Mod loading fails with java.lang.StringIndexOutOfBoundsException

Posted September 24, 20222 yr

I am pretty new to modding and I cant get my mod to load. Minecraft wont load and it keeps giving me this error java.lang.StringIndexOutOfBoundsException: begin 0, end -1, length 11

@Mod("testmod")
public class testmod {
    private static final DeferredRegister<Block> BLOCKS = DeferredRegister.create(ForgeRegistries.BLOCKS, "testmod");

    public static final RegistryObject<Block> PLASTIC_BLOCK = BLOCKS.register("Plastic", () -> new Block(BlockBehaviour.Properties.of(Material.STONE).strength(5f).color(MaterialColor.COLOR_BLUE)));
    public archemistry() {
        BLOCKS.register(FMLJavaModLoadingContext.get().getModEventBus());
    }
}

This is the class that keeps breaking it

Why don't you show the full error message?

One obvious thing is you can't have uppercase characters in block names or any ResourceLocation.

But AFAIK you don't get that error message for this.

Boilerplate:

If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com You should also read the support forum sticky post.

Nope.

It doesn't even show the StringIndexOutOfBoundException you partially quoted earlier.

Looks like your class is not in a package?

For some reason Forge doesn't like mod classes in the root package.

Boilerplate:

If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

I suggest, you download the mdk and modify that.

https://docs.minecraftforge.net/en/latest/gettingstarted/

It's almost like you are deliberately trying to make your mod have every possible misconfiguration/error.

While at the same time forcing us to continually ask for information rather than you posting the relevant files you have changed.

And you must have seen the footnote to my posts multiple times now.

Most likely this problem is caused by you not specifying your minecraft dependency or run configuration properly in the build.gradle or the mods.toml?

Or you changed something important and didn't regenerate your ide run configurations.

But I can only guess with you drip feeding information.

@FoxyWoxy do you potentially have an estimated time for fabric 1.21.5 and what will it be posted on (modrinth, etc.)

I don't know that either - newer worked with Invision Community 😕

The Forum/Guides show a customized toolbar:
https://invisioncommunity.com/4guides/themes-and-customizations/editor-and-emoticons_327/customizing-editor-toolbars-r132/
But I have no idea if this applies to v5

Regarding the Forum, "Mark all as read" seems to be hidden as default but is available if I click on my profile:
https://invisioncommunity.com/forums/topic/481218-fix-for-unreadmark-read/

I saw that it works here and also fixes the one unread thread mentioned in my first post - so I had just overlooked it

The toolbar changes are just QoL - if there is no way to change it at the moment, that's fine

I understand what you're asking for, but I don't know how to do that. The settings have moved around a bit in the admin panel and I can no longer see a way of customising the editor. If you know how to customise the editor in Invision Community 5, let me know and I'll try applying it.
