How to disable build trigger with new branch creation

Question

After bamboo spec enablement for repo, any time someone creates a branch on the server, it immediately triggers a build. Even without any commits or code changes. Can we avoid building until an initial commit is pushed?

Before, Bamboo Spec enablement this was working as expected.

Must be buildNumber, not buildnumber (linux example)

Hello @ananda3

Thank you for providing more details on your request.

Bamboo will trigger a build by default on a Plan Branch creation. There is a Feature Request that covers your scenario, but unfortunately, that is still collecting votes for future implementation. We recommend you vote and watch that FR so you get notified once it move forward on its implementation.

* BAM-12944 - Set "Repository triggers the build" but builds still happen automatically on every branch create

As a workaround, you can add a single script task at the top of the very first Stage of your Plan that will exit if it's the first time the build is happening.

Windows:

if ( ${bamboo.buildNumber} -eq 1 ) {
  $host.ui.WriteErrorLine("First build on branch killed to avoid unnecessary build")
  exit 1
}

Linux:

if [ ${bamboo_buildNumber} -eq 1 ] ; then
  echo "First build on branch killed to avoid unnecessary build"
  exit 1
fi

As a result, the first run after creating a branch will fail immediately and you will avoid unnecessary work.

Sincerely,

I think this is not matching with the problem statement, we want to have new branch created but don't want to trigger the build with just new branch creation. We want build to be triggered when there is a commit in the created branch.

Currently, whenever a branch is getting created, it triggers the build in that plan branch.
