Building the Source
SwingX relies on Maven for controlling compilation, building docs, testing, etc. You can use our POM files to build the project, some IDEs can directly invoke Maven for you.
To compile from the command line, you'll need to have Apache Maven 3.x installed; see http://maven.apache.org.
You can build SwingX by going to the command line and typing mvn package
That should be it--this will test and build swingx.jar in the target directory.
