Error:Failed to resolve: common in android studio

Question

我重新安装了 android 工作室，再次打开我的旧项目时显示以下错误：

Error:Failed to resolve: firebase-messaging
<a href="openFile:D:/Android projects/Porject_name/app/build.gradle">Open File</a>

Error:Failed to resolve: common
<a href="openFile:D:/Android projects/Porject_name/app/build.gradle">Open File</a>

build.gradle（项目）文件：

// Top-level build file where you can add configuration options common to 

all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.3'
        classpath 'com.google.gms:google-services:3.1.0'

    }
}

allprojects {
    repositories {
        jcenter()
        mavenCentral()

        google()


        maven {
            url "https://jitpack.io"
        }

    }
}

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

build.gradle（应用程序）文件：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion '27.0.3'
    useLibrary 'org.apache.http.legacy'

    defaultConfig {
        applicationId "com.example.abc"
        minSdkVersion 16
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:26.1.0'
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:design:26.1.0'
    compile 'com.android.support:support-v4:26.1.0'
    compile 'com.github.traex.rippleeffect:library:1.3'
    compile 'com.mcxiaoke.volley:library-aar:1.0.0'
    compile 'com.google.firebase:firebase-messaging:12.0.0'
    compile 'com.baoyz.swipemenulistview:library:1.3.0'

    compile 'com.applandeo:material-calendar-view:1.4.0'
    compile 'com.github.michaelye.easydialog:easydialog:1.4'
    implementation 'de.hdodenhof:circleimageview:2.2.0'
    compile 'com.squareup.picasso:picasso:2.5.2'

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

我已经添加了所有必需的插件和 sdk，但仍然无法正常工作。安装的 Firebase plugins.even google 也可以播放服务。在我卸载工作室之前它工作正常。请帮忙。

Answer 1

Add/Move 这个 maven {url "https://maven.google.com"} 到顶部使我的工作在 build.gradle

Answer 2

这对我有用。我只是像这样重新排序

repositories {
    mavenCentral()
    mavenLocal()
    google()
    jcenter()
  }

Answer 3

当我在 Android Studio preview(Android Studio 3.2 Canary 18) 版本中有运行项目时，我也遇到了这个问题这改变了

gradle-wrapper.properties分配url到distributionUrl=https\://services.gradle.org/distributions/gradle-4.6-all.zip
并且它还影响了 build.gradle（项目级别）中的类路径 classpath 'com.android.tools.build:gradle:3.2.0-alpha16'

因此 android studio 预览版所做的上述更改导致我的项目出现 Error:Failed to resolve: common <a href..> 错误，所以我通过将它们改回稳定

简单地解决了这个问题

解决方案

在gradle-wrapper.properties中将url更改为distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip

将类路径更改为 classpath 'com.android.tools.build:gradle:3.1.2'

Error:Failed to resolve: common in android studio
