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

             Summary: Continuous Delivery friendly versions do not work on root pom's parent
                 Key: MNG-6438
                 URL: https://issues.apache.org/jira/browse/MNG-6438
             Project: Maven
          Issue Type: Bug
         Environment: Apache Maven 3.5.3 (3383c37e1f9e9b3bc3df5050c29c8aff9f295297; 2018-02-24T20:49:05+01:00)
Maven home: /usr/local/Cellar/maven/3.5.3/libexec
Java version: 1.8.0_162, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.8.0_162.jdk/Contents/Home/jre
Default locale: en_DE, platform encoding: UTF-8
OS name: "mac os x", version: "10.13.5", arch: "x86_64", family: "mac"
            Reporter: Konrad Windszus


If I use either {{${revision}}},{{${sha1}}}, or {{${changelist}}} in the root pom's parent version it simply does not work, even when the project is invoked via 
{{mvn package -Drevision=1.0}} and the according parent is available in version {{1.0}} in my Maven repo.
Instead I get the following error
{code}
mvn package -Dsha1=1.0
