Hey folks!

I have a noob question. I'm trying to follow the very basic step in https://javacc.com/home/

git clone https://github.com/javacc21/javacc21.git
cd javacc21
ant

I'm getting a compile error in that last ant step (see below). May I get some help to resolve this? I am using a pretty fresh installation of Linux and Java and maybe I missed out something. This is my Java version

$ java --version
