CircleCI should have such an example, I commented that over there

Thanks!

Quick question, anyone knows how to use different branches with base-revision on this?

@ryanpedersen42

what happens if i have two paths for one variable? will it set the variable if either path is modified? e.g.

            project1/.* project-one true 
            shared-things/.* project-one true

            project1/.* project-one true 
            shared-things/.* project-one true

Yes!

Thanks!

@ryanpedersen42

use base-revision for different actions based on branch.
you can only specify only one branch per job
