Parsing java properties files with Scala

parse_properties.scala

import scala.io.Source.fromFile

def parseProperties(filename: String): Map[String,String] = {
  val lines = fromFile(filename).getLines.toSeq
  val cleanLines = lines.map(_.trim).filter(!_.startsWith("#")).filter(_.contains("="))
  cleanLines.map(line => { val Array(a,b) = line.split("=",2); (a.trim, b.trim)}).toMap
}

you gotta close the file to prevent a leak.
can be split like

                val file = fromFile(filename)
		val lines = file.getLines.toSeq
		file.close()
		val cleanLines = lines.map(_.trim).filter(!_.startsWith("#")).filter(_.contains("="))
		cleanLines.map(
			line => {
				val Array(a,b) = line.split("=",2)
				(a.trim, b.trim)
			}
		).toMap
