My question above was not as precise as it should have been, sorry.
What I meant was: after having done
$ mkdir /tmp/antlr-test
$ cd $_
$ wget --page-requisites --recursive --level=inf --convert-links \
--no-parent \
https://www.cs.cornell.edu/courses/cs4120/2013fa/handouts/antlr.html
$ cd www.cs.cornell.edu/courses/cs4120/2013fa/handouts/xi
$ antlr4 XiLexer.g4 XiParser.g4 -no-listener
why was it not sufficient for me to do
$ javac Xi*.java
i.e. why was it instead necessary for me to do
$ CLASSPATH='.'
$ CLASSPATH+=':/usr/share/java/stringtemplate4.jar'
$ CLASSPATH+=':/usr/share/java/antlr4.jar'
$ CLASSPATH+=':/usr/share/java/antlr4-runtime.jar'
$ CLASSPATH+=':/usr/share/java/antlr3-runtime.jar/'
$ CLASSPATH+=':/usr/share/java/treelayout.jar"
$ javac -cp "$CLASSPATH" Xi*.java
and does that necessity mean that there is a bug in the antlr4 package
on Stretch?
Thanks again,
Sam
