Failed to resolve: junit:junit:4.12

问题

I just installed Android Studios on my work computer and I created a new blank project. However, I receive the following error.

Failed to resolve: junit:junit:4.12

I have attempted numerous solutions from the previous time this question was asked but none of them seem to be working. I tried commenting out the entire line compile files('libs/junit-4.12.jar'). I tried copy pasting the jar file from the Android studio lib folder to my project lib folder and adding it as a library. On top of that,the gradle always takes more than 10 minutes to build. So any solution I want to try takes me a while. Please help.

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'
        }
    }
}

    compile 'com.android.support:appcompat-v7:24.2.1'
    testCompile 'junit:junit:4.12'
    compile files('libs/junit-4.12.jar')
}

build.bradle(Project)

// 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 {

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

JUnit is a unit testing framework for Java programming language.

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

At first modify your build.gradle from Project Level

  // 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
}

At first remove compile files('libs/junit-4.12.jar') from build.gradle ( Module Level) section .

Then Clean-Rebuild-Gradle-Run .

回答2:

Try adding mavenCentral() as a repository, and also remove compile files('libs/junit-4.12.jar')

buildscript {
    ...
    repositories {
        mavenCentral()
    }
    ...
}
