Hello guys, I'm trying to run a Minecraft Forge server, but I can't launch the file forge-1.12.2-14.23.4.2705-universal.jar. It doesn't even show anything. I found something in a log and down below there is an error from launching via cmd log [17:42:03] [Server thread/INFO]: Starting minecraft server version 1.12.2 [17:42:03] [Server console handler/ERROR]: Exception handling console input java.io.IOException: Neplatný popisovač at java.io.FileInputStream.readBytes(Native Method) ~[?:?] at java.io.FileInputStream.read(Unknown Source) ~[?:?] at java.io.BufferedInputStream.read1(Unknown Source) ~[?:?] at java.io.BufferedInputStream.read(Unknown Source) ~[?:?] at sun.nio.cs.StreamDecoder.readBytes(Unknown Source) ~[?:?] at sun.nio.cs.StreamDecoder.implRead(Unknown Source) ~[?:?] at sun.nio.cs.StreamDecoder.read(Unknown Source) ~[?:?] at java.io.InputStreamReader.read(Unknown Source) ~[?:?] at java.io.BufferedReader.fill(Unknown Source) ~[?:?] at java.io.BufferedReader.readLine(Unknown Source) ~[?:?] at java.io.BufferedReader.readLine(Unknown Source) ~[?:?] at nz$2.run(SourceFile:100) [minecraft_server.1.12.2.jar:?] [17:42:03] [Server thread/INFO]: Loading properties [17:42:04] [Server thread/INFO]: Default game type: SURVIVAL [17:42:04] [Server thread/INFO]: Generating keypair [17:42:04] [Server thread/INFO]: Starting Minecraft server on *:25565 [17:42:04] [Server thread/INFO]: Using default channel type [17:42:04] [Server thread/INFO]: Preparing level "world" [17:42:05] [Server thread/INFO]: Loaded 488 advancements [17:42:06] [Server thread/INFO]: Preparing start region for level 0 [17:42:07] [Server thread/INFO]: Preparing spawn area: 5% [17:42:08] [Server thread/INFO]: Preparing spawn area: 11% [17:42:09] [Server thread/INFO]: Preparing spawn area: 18% [17:42:10] [Server thread/INFO]: Preparing spawn area: 25% [17:42:11] [Server thread/INFO]: Preparing spawn area: 30% [17:42:12] [Server thread/INFO]: Preparing spawn area: 35% [17:42:13] [Server thread/INFO]: Preparing spawn area: 41% [17:42:14] [Server thread/INFO]: Preparing spawn area: 49% [17:42:15] [Server thread/INFO]: Preparing spawn area: 57% [17:42:16] [Server thread/INFO]: Preparing spawn area: 64% [17:42:17] [Server thread/INFO]: Preparing spawn area: 72% [17:42:18] [Server thread/INFO]: Preparing spawn area: 79% [17:42:19] [Server thread/INFO]: Preparing spawn area: 86% [17:42:20] [Server thread/INFO]: Preparing spawn area: 93% [17:42:21] [Server thread/INFO]: Done (17,013s)!
