Mod loading fails with java.lang.StringIndexOutOfBoundsException

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.

    Boilerplate:

    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

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

    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.
