### Problem description
I current have 2 jobs for 2 different Gitlab projects. Both are set up to be triggered via webhook, listening to merge request and notes hooks. They both work perfectly well and they update build status on Merge requests.
My current issue happens with trying to build the projects manually. The job is not parametrized and when triggering manually I just want to build master + post the commit status on the master branch.
One of those projects can be built manually and it successfully posts the commit status to the master branch, while the other fails to commit status updates with an error related to missing Build action in gitlabCommitStatus retrieveGitlabProjectIds (Show in Jenkins log above).
How would I go on about fixing an issue like that? I've compared the build.xml files of both projects and they're the same. I can post more info as needed
