Solution file argument isn't being passed

[chb0github]

Maybe I am missing something, but based on everything I see, this should produce results and yet, it doesn't seem to be passing the solution file along to the CLI despite being set. It's also not picking up the nuget on the path - which isn't so crucial, but curious

import com.ullink.NuGetRestore


plugins {
    id("com.ullink.nuget") version "2.20" apply false
}

subprojects {
    apply(plugin = "com.ullink.nuget")
    val solution =projectDir.walkTopDown().find { it.extension == "sln" }!!

    tasks {

        val restore by creating(NuGetRestore::class) {
            setSolutionDirectory(solution.parentFile.path)
            setSolutionFile(solution.path)
            verbosity = "detailed"
            sources = setOf(
                "https://www.nuget.org/api/v2",
                "http://prism-prod-oct/NuGetLocalServer/nuget"
            )
            println("executable: ${executable}")
            println("Args: ${args}")
            println("task solution file: ${this.solutionFile}")
        }

    }
}
