Cannot configure krotoPlus protoc task via Kotlin gradle script, fallsback to asciipb file

[Strum355]

Kroto Plus version: 0.6.1
com.google.protobuf version: 0.8.15

When trying to adapt the example krotoPlusConfig.gradle to Kotlin Gradle script, I havent been successful. My only success has been with the config defined in a json file (and presumably will also work for asciipb etc).

For the first code snippet, I get the following exception:

Execution failed for task ':semanticdb-kotlin:generateProto'.

    generatedFilesBaseDir = sourceSets.main.get().kotlin.sourceDirectories.asPath.split(":")[0].removeSuffix("main/kotlin")

    plugins {

    }

    generateProtoTasks {
        val krotoConfig = file("${projectDir}/krotoconfig.json")
        all().forEach { task ->
            task.inputs.files(krotoConfig)

            task.plugins {
                id("kroto") {
                    outputSubDir = "java"
                    option(krotoPlus.config["main"].asOption())
					//option("ConfigPath=${krotoConfig}")
                }
            }
        }
    }
}

With the following diff, I get com.github.marcoferrer.krotoplus.config.CompilerConfig$Builder cannot be cast to com.github.marcoferrer.krotoplus.gradle.compiler.CompilerConfigWrapper:
