此版本中使用了已弃用的 Gradle 功能,使其与 Gradle 6 不兼容

Deprecated Gradle features were used in this build, making it incompatible with Gradle 6

我尝试在 react-native 中获取 Apk,但它没有给我任何东西。 Apk 文件中的发布文件是空的,在 Gradlew 捆绑包发布完成后,它说

    Deprecated Gradle features were used in this build, making it incompatible with Gradle 6.0.
Use '--warning-mode all' to show the individual deprecation warnings.
See https://docs.gradle.org/5.4.1/userguide/command_line_interface.html#sec:command_line_warnings

我找不到解决这个问题的方法

你试过运行./gradlew bundleRelease --warning-mode all了吗?

它将为您提供有关不兼容内容的更多信息。

这发生在我的 React Native 项目中。这是在 Windows(10 64 位)中修复它的分步操作:

1) 运行 avd 没有 Android Studio (https://windowsloop.com/launch-avd-manager-without-android-studio/)

2) 在项目 gradle wrapper 的另一个控制台 运行 中(您必须安装 Gradle 5.4.1 (https://gradle.org/install/))

3) 然后移动到cd android,这里运行gradlew clean

4) 移动到根 cd.. 和 运行 react-native start

5) 在另一个控制台中 运行 在您的项目中 react-native run-android

  1. 转到项目文件 运行 gradle wrapper.
  2. 然后转到cd android,这里运行 gradle clean.
  3. 移动到根 "cd.." 和 运行 react-native start
  4. 在另一个控制台中 运行 在您的项目中 react-native run-android

您的项目将运行宁!

2020年如果你有同样的问题,Powershell的这个建议对我有帮助。

.\emulator.exe -avd "MyAvd"

运行 在您的 SDK 模拟器所在的目录中执行以上命令 (C:\Users\AppData\Local\Android\Sdk\emulator),然后您可能会得到一些说明,如下所示:

您的模拟器已过时,请启动 Android Studio 进行更新:

  • 开始Android工作室
  • Select 菜单 "Tools > Android > SDK Manager"
  • 单击 "SDK Tools" 选项卡
  • 选中 "Android Emulator" 复选框
  • 点击"OK"

这个 link 也会有帮助。 link

要解决此问题,您需要找到此文件 (gradle-wrapper.properties) 该文件位于项目文件夹的 d 路径 (android/gradle/wrapper) 中....打开文件并更改此行

distributionUrl=https://services.gradle.org/distributions/gradle-5.5-all.zip 

对此:
