I tried doing this and it said "error: could not find or load main class .net.preferIPv4Stack=true"

When i try to install forge with the installer it tells me that libraries can't be found, such as "org.scala-lang.plugins:scala-continuations-library_2.11:1.0.2" and 4 other all in scala-lang. I went and checked and they all have the proper .jar files in them so i don't know why it's not working
