How to add a jar file to a ear with Maven?

How to add a jar file to a ear with Maven
                        Hello!

I have a small ejb-app in a project (my_child_project).
But when I try to build the ear I do not manage to get it inside.
Bellow is my 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/xsd/maven-4.0.0.xsd";>

        <artifactId>my_parent_project</artifactId>
        <version>1.0</version>
        <relativePath>../my_parent_project/pom.xml</relativePath>
    </parent>

    <artifactId>my_child_project</artifactId>
    <packaging>jar</packaging>

    <name>my_child_project</name>

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.0.2</version>
            <configuration>
                <source>1.5</source>
                <target>1.5</target>
            </configuration>
        </plugin>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-ejb-plugin</artifactId>
            <configuration>
                <ejbVersion>3.0</ejbVersion>
                <jarName>my_child_project_jar_server</jarName>
                
<outputDirectory>${project.build.outputDirectory}</outputDirectory>
                <generateClient>true</generateClient>
            </configuration>
        </plugin>
        <plugin>
            <artifactId>maven-ear-plugin</artifactId>
            <configuration>
                <finalName>my_child_project_ear_server</finalName>
                <modules>
                    <jarModule>
                        <groupId>home</groupId>
                        <artifactId>my_child_project</artifactId>
                    </jarModule>
                </modules>
            </configuration>
        </plugin>

    </plugins>
    </build>
</project>


When I run:
mvn clean install
...I get:
 my_child_project.jar

When I run:
mvn ejb:ejb
...I get:
 my_child_project_jar_server.jar
 my_child_project_jar_server-cleint.jar


But when I try:
mvn ear:generate-application-xml
...or...
mvn ear:ear

I get an error about
[INFO] Artifact[jar:home:my_child_project] is not a dependency of the project.

It seems like Maven does not like to put the project it self into the ear?

Any comments is most welcome!
Best regards
Fredrik
