Re: [m2e-users] M2E Extension Development: Help

sourceDirectory antlr/antlr3 mojo configuration parameter defines
location of grammar, i.e. .g, files location. By default sourceDirectory
parameter value is src/main/antlr3 like you mentioned, but it can be
changed to something else in pom.xml, so m2e-antlr configurator makes
sure it watches the right directory.
