This task only invokes JavaCC if the grammar file is newer than the generated 
Java files. javacc assumes that the Java class name of the generated parser 
is the same as the name of the grammar file, ignoring the .jj. If this is not 
the case, the javacc task will still work, but it will always generate the 
output files. 

So, rename either your .jj file, or the output class, so that their names 
match, and then the <javacc> task will only generate the parser when it is
