Eclipse Oxygen.3a Release 4.7.3a Maven

I have a project, with a lot of classes.

I tried to create an Antlr4 grammar, so I have my .g4 file on src/main/java/antlr4/mygrammar.g4.

Antlr4 does not generate generate anything.

My pom.xml:

                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

What am I missing? Do I need to invoke manually something?

I have my .g4 file on src/main/java/antlr4/mygrammar.g4.

The ANTLR4 maven plug-in expects the grammars to be in src/main/antlr4, not src/main/java/antlr4.
