Issue with release-start goal creating multiple release branches

[jelingi]

When executing the release-start goal of the Gitflow Maven Plugin in Jenkins, it appears that the remote check is not executed correctly. Even if there is already an existing release branch, running the release-start goal again results in the creation of a new release branch, instead of thowing the error "Release branch already exists. Cannot start release."

GitFlowReleaseStartMojo.java:153-157
final String releaseBranch = gitFindBranches(gitFlowConfig.getReleaseBranchPrefix(), true); if (StringUtils.isNotBlank(releaseBranch)) { throw new MojoFailureException("Release branch already exists. Cannot start release."); }

Plugin Version: 1.20

If I execute the command in the Pipeline :
sh "git for-each-ref '--format=%(refname:short)' refs/heads/release/** refs/remotes/origin/release/**"

All the refs are shown correctly:

• git for-each-ref '--format=%(refname:short)' 'refs/heads/release/' 'refs/remotes/origin/release/'
  origin/release/17.8.x
  origin/release/18.0.x
  origin/release/19.0.x

Do you have any ideas why the check for existing remote branches isnt working correclty in the plugin ?

Kind regards
