It works on my Fedora 33. I think you might have some errors in
the classpath, I used the following command:
$ javac -cp
.:/usr/share/java/antlr4/antlr4.jar:/usr/share/java/antlr4/antlr4-runtime.jar:$CLASSPATH
Hello*.java
Thanks! Indeed I had missing `antlr4` dir in my classpath.
$ hello javac -cp /usr/share/java/antlr4/antlr4-runtime.jar Hello*.java
$ hello javac -cp /usr/share/java/antlr4-runtime.jar Hello*.java
$ hello javac -cp /usr/share/java/antlr4-runtime.jar Hello*.java
$ java -version
openjdk version "11.0.10" 2021-01-19
OpenJDK Runtime Environment 18.9 (build 11.0.10+9)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.10+9, mixed mode, sharing)
Same here.
Why is this .jar not added to classpath automatically during installation of `antlr4-runtime`?
