找不到 aapt2-4.0.0-6051327-linux.jar (com.android.tools.build:aapt2:4.0.0-6051327)

Question

我在新设备上安装了 android studio，并从 android studio 模板开始了一个新项目。但是当我想运行设备上的应用程序时，构建过程失败并显示此消息：

Could not find aapt2-4.0.0-6051327-linux.jar (com.android.tools.build:aapt2:4.0.0-6051327). Searched in the following locations: https://dl.google.com/dl/android/maven2/com/android/tools/build/aapt2/4.0.0-6051327/aapt2-4.0.0-6051327-linux.jar

这是我的 android 工作室详细信息：

这是我的 gradle 个文件：

    }
}

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

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

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {

            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

    implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
    implementation 'androidx.core:core-ktx:1.3.0'

}

我看到过类似的问题，但没有一个有帮助，两个最相关的帖子是 and Could not find com.android.tools.build:aapt2:3.2.0 正如您在我提供的文件中看到的那样，无法解决我的问题，因为解决方案已经实施.

Answer 1

我的解决方案是将 android studio 降级到 3.6.1。为了完成这项工作，我也需要降级 gradle。所以我将它降级到 5.6.4。所以我的 gradle-wrapper.properties 看起来像这样：

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.4-all.zip

然后我对 gradle 插件进行了降级：

// Top-level build file where you can add configuration options common to all sub-projects/modules.
//apply plugin: 'com.android.application'
buildscript {
    ext.kotlin_version = "1.3.72"
    ext.realm_version = '6.0.2'
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.6.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath "io.realm:realm-gradle-plugin:$realm_version"
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

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

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

**注意：

请注意，这只是一种变通方法，我找不到合适的理由，因此找不到合适的解决方案！
