Hi, This is a problem caused by scala's jdk compatibility. we can see from: here

JDK 11 requires minimum 2.11.12, but we set scala version to 2.11.6 in pom.xml because our development are all based on JDK 8. To solve this, whether you could set your JDK to 8, or you could modify scala.version to 2.11.12 in the pom I mentioned above. I would suggest the first option, because that would be the same as our dev&test environment. For second option, I succeeded building the jar, but I didn't run full tests on it.

Thanks. I set my JDK to 8 and that solved my problem.
