Question

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）”

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。

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 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
}

build errors after gradle sync

Answer 1

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
}

Answer 2

参考：not-able-to-import-com-squareup-okhttp-okhttpclient

Gradle应该有这样的一行

compile 'com.squareup.okhttp3:okhttp:3.0.1'

这就是您导入它的方式

import okhttp3.OkHttpClient;

因为OkHttpClient已从软件包com.squareup.okhttp移至最新版本的okhttp3。

Answer 3

更改类路径

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

到

classpath 'com.google.gms:google-services:4.2.0'
