K3 is an action language build on top of the Xtend programming language in order to use it for executable metamodeling.

Its key feature allows to "re-open" classes of an Ecore metamodel and to weave new features or operations in these classes.

Please have a look to http://diverse-project.github.io/k3/ for more details and tutorials.

Folders named *-eclipse contains Eclipse-based projects that can be built directly in eclipse or using maven/tycho. Other folders contain pure maven projects. All root folders contains a *.root project that allows to build all the projects in one maven command.

The documentation is in the gh-pages branch.

The annotation processor logs some message using java.util.logging.Logger

One may display more detailed messages by setting the system property java.util.logging.config.file to point to a logging.properties file such as https://github.com/diverse-project/k3/tree/master/resources/logging.properties

Ex: for maven: add -Djava.util.logging.config.file=<locationofpropertiesfiles>
