Programatically compiling a grammar

[NoahTheDuke]

I'm working on a Clojure codebase that will make use of the java output by antlr4. It's a little awkward to either make two calls (one to compile the grammar, one to compile the .java into .class files) or rely on a justfile to perform those in sequence whenever I modify the grammar. I'd love to be able to add antlr4 as a dev dependency and then call in normal Clojure code the antlr compiling in the same call I use for compiling the java code.

Is this possible? I couldn't find anything in the docs about calling antlr from within java directly.
