If you do nothing fancy in your plugins then you should be able to migrate to 3 without changes to the plugin. 3.0 is mainly a refactoring of the 2 code and tries to remain as much backwards compatible as is possible. So no, yes, no. 3 will complain if you did not specify versions in the plugins, so that is something to pick up.

We have been using mvn 2.1 for a while and we have understood it fairly well. Recently we decided to move to 3.x,( mainly for teh parallel build feature with the -T switch ) But we find teh documentation difficult to come by. Googling didnt dig up any tutorial or guides for 3.0 specific features. Specifically, we have the following fundamental questions. Will be very grateful if somebody could answer these. 1. I read about the changes for the pom.xml in 3.x. Does that mean that I should change my poms, even if I m not using any features specific to 3.x. ( Maybe I should change the namespace from http://maven.apache.org/POM/4.0.0 to something newer ? ) 2. When I built a simple project, all of teh plugins that got automatically downloaded from http://repo1.maven.org looked pretty much like the plugins used by maven 2.x. Does that mean that most of the plugins and repositories I would be using will be exactly same as maven 2.x ? 3. Even teh super pom looks teh same in maven 3.x ( verified using help:effective-pom ). Are we supposed to oevrride any of teh versions in the superpom for the core plugins, so as to get the ones that would work with maven 3.x ? ( probably to get the latest thread safe versions ? ) Thank you for reading. --sony
