Same here

When used antlr4-maven-plugin and dependency antlr4 in pom.xml version 4.5 (current version), errors are different. I used cygwin for the compilation.

UPDATE: When quotes are removed in line 42 in file Rust.g4, and also __LOG is replaced with LOG everywhere, another errors appear:

[ERROR] error(156): xidcont.g4:762:15: invalid escape sequence
[ERROR] D:\projects\rust-netbeans-master\src\main\antlr4\xidcont.g4 [762:15]: invalid escape sequence
...

I found the issue here: https://github.com/antlr/antlr4/issues/276. I am not familiar with ANTL4, but I tried to play with it so I had to remove all statements in files xidstart.g4 and xidcont.g4 beginning with \U.... Then the grammar is finally processed and code compiles well.

However, there are other errors:

Hi All, thanks for the investigation and sorry about the delay. I've been in the process of replacing the ANTLR-based lexer/parser with a native one that uses the Rust compiler directly. It's in master now, and works well on OSX (the main OS I develop on). It also compiles properly on Linux (a step forward, at least!). Unfortunately it doesn't seem to load the native component on Linux properly (see #7). I'll keep investigating, and aiming to get it running on Linux. If anyone is able to work out why the native component is not loading properly on Linux, I'd love to hear from you! Meanwhile, I'll close this issue (the ANTLR issue is solved) and track any progress on #7.
