Error: duplicate fabric loader for cloth-config v6.1.48 #251

minecraft_version=1.19

#Fabric api
fabric_version=0.58.0+1.19

(Also occurs in 1.19.2)

If you specify the dependencies as per the wiki, the following error will occur when running Minecraft Client in IntelliJ IDEA.

This doesn't seem to happen if I set the dependencies as below:

    modApi("me.shedaniel.cloth:cloth-config-fabric:${project.cloth_config_version}") {
        exclude(group: "net.fabricmc.fabric-api")
        exclude(group: "net.fabricmc", module: "fabric-loader")
    }

Or change modApi to modImplementation.

This did not happen with 1.18.1 + cloth-config v6.1.48 and 1.19.4 + 10.1.117.

Not really a bug, more of how Gradle resolves dependencies.

If you see an error like trying to load net.fabricmc.loader.impl.FabricLoaderImpl from target class loader, it means you have two copies of Fabric Loader on your runtime classpath. Try adding { exclude group: 'net.fabricmc', module: 'fabric-loader' } after the affecting dependencies
