失敗：構建失敗並出現異常 - Flutter

Question

我試圖構建我的應用程序，但它總是返回這個奇怪的錯誤：-

Launching lib\main.dart on M2003J15SC in debug mode...

FAILURE: Build failed with an exception.

* What went wrong:
A problem was found with the configuration of task ':location:compileDebugJavaWithJavac'.
> File 'C:\Native\findhelpapp\findhelpapp\build\location\intermediates\annotation_processor_list\debug\annotationProcessors.json' specified for property 'processorListFile' does not exist.

* 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.

* Get more help at https://help.gradle.org

BUILD FAILED in 52s
Exception: Gradle task assembleDebug failed with exit code 1
Exited (sigterm)

我嘗試運行flutter clean並重建項目，但它也不起作用:"(

那么我應該怎么做才能解決這個錯誤？

我的flutter doctor記錄：-

Answer 1

1. 檢查 Android SDK 和 Jdk Location

2.復制 gradle.properties 末尾的下一行

android.useAndroidX=true

android.enableJetifier=真

3. 並設置最新版本

在文件 app\build.gradle

android {
 compileSdkVersion 28

defaultConfig {
minSdkVersion 21
targetSdkVersion 28
multiDexEnabled true

}

4. 運行你的應用程序獲得收益
