Does maven2 has api to add and call a plugin in another plugin ?
This question has been asked a couple of times in the past, but
nobody seems
to have an answer.
It's a bad practice, and leads to coupling between plugins which is
bad. We've seen the aftermath of this happening in Maven 1.x.
What we promote is augmenting the lifecycle, or the creation of new
lifecycles to slot in the functionality required.
In 2.0.x it is possible for Mojos in the same plugin to communicate
with one another and in 2.1.x we have a data bus of sorts where
information can be placed on the bus and examined by other plugins
where this information can be keyed off of to do work generally.
If you have a set of plugins that work together then make a lifecycle
given you can control the execution and ordering of the lifecycle
instead of directly invoking Mojos from one another which is
categorically a bad practice. It will lead to coupling and make your
Mojo un-reusable for other use cases i.e. slotting them into other
lifecycles.
So, I think it's fair to conclude that there is no API available
for this.
Or should I spell out dependency on the plugin being called and invoke
Mojo.execute() directly?
You could indeed add the resp. plugin as a dependency and call it
directly,
but how about configuring the plugin's input parameters?
That's a real pain.
An API would be very nice, including some form of Configuration
object to
pass to the plugin.
Cheers
Jo
