For some reason, whenever I press runClient lately, I always get this error message:

Exception in thread "main" java.lang.NoClassDefFoundError: cpw/mods/gross/Java9ClassLoaderUtil
    at cpw.mods.modlauncher.TransformationServicesHandler.discoverServices(TransformationServicesHandler.java:139)
    at cpw.mods.modlauncher.Launcher.run(Launcher.java:75)
    at cpw.mods.modlauncher.Launcher.main(Launcher.java:66)
    at net.minecraftforge.userdev.LaunchTesting.main(LaunchTesting.java:105)
Caused by: java.lang.ClassNotFoundException: cpw.mods.gross.Java9ClassLoaderUtil
    at java.net.URLClassLoader.findClass(URLClassLoader.java:382)

    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:355)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:351)
    ... 4 more

Can someone explained why this happens?

Found a way to fix it!

I went to the gradle folder on the right side of the project and press "Reload All Gradle Project" and now I can runClient without the errors showing up!

      Thanks, I've now installed a slightly newer version and the server is at least starting up now.

      The crash points to moonlight lib - try other builds or make a test without this mod and the mods requiring it

      Do you have shaders enabled? There is an issue with the mod simpleclouds - remove this mod or disable shaders, if enabled

      Maybe you need to create file in assets/<modid>/items/<itemname>.json with content like this:   { "model": { "type": "minecraft:model", "model": "modname:item/itemname" } }
