Question

更新：
我在Github中放了一个演示：TestBuildSrc，在buildSrc文件夹下只有一个Kotlin文件和一个Java文件。发生相同的错误（Test是一个Java类）：

 Unresolved reference: Test

旧问题：
我需要一个R2文件，所以我将JakeWharton的butterknife-gradle-plugin复制到我的buildSrc目录中。

奇怪的是，当我在Kotlin文件中调用Java类时，发生了一些错误：

> Task :buildSrc:compileKotlin FAILED
w: Runtime JAR files in the classpath have the version 1.1, which is older than the API version 1.3. Consider using the runtime of version 1.3, or pass '-api-version 1.1' explicitly to restrict the available APIs to the runtime of version 1.1. You can also pass '-language-version 1.1' instead, which will restrict not only the APIs to the specified version, but also the language features

FAILURE: Build failed with an exception.

Test或FinalRClassBuilder是Java类。我的gradle文件在buildSrc文件夹下（修改源集块不起作用）：

apply plugin: 'kotlin'
apply plugin: "groovy"
...

sourceSets {
    main {
//        groovy {
//            srcDir 'src/main/java'
//        }

        kotlin {
//            srcDir 'src/main/java'
            srcDir 'src/main/kotlin'
        }

        java {
            srcDir 'src/main/java'
        }

        resources {
            srcDir 'src/main/resources'
        }
    }
}

sourceCompatibility = "1.8"
targetCompatibility = "1.8"

这里发生了什么？

buildSrc中的Kotlin文件不能使用Java类吗？
