I recognise that as Apache is a meritocracy, there is a barrier for other developers getting involved. The Hudson model of "You want commit access, here you go" is a tad too liberal for me, but the Apache model is too far the other way IMHO. To some extend the codehaus model as practiced on mojo seems a good compromise to me... but anyway aside from all that... Maven is hosted on Apache, therefore I feel that core Maven libraries should be hosted on Apache until they have significant adoption elsewhere... the Maven Repository API... well that kind of says it all as far as I'm concerned with respect to where it should live. The Guice changes, well guice is widely adopted elsewhere, so I'm not suggesting that Guice be relocated or forked into apache, but the Maven specific parts of that integration.... hang about... "maven specific" says it all again. I have always had concerns about plexus being pretty much only adopted by Maven as far as I can see, and essentially being a maven core component, except it isn't -Stephen Ralph > > > On Aug 3, 2010, at 8:05 PM, Jason van Zyl wrote: > > > > > On Aug 3, 2010, at 9:52 PM, Brett Porter wrote: > > > >> > >> On 04/08/2010, at 4:21 AM, Jason van Zyl wrote: > >> > >>> Hi, > >>> > >>> We have two major pieces that we, Sonatype, would like to merge into > Maven 3.x trunk. > >> > >> Are these reviewable distinctly?
