>
> With the move to antlr 4.5.3, the antlr4-maven-plugin gives a "No grammars to
> process" message during "mvn clean package" if *.tokens files have previously
> been generated. Using previously generated tokens files can lead to
> unexpected behavior (see comments from
> https://github.com/apache/incubator-systemml/pull/243).
> The tokens files can be deleted during the "initialize" maven lifecycle phase
> so that they will be regenerated during the "generate-sources" maven
> lifecycle phase (that the antlr4 goal binds to).
