> {no format}
>
> $ ./gradlew -p sdks/java/extensions/sql cleanCompileJavacc compileJavacc

> > Task :beam-sdks-java-extensions-sql:compileJavacc
>
> Java Compiler Compiler Version 4.0 (Parser Generator)
>
> (type "javacc" with no arguments for help)
>
> Warning: Bad option "-grammar_encoding=UTF-8" will be ignored.
> \{no format}
> This is simply due to the fact, that this option does not yet exist in JavaCC
> 4.0 [2]
>
> So we probably should just remove this option.
