<build> 
    <outputDirectory>${project.build.directory}/${project.build.finalName}/WEB-INF/classes</outputDirectory> 
    <pluginManagement> 
     <!-- other plugins here --> 
     <plugin> 
      <groupId>com.google.appengine</groupId> 
      <artifactId>appengine-maven-plugin</artifactId> 
      <version>1.9.12</version> 
      <configuration> 
       <enableJarClasses>false</enableJarClasses> 
      </configuration>
