Create a multi module Maven archetype

It can be very helpful to dispose of a library of pre-configured projects. Here, we want to create a multi-module project composed of a core (Hibenate Dao) and a web (SpringMVC webapp) module.

<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/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>net.stephou</groupId>
<artifactId>parent</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>pom</packaging>
<name>parent</name>
<url>http://maven.apache.org</url>

<modules>
 <module>core</module>
 <module>web</module>
</modules>
...

Use a mvn archetype:create-from-project to create the archetype project.
and in target/generated-sources/archetype/ use a mvn install.

In the end, into a new directory, the mvn archetype:generate -DarchetypeCatalog=local will allow you to use the project as a ready-to-code project 🙂

D:\documents\NetBeansProjects>%M2_HOME%\bin\mvn archetype:generate -DarchetypeCa
