Found the solution. Since im using 1.12.2 and not one of the newer versions of minecraft the book should be created in a different location (assets.modid.patchouli_books)

Hello all, I've been working on trying to add a guide book to my mod, but have run into a few problems. I am using patchouli and followed the getting started process for modders but still do not get the item in-game when i test it. When I load the game there is only the other item added by my mod and the default guide book from patchouli. Im lost and not sure what to do next. I have already tried following the example books but was not able to get that to show up in-game either. Any help is appreciated.

Fixed it, reinstalled Java completely.

I am creating a server for myself and a bunch of friends to play on, but i cannot get it to work. I have tried fresh installs of forge and different versions of 1.10.2 and nothing has worked . It gives me this when I try to start it. A problem occurred running the Server launcher.java.lang.reflect.InvocationTarge tException at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Nativ e Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(Unknow n Source) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(Un known Source) at java.base/java.lang.reflect.Method.invoke(Unknown Source) at net.minecraftforge.fml.relauncher.ServerLaunchWrapper.run(ServerLaunc hWrapper.java:62) at net.minecraftforge.fml.relauncher.ServerLaunchWrapper.main(ServerLaun chWrapper.java:31) Caused by: java.lang.ClassCastException: java.base/jdk.internal.loader.ClassLoad ers$AppClassLoader cannot be cast to java.base/java.net.URLClassLoader at net.minecraft.launchwrapper.Launch.<init>(Launch.java:34) at net.minecraft.launchwrapper.Launch.main(Launch.java:28) ... 6 more Press any key to continue . . . Thanks for any help. Edit: I tried different versions of forge entirely(1.12 and 1.11) and those also game me the same startup error.
