I'm trying to install Erlang (and later Elixir) with asdf however I'm getting an error regarding jinterface as the install process seems to freeze:
➜ ~ asdf install erlang 22.1.1

I had a look at https://github.com/asdf-vm/asdf-erlang and it says
For example, to skip the java dependency during installation use:
$ export KERL_CONFIGURE_OPTIONS="--disable-debug --without-javac"
$ asdf install erlang <version>
If I had to guess, this is a java issue so when I try this solution it doesn't work and I get the same output.
Any idea on how to install Erlang this without installing Java? I don't recall this being an issue with Homebrew, meaning Homebrew requiring Java compiler present.
I suspect it's not actually freezing - it's compiling Erlang, but hiding all the output. Give it ten to twenty minutes or so, and it should complete.
You can verify this with top. Compiling Erlang is CPU intensive, so you should be able to easily spot C and Erlang compilers with close to 100% CPU usage.
