我是kotlin的新手，所以我开始克隆https://github.com/Kotlin/kotlin-koans存储库来学习这个新的languange。
我已经安装了kotlin插件，并且在关注ray-wenderlich教程之前也尝试使用android项目并且它工作正常（我还不能发布超过2个链接。）
所以在我克隆kotlin-koans并尝试第一次运行它之后，这就是我得到的：Screenshot
我尝试在互联网上搜索。但似乎我仍然无法找到解决方案。
这是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'
}
当我使用终端运行测试时，这就是发生的事情。
D:\kotlin-koans>gradlew test
