Artifact [...] is not a dependency of the project

[newbie_tw]

I encounter a new problem whilst following the sample programme at 
http://cwiki.apache.org/GMOxDOC20/very-simple-entity-ejb-example.html. I run 
the command 'mvn compile' it issues the error "Artifact [...] is not a 
dependency of the project." 

After searching the google, someone says that it can be amended by adding tag 
type at http://www.mail-archive.com/users@maven.apache.org/msg33078.html. For 
example, "<type>ejb</type>". Whilst another page 
(http://jira.codehaus.org/browse/MNG-1562?page=com.atlassian.jira.plugin.system.issuetabpanels:changehistory-tabpanel)
 reports that as a bug then it has been fixed in the later version 2.0.7. 
However, I still obtain the same error.

My file structure looks similar the second one.

I have 

pulication folder resided at  the top-most dir. The file structure looks like 
follow:

publication 
    +---[publication-ear]
    +---[publication-ejb]
    +---[publication-war]

the pom.xml which describes plugin looks like follow:

                    <artifactId> maven-ear-plugin </artifactId>
                    <configuration>
                                    <displayName> Sample EAR for publication 
</displayName>
                                    <description> Sample EAR for publication 
</description>
                                    <version>5</version>
                        <modules>
                                          <ejbModule>
                                <groupId>net.sf.sample</groupId>
                                <artifactId>publication-ejb</artifactId>
                                
<bundleFileName>publication-ejb-1.0-SNAPSHOT.jar</bundleFileName>
                            </ejbModule>
                            <webModule>
                                <groupId>net.sf.sample</groupId>
                                <artifactId> publication-war </artifactId>
                                <contextRoot>/publication</contextRoot>
                                
<bundleFileName>publication-war-1.0-SNAPSHOT.war</bundleFileName>
                            </webModule>
                        </modules>
                    </configuration>

How to solve this problem?

I appreciate any suggestion.

Thank you very much.
