@Mojo(name="jtb-javacc", defaultPhase=GENERATE_SOURCES, threadSafe=true) public class JTBJavaCCMojo extends AbstractJavaCCMojo

Preprocesses ordinary grammar files (*.jtb) with JTB and passes the output to JavaCC in order to finally generate a parser with parse tree actions.

Note: JTB requires Java 1.5 or higher. This goal will not work with earlier versions of the JRE.

2.4
