Update readme to show how to configure using new gradle plugin syntax

[dalewking]

The readme shows the old way to configure the plugin using classpath inside buildscript, but since you are publishing in the gradle plugin portal there is no reason to so it that way. The readme should reflect the prefered way using the new plugin syntax.

I've figured it out how to make it work in gradle kotlin dsl:

You can apply the plugin with:

plugins {
    kotlin("multiplatform")
    id("com.codingfeline.buildkonfig")
}

I added these imports to the file:

import com.codingfeline.buildkonfig.compiler.FieldSpec.Type
import com.codingfeline.buildkonfig.gradle.BuildKonfigExtension
import com.codingfeline.buildkonfig.gradle.TargetConfigDsl

And here is what I did to configure:

configure<BuildKonfigExtension> {
    packageName = "com.genesys.purecloud.wfmshared"

    defaultConfigs {
        buildConfigField(Type.STRING, "OAUTH_CLIENT_ID", "")
        buildConfigField(Type.STRING, "OAUTH_CLIENT_SECRET", "")
        buildConfigField(Type.STRING, "DEFAULT_ENVIRONMENT",
            if(publicReleaseBuild) "PRODUCTION" else "DEVELOPMENT")
        buildConfigField(Type.BOOLEAN, "ALLOW_ENVIRONMENT_SELECTION",
            (!publicReleaseBuild).toString())
    }

    targetConfigs("android", closureOf<TargetConfigDsl> {
        buildConfigField(Type.STRING, "OAUTH_CLIENT_ID",
            project.properties["oauth_client_id_android"].toString())
        buildConfigField(Type.STRING, "OAUTH_CLIENT_SECRET",
            project.properties["oauth_client_secret_android"].toString())
    })
    targetConfigs("ios", closureOf<TargetConfigDsl> {
        buildConfigField(Type.STRING, "OAUTH_CLIENT_ID",
            project.properties["oauth_client_id_ios"].toString())
        buildConfigField(Type.STRING, "OAUTH_CLIENT_SECRET",
            project.properties["oauth_client_secret_ios"].toString())
    })
}

This is hampered by the fact that for target configs you are using Closure, which is Groovy specific and requires the configureOf wrapper. As noted here you should use Action, not Closure. You did that on defaultConfig but not on targetConfigs.

And I guess I should have tested that before posting as that fails with:
org.gradle.api.internal.FactoryNamedDomainObjectContainer_Decorated cannot be cast to com.codingfeline.buildkonfig.gradle.TargetConfigDsl

[dalewking]

OK, this works, but once again would be simplified by you switching to Action from Closure:

targetConfigs(closureOf<NamedDomainObjectContainer<TargetConfigDsl>> {
    create("android") {
        buildConfigField(
            Type.STRING, "OAUTH_CLIENT_ID",
            project.properties["oauth_client_id_android"].toString()
        )
        buildConfigField(
            Type.STRING, "OAUTH_CLIENT_SECRET",
            project.properties["oauth_client_secret_android"].toString()
        )
    }
    create("ios") {
        buildConfigField(
            Type.STRING, "OAUTH_CLIENT_ID",
            project.properties["oauth_client_id_ios"].toString()
        )
        buildConfigField(
            Type.STRING, "OAUTH_CLIENT_SECRET",
            project.properties["oauth_client_secret_ios"].toString()
        )
    }
})
