我刚刚在我的Android项目中启用了Kotlin,我偶然发现了一个警告.在第二次构建(Build - > Rebuild Project)之后,此警告显示在Messages下:

Warning:Runtime JAR files in the classpath should have the same version. These files were found in the classpath:
~/.gradle/caches/modules-2/files-2.1/org.jetbrains.kotlin/kotlin-stdlib-jdk8/1.2.10/85fe1811f3e586d0cc53aba1394d8089f1862215/kotlin-stdlib-jdk8-1.2.10.jar (version 1.2)

看起来第二个版本包含过时kotlin-stdlib-jre7-1.1.51.jar的缓存.在干净的构建(构建 - >清理项目)之后,警告消失,下一个重建项目再次启动它.

我正在使用Android Studio 3.0.1并且我明确地将Kotlin依赖项包含在版本中:

的build.gradle

buildscript {
    ext {
        // shared build properties
        kotlin_version      = '1.2.10'
        buildToolsVersion   = '27.0.2'
        minSdkVersion       = 15
        targetSdkVersion    = 27
        compileSdkVersion   = 27
    }
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath …
