Question

当您尝试运行命令时：

react-native run-android

发生以下错误：

> Task :react-native-gesture-handler:compileDebugJavaWithJavac
Note: C:\Users\jefer\Desktop\react\new\node_modules\react-native-gesture-handler\android\src\main\java\com\swmansion\gesturehandler\react\RNGestureHandlerButtonViewManager.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.

> Task :app:processDebugResources FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:processDebugResources'.
> Package 'com.new' from AndroidManifest.xml is not a valid Java package name as 'new' is a Java keyword.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

error Command failed: gradlew.bat app:installDebug

我尝试使用：

cd android && gradlew clean

但是它并不能解决问题...我还删除了android和iOS文件夹，并使用了以下命令：

react-native eject
react-native link

但是没有用。

您的应用程序包名称存在问题

您在AndroifManifest.xml中将应用程序包名称设置为 com.new 无效。更改应用程序包名称，因为新是Java中的保留关键字

任务流程的执行失败
