引用 Kotlin 时出现 ClassNotFoundException 类
ClassNotFoundException when referencing Kotlin classes
我尝试开始将基于 Java 的多索引项目迁移到 Kotlin，但每当应用程序尝试引用 Kotlin class 时，我都会收到 ClassNotFoundException。奇怪的是，相同的代码有时有效有时无效。有些计算机可以生成可用的 apk，而有些则不能。有时重建足以解决问题。
我已经尝试 google 它，但我只找到 this 线程，但没有解决方案。这个东西对其他人是否正常工作，或者还没有任何 multidexed Kotlin 项目吗？
我试过 AS 2.3.3 和 AS 3.0.0-beta6、2.3.3 android 插件，kotoin 版本 1.1.50，没有混淆器 .

如果您使用的是 Java 8，那么您也应该使用 Kotlin jre8。
compile "org.jetbrains.kotlin:kotlin-stdlib-jre8:$kotlin_version"
终于解决了这个问题！该异常是由 RetroLambda 错误引起的，幸好在我更新到 3.7.0 后消失了。构建是不确定的，因为 gradle clean 似乎并没有删除所有内容。在我手动删除 app 和 root 模块中的 build 文件夹后，结果变得确定。
