Symptoms
When integrating clover into your build, the build fails with duplicate class errors:
Cause
The jaxws-maven-plugin adds the output directory for the generated sources to the compile source roots. Clover changes the ${project.build.sourceDirectory} to target/clover/src-instrumented when it performs the instrumentation, thus maven ends up having both the original generated code and the instrumented code on the compile path.
Resolution
Configure the jaxws-maven-plugin to use ${project.build.sourceDirectory} as the <sourceDestDirectory>.
