When I try to set a Jenkins Global Property DOCKER_REPO and use that value for the Docker Image in a Docker Template, $ {DOCKER_REPO}
/myimage, the following exception is found in the jenkins system log. The expected behavior is that this global configuration parameter is expanded to its string value, and is used as part of the image name.
java.lang.IllegalStateException: The template variable 'DOCKER_REPO' has no value
