Holy hell that fixed it, I replaced the "-" with a "_" and everything is working. Now I know, thank you very much!

I will try that when I get a chance, I did use a "-" but I thought that was allowed. Will update the post when I try that. Thanks!

I have been using Java for a while now, but admittedly have been more into Python in recent years. Anyway, I am following a tutorial on Youtube to setup the IntelliJ IDE for making a Forge mod (the channel is "Modding by Kaupenjoe"). I have done everything in the first video to the letter, and yet when I run the "runClient" task via Gradle to see if I can boot up Minecraft with my tutorial mod (nothing new in the mod, just blank template basically), I receive the following error: Exception in thread "main" java.lang.IllegalStateException: Failed to find system mod: minecraft at MC-BOOTSTRAP/[email protected]/net.minecraftforge.fml.loading.ModSorter.detectSystemMods(ModSorter.java:181) at MC-BOOTSTRAP/[email protected]/net.minecraftforge.fml.loading.ModSorter.buildUniqueList(ModSorter.java:145) at MC-BOOTSTRAP/[email protected]/net.minecraftforge.fml.loading.ModSorter.sort(ModSorter.java:53) at MC-BOOTSTRAP/[email protected]/net.minecraftforge.fml.loading.moddiscovery.ModValidator.stage2Validation(ModValidator.java:98) at MC-BOOTSTRAP/[email protected]/net.minecraftforge.fml.loading.FMLLoader.completeScan(FMLLoader.java:172) at MC-BOOTSTRAP/[email protected]/net.minecraftforge.fml.loading.FMLServiceProvider.completeScan(FMLServiceProvider.java:91) at MC-BOOTSTRAP/[email protected]/cpw.mods.modlauncher.TransformationServiceDecorator.onCompleteScan(TransformationServiceDecorator.java:174) at MC-BOOTSTRAP/[email protected]/cpw.mods.modlauncher.TransformationServicesHandler.lambda$triggerScanCompletion$24(TransformationServicesHandler.java:145) at java.base/java.util.stream.ReferencePipeline$3$1.accept(ReferencePipeline.java:197) at java.base/java.util.HashMap$ValueSpliterator.forEachRemaining(HashMap.java:1779) at java.base/java.util.stream.AbstractPipeline.copyInto(AbstractPipeline.java:509) at java.base/java.util.stream.AbstractPipeline.wrapAndCopyInto(AbstractPipeline.java:499) at java.base/java.util.stream.AbstractPipeline.evaluate(AbstractPipeline.java:575) at java.base/java.util.stream.AbstractPipeline.evaluateToArrayNode(AbstractPipeline.java:260) at java.base/java.util.stream.ReferencePipeline.toArray(ReferencePipeline.java:616) at java.base/java.util.stream.ReferencePipeline.toArray(ReferencePipeline.java:622) at java.base/java.util.stream.ReferencePipeline.toList(ReferencePipeline.java:627) at MC-BOOTSTRAP/[email protected]/cpw.mods.modlauncher.TransformationServicesHandler.triggerScanCompletion(TransformationServicesHandler.java:147) at MC-BOOTSTRAP/[email protected]/cpw.mods.modlauncher.Launcher.run(Launcher.java:95) at MC-BOOTSTRAP/[email protected]/cpw.mods.modlauncher.Launcher.main(Launcher.java:78) at MC-BOOTSTRAP/[email protected]/cpw.mods.modlauncher.BootstrapLaunchConsumer.accept(BootstrapLaunchConsumer.java:26) at MC-BOOTSTRAP/[email protected]/cpw.mods.modlauncher.BootstrapLaunchConsumer.accept(BootstrapLaunchConsumer.java:23) at [email protected]/cpw.mods.bootstraplauncher.BootstrapLauncher.main(BootstrapLauncher.java:141) > Task :runClient FAILED Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

Which doesn't make sense since, again, I followed the tutorial to the letter. But my experience modding in the Forge ecosystem is very limited. Any help or suggestions would be appreciated. I thought it was because I didn't have a forge client installed for this version in my minecraft launcher so I installed that, reloaded Gradle in IntelliJ but same error.
