Thanks, the jpl submodule had not updated properly. Now I am getting a new error:

Errors while running CTest
It happens because JUnit 4.11 and above require hamcrest-core.jar in the class path, as shown in this stackoverflow question. I do have it:
$ ls -al /usr/share/java/hamcrest-core.jar
lrwxrwxrwx 21 root 5 Jun 2018 /usr/share/java/hamcrest-core.jar -> hamcrest/core-1.3.jar
but it is not included in the classpath (from the error above):
