【问题描述】：

我尝试为 com.squareup.retrofit2 模块构建.gradle 失败

    implementation "com.squareup.retrofit2:convertor-gson:${retrofitVersion}"
    implementation "com.squareup.retrofit2:adapter-rxjava2:$retrofitVersion"

带有错误信息：

Failed to resolve: com.squareup.retrofit2:convertor-gson:2.7.1

我的项目级 build.gradle 文件是：

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        google()
        maven { url "https://jitpack.io" }
        jcenter()
        }


    dependencies {
        classpath "com.android.tools.build:gradle:4.1.2"

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

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

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

应用级 build.gradle 文件为：


  compileSdkVersion 29
    buildToolsVersion "30.0.3"

    defaultConfig {
        applicationId "com.example.hedylamarr"
        minSdkVersion 15
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

【问题讨论】：

试试 2.9.0 implementation 'com.squareup.retrofit2:converter-gson:2.9.0'
我试过了，还有几个..同样的错误..

标签： android android-studio build.gradle retrofit2

【解决方案1】：

以下内容适合我：

dependencies {
    ///////
    implementation 'com.squareup.retrofit2:converter-gson:2.9.0'
    implementation("com.squareup.retrofit2:retrofit:2.9.0")
    implementation("com.squareup.okhttp3:okhttp:4.9.0") {
        force = true
    }

build.gradle

buildscript {
    ext.kotlin_version = '1.4.10'
    repositories {
        jcenter()
        mavenCentral()
        google()
        maven { url "https://jitpack.io" }
        maven { url "http://dl.bintray.com/vsmaks/maven" }
        maven { url "http://dl.bintray.com/dasar/maven" }
        maven() { url "https://oss.sonatype.org/content/repositories/snapshots" }
        maven {
            url "http://dl.bintray.com/piasy/maven"
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.0.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
        jcenter()
        mavenCentral()
        google()
        maven { url "https://jitpack.io" }
        maven { url "http://dl.bintray.com/vsmaks/maven" }
        maven { url "http://dl.bintray.com/dasar/maven" }
        maven() { url "https://oss.sonatype.org/content/repositories/snapshots" }
