The modules of a multi-module project are aggregated from a hierarchical structure.
The root pom
packing should look like:
<packaging>pom</packaging>
The following will be the directory structure of the project:
|-- sample-app
\ `-- pom.xml
|-- sample-module-1
| `-- pom.xml
|-- sample-module-2
| `-- pom.xml
Root POM:
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>com.sample</groupId>
<artifactId>sample-app</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>pom</packaging>
<modules>
<module>sample-module-1</module>
<module>sample-module-2</module>
</modules>
<dependencyManagement>
...
</dependencyManagement>
</project>
