This project simplifies development of maven based GWT projects. The idea is to replace gwt-servlet jar dependency by dependency from war artifact containing gwt-servlet library. This way gwt-servlet library is not added to the classpath of maven projects, not confusing the IDE which would show some GWT classes twice otherwise.
In order to use this project with maven just put the following snippets in your pom.xml (which has packaging set to war):
pl.ncdc.gwt gwt-servlet-war 2.3.0 war
gwt-servlet-war-release http://gwt-servlet-war.googlecode.com/svn/maven2/
