Warning: not deleting branch 'hotfix-XXX' that is not yet merged to

[koenverwimp]

Since a while we get this error when finishing a hotfix branch. Do you know what could be the root cause? It worked before, but we might have updated to a new versions of your plugin.

[ERROR] Failed to execute goal com.amashchenko.maven.plugin:gitflow-maven-plugin:1.20.0:hotfix-finish (default-cli) on project helm-whs: hotfix-finish: warning: not deleting branch 'hotfix-24.6.9' that is not yet merged to

It looks to be a duplicate for #350

Ah i now see that it is related to the fact that we use a SNAPSHOT on the hotfix branch. The plugin does the version change before merging it to master, and create a commit on the hotfix branch. The git command that you do for removing the branch complains about having a hotfix branch locally that is not in sync with the origin because of this 1 commit, and doesn't want to delete the branch.

So related to this property: useSnapshotInHotfix

Anything we can do about this?
