Antlr4 maven plugin cannot find grammar files in different directories

Question

I\'m using the antlr4 maven plug-in to build my maven project which uses antlr4:

     org.antlr
     antlr4-

I had the same problem and solved with the following configuration:

${basedir}/src/main/antlr4/yourGrammarDirectory
