Hi,
I found a solution to this problem after reading this page :
http://docs.codehaus.org/display/MAVENUSER/Assembly+Plugin
Modification for the main project (important part is the executions block) :
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<inherited>true</inherited>
<configuration>
<descriptors>
<descriptor>${basedir}/assembly/livraison.xml</
descriptor>
</descriptors>
</configuration>
<!-- important part is here -->
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>assembly</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</pluginManagement>
</build>
Important : Now, with this configuration, you must launch "mvn ... package"
and not "mvn .... assembly:assembly"
Bye
