maven3 on 64 bit Ubuntu 11.10

Here is a maven3 PPA that worked fine for me on 64 bit Ubuntu 11.10

sudo add-apt-repository ppa:natecarlson/maven3
sudo apt-get update && sudo apt-get install maven3

If you have maven2 already installed from canonical repos this will not replace it but give you a mvn3 binary.

If you prefer to have the binary called mvn instead of mvn3 you can simply do the following:

sudo ln -s /usr/bin/mvn3 /usr/bin/mvn

mvn eclipse:eclipse 後記得！！！

設定  M2_REPO = /oooxxxx/oooxxx/.m2/repository

or eclipse 中 JAVA - Build Path - Classpath Variable 加上 
M2_REPO = /oooxxxx/oooxxx/.m2/repository
