Tapestry 5.3 之後捨棄了Maven (個人還是覺得應該繼續用Maven)，使用Grandle工具類似Maven， 現在尚未有時間理解它。
Then, how to Build?
- brew install gradle
- svn checkout https://svn.apache.org/repos/asf/tapestry/tapestry5/trunk tapestry-project
- cd tapestry-project
- gradle idea (create a project file for Intellij Idea)
- gradle install
