GWT, Maven, Spring - Getting com.thoughtworks.qdox.parser.ParseException: syntax error on Maven Build - spring

Question

I am trying to integrate the code from this demo: http://code.google.com/p/gwt-spring-starter-app/ into my main Spring application. I am able to run the gwt-spring-start-app as itself but when I integrate it into an existing Spring app that has a lot of non-GWT classes I am getting the error (on maven build): com.thoughtworks.qdox.parser.ParseException: syntax error
I've spent a while searching on this and seems others have the same problem but I just can't comprehend what they say to do to fix it.. I believe its an issue with the pom and some sort of dependency declaration that shouldn't be there or something but can't figure out what.. I would greatly appreciate if anyone can take a look at the pom below and let me know if you know what could be causing this. Thanks

The /home/user/Desktop/JFDemoGWTFork/src/main/java/org/apache/lucene/queryParser/QueryParser.java is just some apache lib file that I included as source.. from the other posts I found that were sort of for the same issue it seems it will do this for many / all (?) classes that aren't the specific GWT RPC related classes

Answer 1

Change the gwt-maven-plugin version to 2.1.0-1.
