title: How to trigger automatic build in gitlab CI on commit to non-default branch?

  <p>However, when a new branch is created and pushed into repository, build is not sheduled in gitlab CI. What are the settings for enabling build of other branches - alterativaly, how can i figure out what went wrong?</p>
