JUCA 1.3 just has been released. The main change is that I abandoned ANT and switched to maven.
Besides JUCA, two additional projects have been created: a maven plugin, which calls JUCA during the site goal, and an example project, which can be analyzed with JUCA and a demo report can be created.
Subversion URL of the maven plugin: http://source.valtech.com/svn/repos/juca/maven
Subversion URL of the example project: http://source.valtech.com/svn/repos/juca/juca.example
For backward compability reasons, former JUCA XML configuration files can be reused. Alternatively, the maven-juca-plugin can be configured directly in the POM, but as long as the former JUCA XML configuration file can be found, it takes precedence - so be aware!
