</project>Using Excludes and Includes
Sometimes you may want to process some grammar files before others. In this case the <includes> and <excludes> configuration options can be used. In the example below, all files in the source directory that end with -step-1.jj will be processed by JavaCC, and then all other .jj files will be processed.
