How do I make my archetype from a multimodule project use directories that are based on the artifactId? - build-process

Question

I have create an archetype using archetype:create-from-project out of a multi module project.
The archetype-metadata.xml is like below, what I would want is that the "dir" can be modified when I run mvn archetype:generate by using the archetypeId I provide instead of using a fixed dir. Can that be done?
<?xml version="1.0" encoding="UTF-8"?>

This is the structure of the archetype:
├── pom.xml
└── src
├── main
│   └── resources
│   ├── archetype-resources
│   │   ├── pom.xml
│   │   ├── service
│   │   │   ├── pom.xml

You need to use the rootArtifactId placeholder such as :
<?xml version="1.0" encoding="UTF-8"?>
<archetype-descriptor xsi:schemaLocation="http://maven.apache.org/plugins/maven-archetype-plugin/archetype-descriptor/1.0.0 http://maven.apache.org/xsd/archetype-descriptor-1.0.0.xsd" name="service-parent"
xmlns="http://maven.apache.org/plugins/maven-archetype-plugin/archetype-descriptor/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<modules>
<module id="${rootArtifactId}-def" dir="__rootArtifactId__-def" name="${rootArtifactId}-def">
<fileSets>
<fileSet filtered="true" packaged="true" encoding="UTF-8">
<directory>src/main/java</directory>
<includes>
<include>**/*.java</include>
</includes>
</fileSet>
</fileSets>
</module>
<module id="${rootArtifactId}" dir="__rootArtifactId__" name="${rootArtifactId}">
<fileSets>
<fileSet filtered="true" packaged="true" encoding="UTF-8">
<directory>src/main/java</directory>
<includes>
<include>**/*.java</include>
</includes>
</fileSet>
<fileSet filtered="true" packaged="true" encoding="UTF-8">
<directory>src/test/java</directory>
<includes>
<include>**/*.java</include>
</includes>
</fileSet>
<fileSet filtered="true" encoding="UTF-8">
<directory>src/test/resources</directory>
<includes>
<include>**/*.xml</include>
<include>**/*.properties</include>
</includes>
</fileSet>
<fileSet encoding="UTF-8">
<directory>src/test/resources</directory>
<includes>
<include>**/*.sql</include>
<include>**/*.dtd</include>
</includes>
</fileSet>
</fileSets>
</module>
<module id="${rootArtifactId}-web" dir="__rootArtifactId__-web" name="${rootArtifactId}-web">
<fileSets>
<fileSet filtered="true" encoding="UTF-8">
<directory>src/main/webapp</directory>
<includes>
<include>**/*.xml</include>
</includes>
</fileSet>
<fileSet filtered="true" encoding="UTF-8">
<directory>src/main/resources</directory>
<includes>
<include>**/*.xml</include>
</includes>
</fileSet>
</fileSets>
</module>
</modules>
Rename your module folders using the __rootArtifactId__ prefix.
You can see an example of such archetype in http://code.google.com/p/open-archetypes/source/browse/multi-javaee5-archetype/src/main/resources/META-INF/maven/archetype-metadata.xml
