java.lang.NoClassDefFoundError: org/w3c/dom/ElementTraversal

2. When compiling tomcat:

...
[INFO] Caused by: java.lang.NoSuchMethodError: org.eclipse.jdt.internal.compiler.ast.MessageSend.binding()Lorg/eclipse/jdt/internal/compiler/lookup/MethodBinding;

Answer 1

The gwt compiler caches certain things. Could some things be hanging around from your 2.7 build?

Do a clean build, to remove the /gwt-unitCache folder.

Also in the temporary directory (on Linux /tmp) check for gwt* folders and delete them all.
