        <!-- Plugin to compile the g4 files ahead of the java files
           See https://github.com/antlr/antlr4/blob/master/antlr4-maven-plugin/src/site/apt/examples/simple.apt.vm
           Except that the grammar does not need to contain the package declaration as stated in the documentation (I do not know
        why)
           To use this plugin, type:
             mvn antlr4:antlr4
           In any case, Maven will invoke this plugin before the Java source is compiled
