tried java8parser but build fails

[jc01rho]

i've used this grammar https://github.com/antlr/grammars-v4/tree/master/java/java8

Failing Builds.

and following tutorials, but build fails.

src/ASAI/grammar/cpp_src/sa_java8_translator.h:8:10: fatal error: Java8BaseVisitor.h: No such file or directory
 #include "Java8BaseVisitor.h"
          ^~~~~~~~~~~~~~~~~~~~
compilation terminated.

actually Java8BaseVisitor doesnt created when

java -jar ../../../antlr-4.8-complete.jar  -Dlanguage=Cpp -visitor -no-listener -o cpp_src Java8Lexer.g4
java -jar ../../../antlr-4.8-complete.jar  -Dlanguage=Cpp -visitor -no-listener -o cpp_src Java8Parser.g4

but creates Java8ParserBaseVisitor.h Java8ParserBaseVisitor.cpp

Manual code fix

so i've edited sa_java8_translator.h:8:10 from

include "Java8BaseVisitor.h"

to

include "Java8ParserBaseVisitor.h"

java8ParserBaseVisitor.h:15 from class java8ParserBaseVisitor : public java8BaseParserVisitor { to class java8ParserBaseVisitor : public java8ParserVisitor {

and then looks build and install completly well

but NameError: name 'sa_java8_cpp_parser' is not defined occurs.

what should i do?
