We don't bundle all the dependencies inside our jars. This is akin to static linking. Do this instead.

$ java -cp $(java-config -d -p antlr-4) org.antlr.v4.Tool

Or better still, just call /usr/bin/antlr4. This does the same thing in a smarter way, as it also considers whether your selected JVM will work.
