I install antlr in my eclipse. And set antlr-code generator-output folder-project relative folder as antlr-generator.
I can new grammar file (grammar.g)and compile it successfully. There isn't files in the folder (antlr-generator) But files: grammarLexer.java and grammarParser.java are not created.
How can fix this issue?
Just installed Eclipse Indigo and ANTLR 3.4 on Windows 7x64 and had the same problem and no errors on the ANTLR Console. Uninstalled java and installed latest v7 update 4 (32 and 64 bit) and cleaned up classpath and path environment variables. Still no files generated but now I was seeing error "No such directory: org/antlr/tool/templates/dot/dfa" in the ANTLR Console. The fix is in Eclipse under Window, Preferences, ANTLR, Builder, Building. In the General section, make sure that -nfa and -dfa are unchecked. This fixed it for me.
I am not an expert programmer and have yet to write an ANTLR program. Probably others here can figure out how to fix the directory not found error.
I ended up creating this article on configuring ANTLR IDE in case you never go this working or just wanted to check your configuration. And this article on testing/debugging may be helpful also.
