Compile time of refresher is too much

I am refresher add on, compilation is taking too much time 16 mins approx which in turn increasing my build time.

my pom.xml contains:

vaadin-addons http://maven.vaadin.com/vaadin-addons org.codehaus.mojo gwt-maven-plugin 2.1.0-1
            <configuration>
	   <!-- if you don't specify any modules, the plugin will find them -->
  		   <!--modules> .. </modules -->
	   <webappDirectory>${project.build.directory}/${project.build.finalName}/VAADIN/widgetsets</webappDirectory>
	   <extraJvmArgs>-Xmx512M -Xss1024k</extraJvmArgs>
