How to delegate the execution to other Mojos?

[Gajo Csaba <cs...@cosylab.com>]

Hello,

I would like to create a maven plugin, which would delegate to other 
plugins based on parameters. Something like mvn mymojo:dotask -Dtask=<xxx>

and then in the "dotask" mojo I would see what the value of task is, and 
if it's xxx then execute Mojo1, if it's yyy then Mojo2 etc...

How can I do this?

Thanks, Csaba

I would suggest that maybe profiles would be better suited... if you specify
the defaultGoal in the profile it gets even easier...

But to be honest, you are going against *The Maven Way™*

This is usually (but not always) a sign that you will soon be fighting
Maven, and that is a fight that you can only win with the loss of all of
your hair ;-)

OK so my use case would be

mvn do-task -Dtask=xxx

Do you suggest I change that into

mvn do-task-xxx?

Short answer: Don't

Long answer: for a mojo to extend another maven plugin, it will need
to depend on that maven plugin.  The maven plugin classloader only
loads a plugin once, and the first version loaded is the version used
forever more (until maven exits).  When a newer version of the plugin
you depend on is released, you will either force the older version on
anyone using your plugin, or the newer version will be forced on you.
In either case, the build will probably be broken in a hard to figure
out way
