Re: GWT 2.5.1-rc1 available

This happens if you have an older version of a gwt-x library in your classpath. 

It actually happened to me because the gwt-bootstrap version I used had a dependency to an old gwt-codeserver-1.5.0.jar version.  This dependency was removed in a latter gwt-bootstrap snapshot. 

Run  mvn dependency:tree -Dverbose on your gwt app and check if there any references to an older gwt version. 

Regarding gwt-maven plugin. Yes it is still version 2.5.0 but you can use newer GWT SDKs (http://mojo.codehaus.org/gwt-maven-plugin/user-guide/using-different-gwt-sdk-version.html)

I deleted all my target/war directories, but it is still not working.  I don't have an easy way to compile with eclipse.  I will wait until there is a gwt maven plugin and try again.  Thanks.

Deleting gwt-unitCache solved the issue for me. I have also deleted war/<appname> and war/WEB-INF/deploy but I think thats not needed.

Can you compile through Eclipse using GPE? I don't think the maven plugin itself is causing the problem. Maybe you still have a gwt-unitCache folder lying around somewhere that you haven't found/deleted yet?

I tried upgrading from 2.5.0 to 2.5.1 but I am getting an error during the gwt compile.  I googled that I needed to remove my gwt-junitCache, which I tried but it doesn't seem to be helping.  I am still using the 2.5.0 gwt maven plugin since the 2.5.1 is not available.  Could that be causing the problem?  Thanks.
