Question

I have created a GWT Maven project in Eclipse using New->Project->Maven project->GWT Eclipse plugin. It was created, but it gives some errors like

The output directory for the project should be set to /gwtproject/src/main/webapp/WEB-INF/classes

Is anything missing while configuring my project?

My pom.xml includes:

<build>
        <!-- Generate compiled stuff in the folder used for developing mode -->
        <outputDirectory>${webappDirectory}/WEB-INF/classes</outputDirectory>
        <plugins>

You need to configure the missing part in <webappDirectory> tag in the pom. I think this should solve your problem: Click Here
