I'm following the documentation of gwt-maven-plugin along with the one on the Google Web Toolkit Blog to have a GWT project mavenized but without success.
Using eclipse 3.6, I create a new maven project using the archetype gwt-maven-plugin 2.1.0-1
I followed instructions found here Google Web Toolkit Blog but it doesn't work. I'm getting an exception:
java.lang.NoClassDefFoundError: com/google/appengine/tools/enhancer/Enhance Caused by: java.lang.ClassNotFoundException: com.google.appengine.tools.enhancer.Enhance at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) Exception in thread "main"
I'm using gwt 2.2.0 in GAE 1.4.2 on google eclipse plugin. The same version numbers are used in my pom.xml
Here is the the pom.xml that was generated. It uses 2.1.0 version of gwt but I changed it manually to 2.2.0
