java.lang.ClassNotFoundException: wtf.zani.launchwrapper.LunarLaunchWrapperKt

[catfromplan9]

followed README, tried v1 branch since documentation hasn't been updated, got this

java.lang.ClassNotFoundException: wtf.zani.launchwrapper.LunarLaunchWrapperKt

Exiting with ERROR

I have edited customjar.json to the one in README, no dice. I also tried the precompiled jar on the releases page. I pick "Replace minecraft jar" in prism version tab for instance.

[catfromplan9]

This really should be documented better, but I had to "customize" the default jar (not the one i'm replacing) then edit net.minecraft.json

Now:

java.lang.Exception: Failed to fetch manifest. Response: {"success":false,"error":{"code":"outdated_launcher","short":"Outdated Launcher","message":"Your launcher is outdated. You must re-download at lunarclient.com/download to continue."}}
	at wtf.zani.launchwrapper.version.VersionManifest$Companion.fetch(VersionManifest.kt:201)

I assume v2 branch fixes this but there is no documentation on how to use that in prism

[catfromplan9]

issue on v2

Fixed it, no idea how you did not encounter this issue, PRing now

[catfromplan9]

Even more problems with your code, what sort of sorcery did you pull to get this to work on your computer?? I cannot fathom how so many issues would occur for me in code that works for you. Anyway, I'm fixing them.

[catfromplan9]

I have hit a wall, not sure how to fix this one

Fixed it, no idea how you did not encounter this issue

The field exists when trying to launch under Windows and v2 hasn't had a chance to be tested under Linux yet.

now im somehow getting [WebSocketConnectReadThread-181/ERROR]: [LC IPC] WS-Error: Connection refused?

Is there something on your system blocking connections to authenticator.lunarclientprod.com or websocket.lunarclientprod.com?

Fixed with adding --add-opens java.base/java.lang=ALL-UNNAMED to java command before -cp, but this should be fixed

This will be properly documented in future. Sorry about that.

Nope. Theres also some errors about contacting mojang session server. I confirmed it works fine in another instance and by visiting the websites in my browser, and problem is reproducible. Try testing it yourself.
