CI Workflow Runs are failing

[adil-hussain-84]

I created a pull request earlier today. The CI Workflow Run for this pull request (here) appears to have failed for a reason unrelated to my change.

This is what I see in the build log:

building jre_emul.jar
building jre_emul-src.jar
building json.jar
make[1]: *** [/Users/runner/work/j2objc/j2objc/jre_emul/build_result/json.jar] Error 2

Usage: javac <options> <source files>

make: *** [jre_emul_jars_dist] Error 2
make: *** Waiting for unfinished jobs....
Error: Process completed with exit code 2.

Pay attention to the javac: invalid source release: 11 line in the build log.

The latest CI Workflow Run for the master branch appears to have failed for the same reason. See the build log here.

The problem is most likely caused by the JAVA_HOME environment variable on the build machines. It is set to JDK 8 and not JDK 11. See Issue #2115 for more information about this.

Can somebody who has access to the build machines please change the JAVA_HOME environment variable to JDK 11 🙏

Fixed in PR #2168.
