When creating a pipeline build none of the options allow environment variables. The documentation I found at https://jenkins.io/doc/pipeline/steps/atlassian-bitbucket-server-integration/ states that the branch name should be able to use environment variable, however, it doesn't appear to mark it up.

Hard Coded Example:

branches: [[name: 'branchname']]

Results:

Produces a scan just on branch with name 'branchname'

Environment Example 1:

branches: [[name: '${ENV_VARNAME}']]

Result:

Produces a scan of all branches in all the repoisotry

Environment Example 2:

branches: [[name: '${env.ENV_VARNAME}']]

 Result:

Stack Exception
