Arctoris Posted June 8, 2018 Share Posted June 8, 2018 So I am in the process of making my own modpack Come across a new hurdle, and was wondering if I could get some help as nothing online can explain this to me. I see you usually ask for pastebin logs so I will provide one https://pastebin.com/GHG6ZZhj Link to comment Share on other sites More sharing options...
Moderators Munaus Posted June 9, 2018 Moderators Share Posted June 9, 2018 (edited) this doesn't belong in Bug Reports, as this is not a bug with the Launcher. Moved to Platform Pagoda for discussions about custom modpacks Exception in thread "main" java.lang.NoSuchMethodError: joptsimple.OptionParser.allowsUnrecognizedOptions()V it's impossible to tell what this error is. post your link to the modpack so others can see how you set it up Edited June 9, 2018 by Munaus Link to comment Share on other sites More sharing options...
