Try gwtSdkFirstInClasspathtrue/gwtSdkFirstInClasspath in your gwt-maven-plugin configuration.

Had the same problem. Problem was because of presence of another JdtCompiler (those one with Tomcat in my case) in class path which was run instead of GWT's one.

Hi Thomas, thanks for the reply. I found that the problem is with this dependency... dependency groupIdorg.jibx/groupId artifactIdmaven-jibx-plugin/artifactId version1.2.5/version /dependency And using gwtSdkFirstInClasspathtrue/gwtSdkFirstInClasspath did solve the compile error. But why does this happen, I only use the jibx classes on the server ?? I did read your suggested posts, but in my case I would like to keep the GWT in one module.I have several modules, and actually two gwt apps, wanted to keep the modules down to a minimum. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
