Hello,
thanks for reporting.

Have you tried the option breakBuildIfCausedByExclusion? The exclude option otherwise only affects the reporting, not the breaking of the build.

During investigation I realized that there was an issue with annotation loading of classes. Hence, I fixed this in this context.
