Add license to package

[Cris Rockwell]

I’m trying to build a JCR package using maven. The config below builds the 
package, but I also get an error related to verify-legal-files

[ERROR] Failed to execute goal 
org.codehaus.mojo:ianal-maven-plugin:1.0-alpha-1:verify-legal-files 
(verify-legal-files) on project org.apache.sling.auth.saml2.example: Artifact

-> [Help 1]

      <filter>
        <root>/apps/sling/saml2</root>
      </filter>
    </filters>
  </configuration>
</plugin>

How can the license be added to the JCR package?
