Echoing execution phase with a Mojo

[Raúl Arabaolaza Barquín <ra...@mundivia.net>]

Hi:

I�m developing a pluging to echoe it�s execution phase to console, in the Wiki FAQ this is one unanswered question so i tried it out by myself.

I believed that by using the MojoDescriptor i could get it (javadocs are not too complet) but i�m having a NullPointerException when trying to retrieve the MojoDescriptor:

Im using the mojo�s goal as parameter for the PluginDescriptor.getMojo() method, but i�m not sure if this is a correct use of the API. If not, could anyone give me a hint about the correct use of the getMojo method?.

Another problem i�m facing is that the phase binding of my mojo is not working unless i explicity set a execution tag in my pom, i don�t need to specify a execution phase, but i need a goal for my plugin to execute.

I Attach both my Mojo and the plugin.xml generated file.

Thanks
