PanelStudio: ClassNotFoundException when clickgui gets initialized

``Hello, i’m having an issue when trying to initialize the clickgui,i think its a gradle problem. everything works fine on the runClient task but when trying to initialize the client from the jar in the minecraft launcher it crashes with this error: https://pastebin.com/wdqdxha0 This is my build.gradle file:

It works fine in runClient task with panelstudio and it shows up correctly but when building it to jar and launching it it crashes with this error, i checked and deleted the clickgui, then rebuilt the jar and launched and it worked fine again so its probably an issue caused by me importing uncorrectly panelstudio from gradle. would be awesome if you could help me
