This error shows up when I'm tring to bind my library, seems to be caused by deprecated java version

gomobile: javac -d /tmp/gomobile-work-2528798080/javac-output -source 1.7 -target 1.7 -bootclasspath /home/starx/Android/Sdk/platforms/android-33/android.jar go/Seq.java go/Universe.java go/error.java spaceship_aar/Config.java spaceship_aar/LauncherWrapper.java spaceship_aar/Spaceship_aar.java failed: exit status 2

For anyone else who might run into this issue.

Make sure that the system installed gomobile tooling, and the gomobile dependency in your project are BOTH up at the latest version (or pinned to compatible versions).
