I receive an error after launching a Jenkins pipeline, but right at the SCM step, configure via the plugin (not by the groovy).

The message refers to a "Name" wrong spelled, but I can't figure out to which of my fields it is referring.

I looked to the source code, but it manipulates a concatenation of several inputs...

This is a git SCM.

Jenkins interface

ERROR: Name must follow the pattern '^[a-zA-Z0-9]+((.|_|__|-+)[a-zA-Z0-9]+)*$'

The stack trace contains org.jenkinsci.plugins.docker.commons.credentials.ImageNameValidator, so this error is for Docker image name validation, not your Git SCM.

  • Thanks, we have an image name generated from a Jenkins parameter. It seems that this feature is now disabled (security issue, I guess). So a ${abc} is refused by the ImageNameValidator. It is painful that the error message doesn't display the string analysed.

  • I could think the problem was the consequence of a security patch not allowing me to inject a docker image name in a variable, but it's that the regex only accepts ' and not "... I think this could be patched in Jenkins code.
