Greetings. I am trying to install minecraft 1.12.2 forge (forge-1.12.2-14.23.5.2860) but after I press "Install client," the green progress bar loads for a while, and soon as the green progress bar is full, an error message pops up and says... "These libraries failed to download. Try again. org.scala-lang:scala-compiler:2.11.1" Does anybody know what is going on? Please let me know. Thank You Best Regards
