ANTLR 4 RuntimeMetaData and Vocabulary

I am using the ANTLR4 IntelliJ plug-in, and I am using a the Antlr-4.5.1 Jar.

When I Generate Antlr Recognizer in Lexer and Parser can't resolve symbols RuntimeMetaData and Vocabulary.

If I use the command line to compile and run my .g4 file it works fine but gives errors in IntelliJ.

I can swap in the command line compiled Lexer and Parser Java files for the error ones and it runs fine.

I'm on Mac OS X 10.11 using IntelliJ 15.

You might have an older antlr4-runtime-x.y.z.jar on your compile classpath. I had the same issue when upgrading the antlr4-maven-plugin to 4.5.1, but forgetting to do the same for the antlr4-runtime dependency.
