Maven ear plugin & ejbModule with classifier - maven-2

Question

In my maven2 multi-modules project I have 2 modules
one with an ejb3
one for the ear
The ejb contains dependencies that I want to include into the jar.
So for the ejb my pom.xml is
<?xml version="1.0" encoding="UTF-8"?>
<project

</build>
Two jars are well generated
[INFO] [install:install {execution: default-install}]
[INFO] Installing ...\cendo2015\modules\ejb\target\cendo2015-ejb-1.0.jar to ...\.m2\repository\be\tuto\cendo2015-ejb\1.0\cendo2015-ejb-1.0.jar

I now want to include the jar-with-dependencies into the ear.
So my ear pom.xml is
<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">

</parent>

<dependency>

<artifactId>cendo2015-ejb</artifactId>
<classifier>jar-with-dependencies</classifier>
</ejbModule>
</modules>
</configuration>
</plugin>
</plugins>
</build>
And finally, my parent pom.xml is
<project

Running mvn clean package gives me
[INFO] [ear:generate-application-xml {execution: default-generate-application-xml}]
[INFO] ------------------------------------------------------------------------
[ERROR] BUILD FAILURE
[INFO] ------------------------------------------------------------------------
[INFO] Artifact[ejb:be.tuto:cendo2015-ejb:jar-with-dependencies] is not a dependency of the project.
Now if I do a mvn clean package only for the ear module, it's working.
[INFO] [ear:ear {execution: default-ear}]
[INFO] Copying artifact [ejb:be.tuto:cendo2015-ejb:jar-with-dependencies:1.0] to [cendo2015-ejb-1.0-jar-with-dependencies.jar]
So I don't understand what's happening !
