Maven's set version plugin doesn't set parent version in child module

Question

While I was trying to automate the version updates of all the poms in the project, I couldn't fix this issue. The versions:set plugin/command does replace almost every version of a pom but not the versions of the parent pom (another project) defined in the parent part of the pom.xml itself.

<parent>
    <groupId>com.test.app</groupId>
    <artifactId>helloWorld</artifactId>
    <version>3.19.0-SNAPSHOT</version>
    <relativePath />
</parent>

<groupId>com.test.app.child</groupId>
<version>3.21.0-SNAPSHOT</version>
<artifactId>helloWorldChild</artifactId>
<name>${project.groupId}::${project.artifactId}</name>
<packaging>pom</packaging>

As you can see the two versions are different. This is after I executed the following command:

mvn versions:set -DgroupId=com.test.app.* -DartifactId=* -DoldVersion=* -DnewVersion=3.21.0-SNAPSHOT

The expected result is, that both, an all versions versions are 3.21.0-SNAPSHOT instead of 3.19.0-SNAPSHOT. Is there any possibility to fix this?

Your version and group should come from the parent, they should not be set in the child, only the artifact should be set in the child.

<parent>
    <groupId>com.test.app</groupId>
    <artifactId>helloWorld</artifactId>
    <version>3.19.0-SNAPSHOT</version>
    <relativePath />
</parent>

<artifactId>helloWorldChild</artifactId>
<name>${project.groupId}::${project.artifactId}</name>
<packaging>pom</packaging>

Unfortunately our project doesn't allow this for several reasons. Still any ideas how to fix it? – TheKara Feb 14 '18 at 14:35

they're the rules of maven, you are breaking them, this is the way multi module projects work – Essex Boy Feb 14 '18 at 14:38
