Kotlin: Unresolved reference:get

I’m trying to import khttp to my Kotlin project on IntelliJ. I have used Grandle. My build.grandle is

buildscript {

    repositories {
        mavenCentral()
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.0.1"

    }
} 
apply plugin: 'java'
apply plugin: 'kotlin'

sourceCompatibility = 1.5

repositories {
    mavenCentral()
    maven { url "https://jitpack.io" }
}

dependencies {
    compile "org.jetbrains.kotlin:kotlin-stdlib:1.0.1"
    testCompile group: 'junit', name: 'junit', version: '4.11'
    compile "com.github.jkcclemens:khttp:d4c7950154"
}

What can I do ?

A short note ahead: Kotlin requires at least Java 6. You might want to correct your sourceCompatibility.

Here’s the output that I get when I run your build.gradle:

22:01 $ ./gradlew build

Please post the full error message because it can’t be reproduced with what you show us in your initial posting. May I kindly ask that you also improve the formatting to improve readability. Thank you!

Finally I’m using Fuel library https://github.com/kittinunf/Fuel instead of Khttp and it works… I think it wasn’t build.grandle fault. Maybe Khttp is not updated.
