Kotlin mix with Java错误：找不到符号

我是kotlin的新手，所以我开始克隆存储库来学习这种新语言

在学习ray wenderlich教程之前，我已经安装了kotlin插件，并尝试了android项目，效果很好（我还不能发布超过2个链接）

因此，在我克隆kotlin koans并尝试在第一次运行它之后，我得到的是：

我已经尝试在互联网上搜索了。但我似乎还没有找到解决办法

我是格雷德尔

 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'
}

当我使用终端运行测试时，这就是发生的事情

    D:\kotlin-koans>gradlew test

（注：我使用android studio 2.3.3来实现）

可能与我已经使用的oracle sdk重复。因此，在阅读了这篇文章后，我尝试重新安装它。但一切都没有改变。无论如何，谢谢。试着改用IntelliJ IDEA社区版
