The compiler exited abnormally (2) due to a bug in the compiler

[baberrehman]

I have been trying to compile the Ceylon program on my Ubuntu 18.04 machine. Unfortunately I have not been very successful in that. I am using JDK 1.8.0_252. The compiler is exiting with the following error:

Ceylon compile: invalid source release: 11
Usage: ceylon compile
use --help for a list of possible options
ceylon compile: Fatal error: The compiler exited abnormally (2) due to a bug in the compiler.
Please report it:
https://github.com/ceylon/ceylon/issues/new
Please include:

• a description of what you were trying to compile.

Thank you!
