mvn-release does not fail early (e.g. GIT_PRIVATE_KEY not set)
Describe the bug
The mvn-release job does not fail early if GIT_PRIVATE_KEY is not set.
Expected behavior
If the configuration is not correct the job should log an error directly fail, so the problem becomes clearly visible.
Actual behavior
An error is logged, but the pipeline continuous and fails later with an unclear error from maven.
