Question

我开发了一个Android应用程序，过了几天，我在logcat和不同步项目中看到以下错误！

在错误下方显示我：

app/build.gradle    
Failed to resolve: design   
Failed to resolve: appcompat-v7 
Failed to resolve: cardview-v7

我的build.gradle文件：

        classpath 'com.google.gms:google-services:4.1.0'


        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        mavenCentral()
        google()
        maven { url "https://jitpack.io" }
        maven { url 'https://maven.google.com'}
    }
}

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

我确定我的互联网已连接。

我该如何解决？

Answer 1

更改顺序并将google()放在jcenter()的{{1}}之前

为什么？ here

您的最终项目级别build.gradle应该看起来像这样

build.gradle

Answer 2

尝试将此存储库添加到allprojects项目的build.gradle和jcenter() mavenCentral() google()中

int

我希望这会对您有所帮助。
