Hello, I’m having this exact same issue. Where do I insert the line of code that you shared? Should I be looking for a JavaComplie file? Or is this something you add to gradle-wrapper.properties or some other file related to the program installation.
For some extra info, I’m using gradle to build the newest version of Picard, but I keep getting the same warnings above. The build finishes “successfully” but when I run the tests, I get a failed test.
