You should not use the emma plugin, as it integrates Emma, which hasn't been updated in nearly a decade. Even though it wasn't updated, it continued to work for years.
Eventually, it was succeeded by EclEmma, which eventually re-based itself on JaCoCo (Java Code Coverage).
So now, you want the jacoco plugin, which has been updated to keep pace with Java Generics, and with the new functional interfaces.
