JBoss has recently migrated its maven repository infrastrucure to Nexus. It is possible that the JBoss OSGi examples that come with the Beta7 distribution do not work for you unless you make some repo adjustments

Here are the details

In case you do not have the (deprecated) artefacts already in you local repository, you need to add this profile to your ~/.m2/setttings.xml

   <profile>
      <id>jboss-deprecated</id>
      <repositories>
        <repository>
          <id>jboss-deprecated</id>
          <name>JBoss Deprecated</name>
          <url>https://repository.jboss.org/nexus/content/repositories/deprecated/</url>
          <layout>default</layout>
          <releases>
            <enabled>true</enabled>
            <updatePolicy>never</updatePolicy>
          </releases>
          <snapshots>
            <enabled>false</enabled>
          </snapshots>
        </repository>
      </repositories>
    </profile>

Now you can run

examples> mvn -Pjboss-deprecated install
