Cannot import io.druid.math.expr.antlr.*

[Jason Heo]

Hello,

I'm trying to build Druid from source code.

I'm using Intellij CE on Mac.

But I'm facing an antlr issue like this:

I thought this would be occurred because there was only antlr grammar, So I ran `antlr4 -Dlanguage=Java Expr.g4`, But I got a following error.

$ antlr4 -Dlanguage=Java Expr.g4

warning(156): Expr.g4:20:53: invalid escape sequence

warning(156): Expr.g4:25:23: invalid escape sequence

warning(156): Expr.g4:26:21: invalid escape sequence

Exception in thread "main" java.lang.RuntimeException: set is empty

How can I resolve this problem?

Regards,

Jason.
