Hi Rick,
it depends which maven plugin you are talking about. m2eclipse I assume.
Have you tried browsing their mailing list:
http://www.nabble.com/Maven-Eclipse---User-f14525.html
You can use a standard maven heirarchical directory layout, but eclipse
will not allow you to create a project for the parent project - but
you're only missing out on the parent pom - it's no big deal.
however the bigger issue is that the m2eclipse plugin won't compile the
jar. You still need to run that from the command line.
you could try a flat layout by referring to the child modules like this:
<module>../hello</module>
but I haven't tried it.

I'm trying to set up a project from scratch using Maven 2 and Eclipse
3.2. I'm starting by working with the Quick Start to understand how a
project with multiple modules should be structured to accommodate both
systems.
I understand that while Eclipse 3.2 now supports sub-projects, the Maven
plugin doesn't. I tried to follow the example in Better Builds with
Maven, but it looks like the J2EE example switches between flat and
hierarchal layouts.
Here are the POM files that I have. When I select External Tools
compile or package, I get BUILD SUCCESSFUL but no class files or jar is
written to the target directory.
So what is the correct way to lay out a project that will consist of
multiple modules?
eclipse\workspace\hello-world\pom.xml
<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>com.accessrxs.hello</groupId>
<artifactId>hello-world</artifactId>
<packaging>pom</packaging>
<version>1.0-SNAPSHOT</version>
<name>Maven Quick Start Archetype</name>
<url>http://maven.apache.org</url>
<modules>
<module>hello</module>
</modules>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>

</dependencies>
</project>
eclipse\workspace\hello-world\hello\pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0";

<parent>
<groupId>com.accessrxs.hello</groupId>
<artifactId>hello-world</artifactId>
<version>1.0-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>hello</artifactId>
<packaging>jar</packaging>
<name>Maven Quick Start Archetype submodule</name>
</project>
Thanks, Rick DeBay
