Qooxdoo code is compiled using python script provided with the SDK.
There are few receipe to build qooxdoo apps using maven, but I rolled up my own, and I share it with you, because I think it is hasslefree. You even don't need to install python if you want!
This is possible thanks to jspresso maven repository that hosts the latest qooxdoo-sdk releases
I'm a maven newbee, so please help me make theses pom.xml snipets simplier or standard.
Let's begin.
Repository
First you need to specify the jspresso repository.
<repositories>
<repository>
<id>jspresso.org</id>
<url>http://repository.jspresso.org/maven2/</url>
</repository>

Plugin
During the compile phase, It fetches jython (Python on the JVM)
Then extracts jython.jar and the Lib directory from the jython-installer.jar
After that, it updates jython.jar (it adds the Lib directory to the jython.jar so it contains all the necessary stuff to compile qooxdoo).
On next compile, it won't do this long process again, since it checks for the existence of the file before fetching it from the Internet.
During the clean phase, it removes all the created files and directories.
As you can see, I've used maven-antrun-plugin since I'm more familiar with ant.

Dependencies
In the dependency part, the only needed thing is qooxdoo-sdk :
<dependencies>
<dependency>
<groupId>org.qooxdoo</groupId>
<artifactId>qooxdoo-sdk</artifactId>
<version>1.4.1</version>
<type>zip</type>
</dependency>
<!-- ... -->
</dependencies>
Profiles
The most interesting part is happening in the profiles.
This is where we unpack the qooxdoo-sdk, and we compile the qooxdoo code.
Qooxdoo code is compiled from src/main/qooxdoo and the compiled code will end up in
target/qooxdoo.
The pom.xml file allow two different way of invoking the qooxdoo compiler, one with "native" python. The other one using the jython we downloaded, using jython to compile is a lot slower, but it is convenient since there is nothing more to install.
If you wish to build the qooxdoo code using native python, you need to download and install it. You will notice that it is a lot faster to compile the qooxdoo source code this way. BEWARE Python 3 is not supported, 2.5+ required.
Here is the profile to build using native python. It activates when you pass -DbuildQooxdoo=true.
You can specify where to look for the python executable if it is not in the PATH.

Using this pom.xml snipets you should be up and running in a minute!
As I write this post, I notice that I could do better by invoking getJython in the qooxdoo-building-jython profile only. This is one improvement I see, but you will probably spot more than one!
Happy Qooxdooing!
