Plugin insantiation: once per execution? Once per build?

[Laird Nelson <lj...@gmail.com>]

What is the lifespan of a Mojo?

Is a new one created for each execution?  Is it discarded thereafter, or
does Maven retain a reference to it?

Or is only one created and then reconfigured/reset?

I didn't find any obvious documentation explaining this, but as usual my
apologies if I've overlooked something.

Thanks,
Laird

Right; I want to know what is *intended* versus what I can observe
happening.  Is the intended behavior what happens?  Or can the Maven
developers decide to change the plugin lifecycle out from under me?  IMHO
any plugin system should be governed by a contract.

I'd like my plugin to be as thread-safe as possible, but to do that I need
to know its lifecycle.  Thanks!

Best,

Hi, I suppose that you ask that.because you're writing a mojo yourself. I
don't know the answer but it seems to me it would quite simple to check it
by code: just add a log in your constructor and see if displays once or many
times.

By the way, also think abt "thread-safing" your code to prevent having bugs
using -T switch.

Cheers
