Why am I getting this warning when the library is built with 1.7.10 and I'm also using 1.7.10?
y
The library might be using context receivers
m
It's enabled both in the library and my own build.gradle.kts
It looks like that one gets ignored while compiling, but I'm getting errors for extending an interface with context receivers. It worked fine in the library itself, but not for using it in a different project it seems
Copy code
// library
fun interface Command {
    context(GunpowderModule, CommandBuilderContext)
    fun build()
}

// elsewhere:
object HelpCommand : Command {
    context(GunpowderModule, CommandBuilderContext)
    override fun build() {
        // ...
    }
}
Copy code
// my code
object BalanceCommand : Command {
    context(GunpowderModule, CommandBuilderContext)
    override fun build() {
    }
}
Copy code
