Flutterandroid構建失敗，并顯示“任務':app:processReleaseResources'執行失敗”。更改gradle構建工具版本后

我正在為 android 構建一個 flutter 應用程式。

我從...更新了gradle構建工具版本

classpath 'com.android.tools.build:gradle:3.5.0'

到

classpath 'com.android.tools.build:gradle:4.1.3'

現在我收到構建錯誤...

Execution failed for task ':app:processReleaseResources'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade
   > Android resource linking failed
     /home/user/src/myapp/build/app/intermediates/packaged_manifests/release/AndroidManifest.xml:34: AAPT: error: attribute android:usesPermissionFlags not found.

我的 build.gradle 如下...

buildscript {
    ext.kotlin_version = '1.3.50'
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.3'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.3.5'

    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

我的應用程式/build.gradle

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')

    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

uj5u.com熱心網友回復：

檢查 android/app 中的 build.gradle

compileSdkVersion 30 minSdkVersion 16 targetSdkVersion 30

如果這沒有解決，那么您可能在 android/app/src/main/AndroidManifest.xml 中的 android manifest 中缺少權限

uj5u.com熱心網友回復：

錯誤資訊一般來自 AAPT2。
可以看到，這個屬性從 API 級別 17 開始就存在了。

出于除錯目的，合并的AndroidManifest.xml@line 34 會更有趣，因為android:usesPermissionFlags即使來自哪里的問題仍然存在，因為insideAndroidManifest.xml模塊:app沒有這條線并且合并版本需要從某個地方獲取它 - 這只能是另一個模塊或某個AAR庫。

buildToolsVersion "30.0.3"應該可以作業，但由于沒有其他任何宣告，這仍然應該是類似的......盡管如此，Android Studio（存檔）的版本也起作用（它需要匹配 Gradle 插件的版本，即4.1.3，與 Gradle 4.4)... 或者對于當前的“北極狐”，這將是7.0.3，使用 Gradle 7.2（您正在構建一個遺留專案）。

aapt2 version 應該回傳：

Android 資產打包工具 (aapt) 2.19-6966805

這將是包含要使用的版本的表格。
實際上，Gradle 太新的可能性也很小。

順便說一句......我什至可以證明這是一個假設（除了:clean任務通常駐留在根build.gradle而不是模塊中build.gradle，這是一個潛在的問題）：

task clean(type: Delete) {
    delete rootProject.buildDir
}

這表明，./build正在被洗掉，但不是./app/build。我什至會走得更遠，不僅 delete ./build，而且~/.gradle/cache. 如果應該有更多的 Java/Kotlin 模塊存在，請確保其中沒有一個是使用過時的buildToolsVersion.

將其保留在 module 中時build.gradle，應將其全部洗掉：

task clean(type: Delete) {
    delete rootProject.buildDir
    delete project.buildDir
}
