尝试通过IntelliJ 运行示例CorDapp(https://github.com/corda/cordapp-example)时,收到以下错误:

无法将使用JVM目标1.8构建的字节码内联到使用JVM目标1.6构建的字节码中

如何修改IntelliJ设置,以便所有字节码都使用相同的JVM目标构建？

我使用 Google Maps SDK (v2) 的应用程序刚刚开始崩溃，出现以下异常：

在 v3 beta SDK 中，堆栈跟踪是：

在 DialogFragment() 中使用 Android 视图绑定的正确方法是什么？

官方文档只提到了 Activity 和 Fragment：https : //developer.android.com/topic/libraries/view-binding

我目前正在使用 kotlin 开发一个多平台模块。为此，我依赖expect/actual机制。

我声明了一个简单的类Common.kt：

expect class Bar constructor(
    name: String
)

我想在通用方法中使用定义的类（也存在于 中Common.kt）：

fun hello(bar: Bar) {
    print("Hello, my name is ${bar.name}")
}

实际实现定义在Jvm.kt：

actual data class Bar actual constructor(
    val name: String    
)

问题是我的hello函数中出现以下错误

未解决的参考：名称

我究竟做错了什么？

我尝试运行一个测试类，并发现了下面的构建错误。它仅在尝试运行测试时出现，而不是在构建和运行应用程序时出现。关于如何解决这个问题有什么建议吗？我根本没有在我的应用程序中使用 kotlin。
