Unable to build buck. Java class file version error.
Description
I've cloned the repo but I'm unable to build buck. There was an identical issue: #2355 (closed) which got closed.
Steps to reproduce
- Clone the repo and build with
ant:
$ git clone --depth 1 https://github.com/facebook/buck.git
$ cd buck
$ ant- Fails when executing the
./bin/buck build --show-output buckcommand with the following:

... 17 moreI've tried compiling with java 8, 11 and 18... 8 and 11 pass, although when trying to build buck with java 8 it says:
Warning: JAVA_HOME is set to "/Library/Java/JavaVirtualMachines/jdk1.8.0_341.jdk/Contents/Home", which looks like a Java 8 path, but Buck requires Java 11. Ignoring JAVA_HOME. Set BUCK_RESPECT_JAVA_HOME to 1 to disable this behavior.
ant command fails when using java 18 with the following:
