Michał Bartczak commented on QDOX-231:
-------------------------------------------

Taken from the current gwt-maven-plugin:

{code}
    <dependency>
      <groupId>com.thoughtworks.qdox</groupId>
      <artifactId>qdox</artifactId>
      <version>1.12</version>
    </dependency>
{code}

I made an example and now I am not 100% sure where the error comes from.

You may try the example that I've attached. Here is what the results would be:

* First run mvn:compile. On target You will see 
generated-sources/gwt/com/demo/gaemaven/client/GreetingServiceAsync.java which 
is fine, the annotation is processed and there is line of code having 
target.setServiceEntryPoint( GWT.getModuleBaseURL() + "blah" );
* Delete that source file
* Rerun mvn:compile, and voila - you get the same class back but this time with 
target.setServiceEntryPoint( GWT.getModuleBaseURL() + "GreetingService" );, 
which is wrong.
* As long as compiled version of interface is in target/classes, all source 
generation will fail
