Brittle solution would be:
val grammarDir = sourceDir / "org" / "apache" / "spark" / "sql" /
"catalyst" / "parser"
antlr.setLibDirectory(grammarDir.getPath)
grammarFileNames.foreach { gFileName =>
// We construct the entire path in order to make sure the file
exists.
val relGFilePath = ((grammarDir / gFileName) relativeTo
sourceDir).get.getPath
log.info("ANTLR: Grammar file '%s' detected.".format(relGFilePath))
antlr.addGrammarFile(relGFilePath)
}
