ANDROID:org.gradle.api.GradleException:找不到满足版本约束的“org.jetbrains.kotlin:kotlin stdlib”版本

我试着运行一个测试类，发现了下面这个构建错误。它仅在尝试运行测试时显示，而在构建和运行应用程序时不显示。对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

一些库将需要特定版本的Kotlin，通常情况下，如果它们依赖于更新的语言功能，例如Kotlin 1.3中的协同程序

在您的案例中，androidx.room:room测试：2.1.0-alpha04通过其androidx.room:room迁移：2.1.0-alpha04依赖项需要Kotlin 1.3.0或更高版本，但您的项目设置为Kotlin 1.2.71

典型的简单解决方案是升级Kotlin版本。在一个典型的当前Android Studio项目中，它设置在顶级build.gradle文件的buildscript闭包中的ext.kotlin_版本行中。否则，请查找Gradle构建脚本和属性文件，查找1.2.71。替换为1.3.0或更高版本-自2019年4月底起，Kotlin的最新生产版本为1.3.30

---

如果升级Kotlin版本会导致其他问题，例如测试失败，则可以选择降级要求更高Kotlin版本的依赖项。但是，最终，您将需要解决问题并使用当前的Kotlin版本。

一些库将需要Kotlin的特定版本，通常情况下，如果它们依赖于更新的语言功能，例如Kotlin 1.3中的协程

在您的案例中，androidx.room:room测试：2.1.0-alpha04通过其androidx.room:room迁移：2.1.0-alpha04依赖项需要Kotlin 1.3.0或更高版本，但您的项目设置为Kotlin 1.2.71

典型的简单解决方案是升级Kotlin版本。在一个典型的当前Android Studio项目中，它设置在顶级build.gradle文件的buildscript闭包中的ext.kotlin_版本行中。否则，请查找Gradle构建脚本和属性文件，查找1.2.71。替换为1.3.0或更高版本-自2019年4月底起，Kotlin的最新生产版本为1.3.30
