Package: antlr4
Version: 4.5.3-2
Severity: important
Dear Maintainer,
I was trying to view the parse tree for an input sentence via the
/usr/share/antlr4/grun script
that comes with your package. However, grun crashed with the following
exception:
Exception in thread "main" java.lang.NoClassDefFoundError:
org/abego/treelayout/Configuration
I figured out the problem lies in CLASSPATH (set by the grun script) missing
the tree layout
library /usr/share/java/treelayout.jar.
Reproduction steps:
1. Create a grammar, e.g. test.g4:
grammar test;
main: 'hello' ('a'|'b')+;
2. Run "antlr4 test.g4"
3. Compile test*.java
4. Run "/usr/share/antlr4/grun test main -gui"
5. Enter "helloab" followed by an EOF
Potential solution:
CLASSPATH=.:/usr/share/java/antlr4.jar:/usr/share/java/antlr4-runtime.jar:/usr/share/java/treelayout.jar
