A project can consist multiple modules, where a
module is a project with some dependency on each other.
Create a Parent project: ( which behaves like parent to further maven
modules)
File – New – Other –
Maven Project
Check “Create a
simple Project (Skip archetype selection)
Next
Group id : com.parent
Artifact id : parent
Packaging : POM ß
Finish
This is how pom.xml looks like
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.parent</groupId>
<artifactId>parent</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>pom</packaging>
</project>
Create a child / maven module:
File – New – Other –
Maven Module
Check “Create a
simple Project (Skip archetype selection)
Module Name: Child
Parent Project:
Parent
Finish
This is how pom.xml looks like
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>com.parent</groupId>
<artifactId>parent</artifactId>
<version>0.0.1-SNAPSHOT</version>
</parent>
<artifactId>child</artifactId>
</project>
Observations:
In child pom.xml: observe
that parent tag, which talks about who is my parent
Note: any dependencies declared in parent pom.xml are available to
child pom.xml by default.
Testing:
GO to parent pom.xml
file folder and say > mvn clean
Now two projects will
be created.
