I'm just starting to play around and have this little test:

class Test (
    val id: UUID
) {
	private constructor(builder: Builder) : this(builder.id)
	companion object {
		inline fun build(id: UUID, block: Builder.() -> Unit)  = Builder(id). apply(block).build()
	}
	class Builder(
		val id: UUID) {
        var text: String? = null
        fun build() = Test(this)
    }
}

but, at apply, i'm getting Unresolved reference: apply. I am using the Eclipse Kotlin plugin. I know, I should be using IDEA....... one step at a time. 🙂

kotlin-stdlib is listed as a dependency?

[kango_v]

I'll try and find it. Do you have to put this in pom.xml or build.gradle?

[kango_v]

You are a star. added it to the build.gradle file as compileOnly and it works 🙂 But, do you need this at run time as well?

[Andreas Sinz]

Yes, the stdlib needs to be in the classpath at runtime

[kango_v]

Got it 👍

Although if you're only going to be using apply you might be fine without it, since it's inline.
