Building Cocoon 2.2
Get Cocoon 2.2 from trunk
Do svn checkout http://svn.apache.org/repos/asf/cocoon/trunk of Cocoon trunk. Keep up-to-date because there is everyday improvement.

mvn clean install
This will build the core artifacts (sitemap, pipelines, blocks-fw, etc.) and the most important blocks. If you want to build Cocoon completely, call
mvn install -P allblocks
which activates the allblocks profile.
If you run into problems, check the page on solving common Maven2 problems.

However, after doing 'svn update' you will need to let Maven loose on the network again. When doing active development, it is a good idea to add the "clean" goal to be sure that everything gets rebuilt.
