SNS messages with same branch name in global pipeline library do not trigger pipeline

[ccureau]

Scenario

Our global pipeline library code is stored in a CodeCommit repository. It has a number of branches matching release* and a master branch.

The microservice pipeline is configured to trigger based on an event on the release branch in another CodeCommit repository. It has branches named release and master.

The SNS trigger is set to send notices for any change to the repository for any branch.

Expected Behavior

When a new branch release appears in the microservice repository, or when a commit is made to the release branch, the pipeline should trigger and build the microservice.

Actual Result

The trigger logic searches not only the microservice repository, but also the global pipeline repository for changes to the release branch. Because the global pipeline code has not changed, the pipeline is not triggered.
