ANTLR4 Development - where is the current build? And where is the CodeGen?
wish...@gmail.com
I have some questions in regards to the development of ANTLR4.
First of all the JAR is not located where the docu (https://github.com/antlr/antlr4) mentions it. - This might be an issue if you got the ANTLR4 Reference and well... no ANTLR4
http://www.antlr4.org/download/antlr-4.0-rc-1-complete.jar
Now building ANTLR4 with Maven currently fails, and I attached a longer Error log... Mainly I'm interested in fixing the broken C# CodeGen for Unicode String escapes (directly in ANTLR4 so that people can take advantage of it). I wonder whether I need to patch ANTLRworks though.
Best,
Marius

I updated the wiki article "Building ANTLR 4 with Maven" with the latest instructions:
http://www.antlr.org/wiki/display/ANTLR4/Building+ANTLR+4+with+Maven
ANTLR 4 currently only includes a Java target. I'm working on documentation for integrating ANTLR 4 code generation into Ant and Maven builds, which is the only option I recommend (or personally even consider) for projects using ANTLR 4 grammars. ANTLRWorks 1.5 does not support ANTLR 4. The next release of ANTLRWorks 2 (tentatively Beta 1) supports code generation with ANTLR 4 in limited scenarios.

okay now the files are up (the wiki-server gave a 404). I guess this information makes me do the C# (3,4) code-gen later, when the ANTLRworks2 beta is more capable. I hope it's going to be OpenSource btw.. Java CodeGen is not useful for me/us.
I hope the ANTLRworks 1.x Maven build (using Windows or Linux) will succeed and make me patch the Unicode bugs asap.
Best,
Marius
