ERROR: Tag must follow the pattern '^:[a-zA-Z0-9_]([a-zA-Z0-9_.-]){0,127}' (for private registry with port)

      After upgrade docker commons plugin 1.17 -> 1.21 we got this error:

      ERROR: Tag must follow the pattern '^:[a-zA-Z0-9_]([a-zA-Z0-9_.-]){0,127}'

      Found few similar issues, but no resolve for our case. We use private docker registry with custom port example.com:6050. Probably, additional ":" cause error. Example, to reproduce:

      def DOCKER_REPO = 'example.com:6050'
def DOCKER_REPO_APP_DEV = "${DOCKER_REPO}/project/app"
def SOME_ARG = "test"

...
        stage('Build and Push Images') {
          environment {
              GIT_COMMIT = "`git rev-parse HEAD`"
          }
          steps {
            script {
              docker.withRegistry("https://$DOCKER_REPO", 'RegistrySecret') {
                def image_app = docker.build("${DOCKER_REPO_APP_DEV}:${GIT_COMMIT}", "--build-arg SOME_ARG=$SOME_ARG -f Dockerfile .")
                image_app.push()
                image_app.push("latest")
              }
            }
          }
        }
...

      On 1.17 version this example works, but on 1.21 - don't.

       

      Regards.
