java - 运行 react-native run-android 时出现 React Native compileDebugJavaWithJavac 错误

Question

当我尝试启动我的 react native 项目时，需要帮助来解决这个 compileDebugJavaWithJavac 问题。我再次尝试使用 ./gradlew build in project/android 文件夹。发生了同样的错误。请帮忙！

我使用 react-native doctor 命令运行项目，我已经收到了这些，但错误仍然发生。

Common
 ✓ Node.js
 ✓ yarn
 ✓ npm

Android
 ✓ JDK
 ✓ Android Studio - Required for building and installing your app on Android
 ✓ Android SDK - Required for building and installing your app on Android
 ✓ ANDROID_HOME

错误
