-----------------------------

             Summary: submodule with $revision version can't be referenced by a normal version number
                 Key: MNG-6752
                 URL: https://issues.apache.org/jira/browse/MNG-6752
             Project: Maven
          Issue Type: Bug
          Components: Dependencies
    Affects Versions: 3.6.1
            Reporter: Martin K


In the following example, pp/pom.xml can't reference its parent with a specific version number ("<version>1-SNAPSHOT</version>") - Unless pp1:pp-pom:pom:1-SNAPSHOT is already present in a maven repository, the build will fail.

Maven reads the parent poms and caches them, before resolving $revision. Therefore it just caches the artifact version "${revsion}" and fails to load the local parent pom, if the parent reference does not also use the version "${revision}"

Precondition: Non of these artificats is already present in a local or remote maven repository.
