getting Google's Repo, gerrit & Jenkins working together.

our setup:

we have a Repo build out of few git repositories, which are all on our gerrit server. Manifest is also there.

Workflow:

• user do changes in few files which sits in different git repositories in the Rep.

• user commit & push the changes to Code review.

Problem:

• for each of the repositories, a separate gerrit code review is created.

• For each of those code reviews, Jenkins is being triggered.

If the changes are inter-depended (which they usually do), the Jenkins build will fail, as it takes only the changes in one repository each time.

How do we make Jenkins/Gerrit co-op to get the full changes into one build (that will work)?

Thanks

The configuration described here is very problematic,
and is sure to cause you grief in the future as well.

In the long run, consider one of those paths:

• Reduce dependency between the components to the minimum
  (this is preferred)
• Merge the code to a single repository

Meanwhile -

• Make sure the verification-job (in Jenkins) checks-out the latest code from all the other repositories
  (those that are relevant for building this change)
• Make (non-breaking) changes to one repository at a time
  (requires some planning, of course)
