Error to execute goal Maven-GWT-Mojo - eclipse

Question

I'm trying configure my Eclipse (Kepler), when I execute Run as -> Maven Clean, that works. After I execute Run as -> Maven Install, this error below is showed in console.
There's a solution? Thanks for attention.

Try to match your pom.xml with below one that is used for GWT compile.
There may be some issue in source or class path or war directory location.
Note: Replace versions and EntryPointClassName in below configuration and change the JAVA version to 1.7 also

<testSourceDirectory>src/main/test</testSourceDirectory>
