How does maven find plugins?

Hi folks,

I'm pretty new to m2 (and maven), but trying to pickup steam.

I ran the xmlbeans:xmlbeans task and it correctly located this plugin 
into my local repository.  I have *no* repositories defined in my pom.xml

However, when I ran the compile phase, (m2 compile), I figured it would 
call xmlbeans:xmlbeans at the generate-sources phase and then run the 
compile phase.

Instead, it failed because it couldn't find the xmlbeans in the maven 
repo on ibiblio (failure shown belown).
Why did running "m2 xmlbeans:xmlbeans" correctly find the plugin?  I've 
not specified the codehaus repo anywhere explicitly.  How come running 
"m2 compile" doesn't find it?

I'm hoping this is a problem with my config or understanding that you 
folks can clarify.

Thanks,

Brian

Re: How does maven find plugins?

Posted by Brian Bonner <br...@paraware.com>.
it turns out there is a problem with the artifact id in maven-xmlbeans.

I logged a jira:  http://jira.codehaus.org/browse/MOJO-76
