Thanks for the replies.

I already took a look at the issue on the plugin's github: https://github.com/tbroyer/gwt-maven-plugin/issues/57

Sadly, this was closed and recently labeled with a wontfix, hence me asking for help here :)

My first comment on this issue tells you how to do it. In case it isn't clear, what I meant there is:

<executions>

  <execution>

    <id>compile-module1</id>

    <goals>

      <goal>compile</goal>

    </goals>

    <configuration>

      <moduleName>com.example.module1.Module1</moduleName>

      <moduleShortName>module1</moduleShortName>

    </configuration>

  </execution>

  <execution>

    <id>compile-module1</id>

    <goals>

      <goal>compile</goal>

    </goals>

    <configuration>

      <moduleName>com.example.module2.Module2</moduleName>

      <moduleShortName>module2</moduleShortName>

    </configuration>

  </execution>

</executions>

Another possibility (if you really do want to fork one and only one GWT compiler process) is to use the exec-maven-plugin's exec goal (though you would have to declare your source roots as resources dirs to get your sources copied to target/classes so they're present in the computed <classpath/>).

(I suppose you could get something working by "hacking" into the <compilerArgs>, and probably then <forceCompilation>true</forceCompilation> as you'd have the staleness check only take the module configured in <moduleName>/<moduleShortName> into account; I would discourage such "hack" though)
