What is the lastest version our test was successfully running with ? 

Did you follow all steps of the migration guide ?

Hello, i got the same issue, but only when using sonar or cobertura maven 
plugins.

Did you already succeed to run gwt-test-util with coverage tools ??

Thanks

This error message wasn't very explicit, so I modified this portion of code to 
have a finer reports in 0.28-SNAPSHOT

By the way, I added cobertura to the pom configuration and the test coverage 
reports are well generated.

Does it work with the lastest snapshot available ?

Hello,
I upgraded to 0.28-SNAPSHOT to figure it out.
So, I got the following issue, but only with sonar (I attached the full trace):

It probably is a classloading issue. I'll try to get gwt-test-utils working 
with sonar before releasing the 0.28 version.

Sonar reports generation is working fine with gwt-test-utils-0.28. It should be 
a configuration problem in your project.

gwt-test-utils documentation has been updated. You should have a look to it. If 
possible, you also may provide your application project so I could check what's 
wrong.

I found the cause, i used the *useManifestOnlyJar* with false value in the
surefire configuration.
It is working now.
