How to change jar packaging into pom packaging in Java project

Question

I have a single Java Maven project having a pom.xml with jar packaging. Now I want to add a sub-project in that project. So, I need to change the packaging pom from jar.

<groupId>org.test.app</groupId>
<artifactId>testPom</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>jar</packaging>

Please provide any suggestion.

Answer 1

This would be the parent POM part with packaging and a couple of module references:

<groupId>org.test.app</groupId>
<artifactId>testPom</artifactId>
<packaging>pom</packaging>
<version>1.0-SNAPSHOT</version>

<modules>
    <module>submodule</module>
    <module>another-submodule</module>
</modules>

Hope it helps.
