如何修复“任务'：app：processDebugResources'执行失败”。> Android资源链接失败” [Android / Flutter]

Question

它发生在任何地方。有一天，我运行的代码运行得很好，第二天，却没有碰到我的build.gradle文件或任何其他构建文件，却弹出了此错误。

我尝试了许多不同的解决方案，例如更改buildToolsVersion或将AAPT（不记得哪个）的特定标志设置为false。没事。我的app \
build.gradle文件：

 android {
 compileSdkVersion 27
 buildToolsVersion '27.0.3'

 sourceSets {
     main.java.srcDirs += 'src/main/kotlin'
 }

 lintOptions {
     disable 'InvalidPackage'
 }

 defaultConfig {
     // TODO: Specify your own unique Application ID 
     (https://developer.android.com/studio/build/application-id.html).
     applicationId "com.skydevs.bookx"
     minSdkVersion 16
     targetSdkVersion 27
     versionCode flutterVersionCode.toInteger()
     versionName flutterVersionName
     testInstrumentationRunner 
     "android.support.test.runner.AndroidJUnitRunner"
 }

 buildTypes {
     release {
         // TODO: Add your own signing config for the release build.
         // Signing with the debug keys for now, so `flutter run --release` 
         works.
         signingConfig signingConfigs.debug
     }
 }
 }

 flutter {
     source '../..'
 }

 dependencies {
   implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
   testImplementation 'junit:junit:4.12'
   androidTestImplementation 'com.android.support.test:runner:1.0.2'
   androidTestImplementation 'com.android.support.test.espresso:espresso- 
   core:3.0.2'
   implementation 'com.google.firebase:firebase-core:16.0.1'
 }

 apply plugin: 'com.google.gms.google-services'

我得到的错误是：

Answer 1

今天，我在项目中遇到了与昨天工作时相同的错误，没有任何问题。

某些升级导致此错误IMO，我的解决方案是：

• 通过Android Studio打开项目

• 打开android/build.gradle并android/app/build.gradle

• 只需纠正IDE警告的内容，它通常会警告您的SDK，Kotlin和Gradle版本等。

它不是强制性的，但您可以检查.bashrc导出或环境变量，有时它可以解决一些问题。

编辑：更新SDK版本时，请不要忘记也升级项目依赖项。
