Kotlin смешивается с ошибкой Java: не удается найти символ

Я новичок в kotlin, поэтому начинаю клонировать https://github.com/Kotlin/kotlin-koans репозиторий, чтобы узнать этот новый язык.

Я уже устанавливаю плагин kotlin, а также пытаюсь выполнить проект андроида перед тем, как следовать руководству ray-wenderlich, и он отлично работает (я не могу разместить более двух ссылок.)

Поэтому, после того, как я клонировал котлин-коан и попытаюсь запустить его в первый раз, это то, что я получил: Скриншот

Я пытаюсь искать в Интернете уже. Но похоже, что я все еще не могу найти решение.

Это gradle.build

buildscript { ext.kotlin_version = '1.1.0' repositories { mavenCentral() } dependencies { classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" } } apply plugin: 'kotlin' sourceSets { main.java.srcDirs += 'src' test.java.srcDirs += 'test' } repositories { mavenCentral() } dependencies { compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version" compile 'com.google.guava:guava:16.0' testCompile 'junit:junit:4.12' } 

И когда я запускаю тест с помощью терминала, это то, что происходит.
