Hello, I'm trying to build a Java 11 Spark distro using the dev/make-distribution.sh script. I have set JAVA_HOME to point to JDK11 location, I've also set the java.version property in pom.xml to 11, effectively also setting `maven.compile.source` and `maven.compile.target`. When inspecting classes from the `dist` directory with `javap -v`, I find that the class major version is 52, which is specific to JDK8. Am I missing something? Is there a reliable way to set the JDK used in the build process?
Thanks, Szymon K.
