I want to change the standard gwt war output directory to my existing target directory ( it looks like by default it is src/main/webapp where i also have the sources). For that i changed the the source output folder in project properties -> java build path to degx/target/degx-0.0.1-SNAPSHOT/WEB-INF/classes . But i got nullpointerexception

  [ERROR] [degx] Unable to load module entry point class consi.degx.client.Application (see associated exception for details)
java.lang.NullPointerException: null

I also get this error in eclipse : Description Resource Path Location Type The output directory for the project should be set to /degx/src/main/webapp/WEB-INF/classes degx Unknown Google Web App Problem .

But the whole idea is to have the GPE use my already created war target directory using maven. So setting the output directoy to /degx/src/main/webapp/WEB-INF/classes would make GPE not use the directory i want

EDIT1: And i notice that once i set the source output directory to degx/target/degx-0.0.1-SNAPSHOT/WEB-INF/classes , the degx/target/degx-0.0.1-SNAPSHOT/WEB-INF/classes dissappears in project explorer. It only reappears if i change the setting for output source back to its default /degx/src/main/webapp/WEB-INF/classes folder .
