However, to\r\ncorrectly configure a Scala 2.10 project in Eclipse, the following project's settings need to be set in `.settings/org.scala-ide.sdt.core.prefs`:\r\n\r\n```\r\nscala.compiler.additionalParams=-Xsource:2.10 -Ymacro-expand:none\r\nscala.compiler.sourceLevel=2.10\r\n```\r\n\r\nAnd, of course, we should also make sure that ``scala.compiler.useProjectSettings=true`` is set."}}
