<!­­ Before adding ANYTHING in here, please start a discussion on the dev list.
Ideally the Axis2 build should only use Maven central (which is available
by default) and nothing else. We had troubles with other repositories in
the past. Therefore configuring additional repositories here should be
considered very carefully. ­­>
