android - 无法解析 : junit:junit:4. 12

Question

我刚刚在我的工作计算机上安装了 Android Studios，并创建了一个新的空白项目。但是，我收到以下错误。

解析失败:junit:junit:4.12

从上次被问到这个问题开始，我尝试了很多解决方案，但似乎没有一个有效。我尝试注释掉整行 compile files('libs/junit-4.12.jar')。我尝试将 jar 文件从 Android Studio lib 文件夹复制粘贴到我的项目 lib 文件夹并将其添加为库。最重要的是，gradle 总是需要超过 10 分钟的时间来构建。所以我想尝试的任何解决方案都需要我一段时间。请帮忙。

apply plugin: 'com.android.application'

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.3"
    defaultConfig {
        applicationId "com.example.mabbasi.myapplication"
        minSdkVersion 15
        targetSdkVersion 24
        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-v7:24.2.1'
    testCompile 'junit:junit:4.12'
    compile files('libs/junit-4.12.jar')
}

build.bradle(项目)

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

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.1'

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

allprojects {
    repositories {
        jcenter()
    }
}

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

JUnit 是 Java 编程语言的单元测试框架。

JUnit has been important in the development of test-driven development .

首先从项目级别修改你的build.gradle

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

buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }
    dependencies {

        classpath 'com.android.tools.build:gradle:2.2.1'


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

allprojects {
    repositories {
        jcenter()
        mavenCentral()
    }
}

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

重复

首先从 build.gradle ( Module Level) 部分删除 compile files('libs/junit-4.12.jar') 。

然后Clean-Rebuild-Gradle-Run。
