How do I include configuration files with Maven Appassembler?

Unfortunately this is a limitation of the appassembler plugin in the current release version. Typically, the plugin is used in conjunction with the assembly plugin to produce the final artifact, in which you can include the reference to your configuration directory. However, if you'd like to have a functional structure from just the appassembler plugin you need to manually copy the files into place. An example using the antrun plugin with a src/main/conf directory can be found here: http://svn.apache.org/viewvc/archiva/trunk/archiva-jetty/

By default, the plugin uses the directory src/main/config.

Is possible to change the source for the config files using the parameter <configurationSourceDirectory>src/main/config</configurationSourceDirectory>
