[jvm-packages] two xboost4j installation issues


I’ve been following the documentation step by step and have been repeated tripped up at the ‘mvn package’ step where errors prevent me from installing xboost4j completely. For reference, I’m running Java 1.8.0_212, Maven 3.6.1, and the latest version of CMake downloaded from the cmake site on a Mac with OS X 10.11.6. Now there’s a set of errors that I’ve been running into, that I’m going to post below in order:

Now I’ve made sure that my $JAVA_HOME is correctly set up and that both Java and Maven are in my PATH, and manually checked for the jni.h file within the include subfolder of $JAVA_HOME to make sure it is there. I’ve tried running mvn with and without sudo. I’ve put the correct CC and CXX tags within config.mk . I can’t tell if this is a jni.h/$JAVA_HOME issue or if there’s something with my cmake that’s making these errors happen because both errors appear. And I’m not sure how to resolve either of these issues. Could someone shed some insight or point me in the right direction?
