android - 无法解决改造的依赖关系2

问题描述

我尝试将改造库导入到我的 gradle 文件中，但不幸的是，我遇到了太多错误。

Unable to resolve dependency for ':app@debug/compileClasspath': Could not resolve com.squareup.retrofit2:retrofit:2.4.0.
Unable to resolve dependency for ':app@debugAndroidTest/compileClasspath': Could not resolve com.squareup.retrofit2:retrofit:2.4.0.
Unable to resolve dependency for ':app@debugUnitTest/compileClasspath': Could not resolve com.squareup.retrofit2:retrofit:2.4.0.
Unable to resolve dependency for ':app@release/compileClasspath': Could not resolve com.squareup.retrofit2:retrofit:2.4.0.
Unable to resolve dependency for ':app@releaseUnitTest/compileClasspath': Could not resolve com.squareup.retrofit2:retrofit:2.4.0.

编辑 这是我的应用程序 build.gradle

apply plugin: 'com.android.application'

android {
compileSdkVersion 27
defaultConfig {
    applicationId "com.example.practice"
    minSdkVersion 19
    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'
    }
}
compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}
}

}

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

这是我的项目 build.gradle

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 {
      google()
      jcenter()
  }
}

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

我添加了最新版本的 retrofit2，但仍然出现这些错误。我已经寻找可能的解决方案，但我找不到任何东西。有人可以帮我解决这个问题吗？

解决方案

你可以添加这个插件是你的应用程序 build.gradle 文件

implementation 'com.squareup.retrofit2:retrofit:2.4.0'
implementation 'com.google.code.gson:gson:2.8.2'
implementation 'com.squareup.retrofit2:converter-gson:2.4.0'
implementation 'com.squareup.okhttp3:logging-interceptor:3.4.1'
implementation 'com.squareup.okhttp3:okhttp:3.10.0'

你可以在所有项目中像下面的代码一样更改项目 build.gradle 文件吗

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