We will not be using any maven archetypes/templates but do it by hand to get a project that is as clean as possible.

First create a directory that will contain all the modules the ear file consists of. It will contain all the basic info the other projects/modules need to inherit from.

Create the pom.xml file in the directory and update it with something like the following:

<?xml version="1.0" encoding="UTF-8"?>
<project
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
	<modelVersion>4.0.0</modelVersion>
	<groupId>your.group.id</groupId>
	<artifactId>your-artifact-name</artifactId>
	<packaging>pom</packaging>
	<name />
	<version>0.0.1-SNAPSHOT</version>
	<description />
	<modules>
		<module>ear</module>
		<module>war</module>
		<module>ejb-jar</module>
	</modules>
	<build>
		<plugins>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-compiler-plugin</artifactId>
				<configuration>
					<source>1.5</source>
					<target>1.5</target>
				</configuration>
			</plugin>
		</plugins>
	</build>
</project>

Then create the subdirectories ( I named them ear, war and ejb-jar in this case ) for the modules.

ejb-jar pom.xml:

<?xml version="1.0" encoding="UTF-8"?>

war pom.xml:

This is basically the project structure. I hope to create a downloadable archetype of this structure so you can start with this by running the mvn archetype plugin for easy use.
