Multiverse Core not found

Can someone take a look at this and tell me why it might not be confirming the multiverse plugin as an instance of multiverse. I can't figure it out

private void loadMultiverseCore() {
    Plugin multiversePlugin = getServer().getPluginManager().getPlugin("Multiverse-Core");
    if (multiversePlugin instanceof MultiverseCore) {
        MVWorldManager = ((MultiverseCore) multiversePlugin).getMVWorldManager();
    } else {
        throw new RuntimeException("Multiverse-Core not found!");
    }
}

private void loadMultiverseCore() {
    Plugin multiversePlugin = getServer().getPluginManager().getPlugin("Multiverse-Core");
    if (multiversePlugin instanceof MultiverseCore) {
        MVWorldManager = ((MultiverseCore) multiversePlugin).getMVWorldManager();
    } else {
        throw new RuntimeException("Multiverse-Core not found!");
    }
}

I have the 4.3.1 API and MultiverseCore-4.3.1 installed and running on my server yet it still tells me it's not found. Not sure what it is

EarthCowOP•2y ago

I forked it The jar on the spigot page loads multiverse fine but there's errors when using the plugin so I thought I would just update it but I can't get multiverse as an instance of the class

Lunaiskey•2y ago

well thats just weird

EarthCowOP•2y ago

bro it's so annoying thanks for you guys trying to help though I appreciate it

Lunaiskey•2y ago

doesnt multiverse have a discord? ask there if they do

QarthO•2y ago

whats ur plugin.yml look like?

Lunaiskey•2y ago

id assume exactly like the github

EarthCowOP•2y ago

yes except I added Multiverse-Core as a depend

depend:
  - Multiverse-Core

depend:
  - Multiverse-Core

QarthO•2y ago

so this is how they're doing it now not using instanceof

mvCore = (MultiverseCore) this.getServer().getPluginManager().getPlugin("Multiverse-Core");
// Test if the Core was found, if not we'll disable this plugin.
if (mvCore == null) {
    Logging.severe("Multiverse-Core not found, disabling...");
    this.getServer().getPluginManager().disablePlugin(this);
    return;

mvCore = (MultiverseCore) this.getServer().getPluginManager().getPlugin("Multiverse-Core");
// Test if the Core was found, if not we'll disable this plugin.
if (mvCore == null) {
    Logging.severe("Multiverse-Core not found, disabling...");
    this.getServer().getPluginManager().disablePlugin(this);
    return;

EarthCowOP•2y ago

I can try it but doesn't casting require it to be of that type?

QarthO•2y ago

thats why ur checking it with the if im looking at other addons and this is how they're doing it

Lunaiskey•2y ago

well if that returns null then itll try and cast null

EarthCowOP•2y ago

who are you referring to btw

EarthCowOP•2y ago

I'm not trying bro

private void loadMultiverseCore() {
        MultiverseCore mvCore = (MultiverseCore) this.getServer().getPluginManager().getPlugin("Multiverse-Core");
        // Test if the Core was found, if not we'll disable this plugin.

bruh

QarthO•2y ago

its fine hmm idk tbh

EarthCowOP•2y ago

same I'm stump

QarthO•2y ago

maybe try importing the multiverse plugin directly instead of using pom adding it as a resource

EarthCowOP•2y ago

I can try that but idk how that'll change anything

QarthO•2y ago

yeah i dont think it will either.. LMAO im stumped too

EarthCowOP•2y ago

java.lang.ClassCastException: class com.onarandombox.MultiverseCore.MultiverseCore cannot be cast to class com.onarandombox.MultiverseCore.MultiverseCore (com.onarandombox.MultiverseCore.MultiverseCore is in unnamed module of loader 'Multiverse-Core-4.3.1.jar' @6c663e50; com.onarandombox.MultiverseCore.MultiverseCore is in unnamed module of loader 'MultiverseHardcore-2.0.0.jar' @5a6b6814)

this error confuses me Conflicting classes?

Lunaiskey•2y ago

thats like its trying to create a new instance or smth join the mv discord

QarthO•2y ago

i found this exact issue in the mv discord

QarthO•2y ago

Lunaiskey•2y ago

ohhhh they didnt shade mv core

EarthCowOP•2y ago

mines already set as provided 😭

Lunaiskey•2y ago

open the jar with recaf or jdgui or smth and check if it hasnt included it

EarthCowOP•2y ago

nah tf I thought the provided was going to be it I tried reloading maven and shit and fresh building but it still fails also if there was a class conflict wouldn't I be able to see a duplicate in the jar?

Lunaiskey•2y ago

uhh that means you have implemented it it shouldnt be there post your pom.xml

EarthCowOP•2y ago

it was originally implemented and then I changed it to provided is there something I have to do additionally? pom.xml I FOUND IT lemme make sure it works first thank you I wouldn't have known

Lunaiskey•2y ago

you found what?

EarthCowOP•2y ago

Lunaiskey•2y ago

EarthCowOP•2y ago

the multiverse core jar file was listed where I circled after I removed it It wasn't in the jar anymore like you said and it worked

Lunaiskey•2y ago

that would do it

EarthCowOP•2y ago

alr but I didn't put it there

Lunaiskey•2y ago

its why you never touch the project structure

EarthCowOP•2y ago

it must've happened when maven was set to implement and then when I changed it to provided it never removed the jar I never fuck with that dw thanks for all your help guys !solved
