Gradle错误-无法下载okhttp.jar文件2.7.2 [英] Gradle error - could not download okhttp.jar file 2.7.2

问题描述

当我添加firebase函数库(实现'com.google.firebase:firebase-functions:16.1.0')时，android studio(3.1.4)抛出"无法解决:app @ debug/compileClasspath"的依赖项:无法下载okhttp.jar(com.squareup.okhttp:okhttp:2.7.2)"

when i added the firebase functions library (implementation 'com.google.firebase:firebase-functions:16.1.0') , android studio(3.1.4) throws "Unable to resolve dependency for ':app@debug/compileClasspath': Could not download okhttp.jar (com.squareup.okhttp:okhttp:2.7.2)"

我尝试添加"实现文件('libs/okhttp-2.7.2.jar')"，但仍然出现相同的错误.

I tried to add "implementation files('libs/okhttp-2.7.2.jar')" but still got the same error.

这是我的build.gradle(app)

apply plugin: 'com.android.application'  

android {    
    compileSdkVersion 27  
    buildToolsVersion '27.0.3'  
    defaultConfig {  
        applicationId "com.caliber.mskhan.calibergaming"  
        minSdkVersion 16  
        targetSdkVersion 27  
        versionCode 1  
        versionName "1.0"  
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"  
    }  
    buildTypes {  
        release {  
            minifyEnabled false  
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'  
        }  
    }  
}

    implementation fileTree(include: ['*.jar'], dir: 'libs')

    //implementation files('libs/okhttp-2.7.2.jar')  
}  
apply plugin: 'com.google.gms.google-services'  

这是我的build.gradle(project)

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.4'

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

        classpath 'com.google.gms:google-services:4.0.1'
    }
}

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

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

gradle同步后生成错误

推荐答案

Change this 


// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.4'


        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'com.google.gms:google-services:4.0.1'
        classpath 'com.google.firebase:firebase-plugins:1.0.4'
    }
}

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

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