<!-- 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
