mvn versions:set not updating child poms

Question

I did much research on this but could not resolve it so far.

I've following structure,

root folder
parent/pom.xml (parent pom)
artifact1/pom.xml
artifact2/pom.xml
pom.xml (aggregator pom)

root/pom.xml
------------

<parent>
    <groupId>releasetest2</groupId>
    <artifactId>root</artifactId>
    <version>1.0.4</version>
    <relativePath>parent</relativePath>
</parent>

<artifactId>aggregator</artifactId>
<packaging>pom</packaging>


artifact1/pom.xml
-----------------

<parent>
    <groupId>releasetest2</groupId>
<artifactId>root</artifactId>
<version>1.0.4</version>
<relativePath>../parent</relativePath>
</parent>

<groupId>releasetest</groupId>
<artifactId>artifact1</artifactId>
<packaging>jar</packaging>


artifact2/pom.xml
-----------------

<parent>
<groupId>releasetest2</groupId>
<artifactId>root</artifactId>
<version>1.0.4</version>
<relativePath>../parent</relativePath>
</parent>

<groupId>releasetest</groupId>
<artifactId>artifact2</artifactId>
<packaging>jar</packaging>


parent/pom.xml
--------------

<groupId>releasetest2</groupId>
<artifactId>root</artifactId>
<version>1.0.4</version>
<packaging>pom</packaging>

<properties>
    <MAIN.version>${project.version}</MAIN.version>
</properties>

<dependencyManagement>
    <dependencies>
        <dependency>
              <groupId>releasetest</groupId>
              <artifactId>artifact1</artifactId>
            <version>${MAIN.version}</version>
        </dependency>
        <dependency>
            <groupId>releasetest</groupId>
            <artifactId>artifact2</artifactId>
            <version>${MAIN.version}</version>
        </dependency>
    </dependencies>
</dependencyManagement>

When I use mvn versions:set while being in parent folder it only updates the parent/pom.xml. I expected it to update root/pom.xml artifact1/pom.xml and artifact2/pom.xml

Is there a way to resolve this?

Answer 1

First please revert version number in the parent pom and make sure that all child poms have the same version.

Then navigate to parent pom directory and execute this command :

mvn versions:set versions:update-child-modules -DnewVersion=<New_Version_Number> -DprocessAllModules
