Unable to build buck. Java class file version error.

[ljubinkovicdj93]

Description

I've cloned the repo but I'm unable to build buck. There was an identical issue: #2355 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 buck command with the following:

  Buck encountered an internal error

I'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:
