无法解决:junit:junit:4.12 [英] Failed to resolve: junit:junit:4.12

问题描述

我刚刚在工作计算机上安装了Android Studio，并创建了一个新的空白项目.但是，我收到以下错误.

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

无法解决:junit:junit:4.12

从上次提出这个问题开始，我就尝试了许多解决方案，但是似乎都没有用.我尝试注释掉整行编译文件('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，构建gradle总是花费超过10分钟的时间.因此，我想尝试的任何解决方案都会花我一段时间.请帮忙.

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.

JUnit 是Java编程语言的单元测试框架.

JUnit is a unit testing framework for Java programming language.

JUnit在测试驱动的开发中很重要 开发.

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

首先，在项目级别修改您的build.gradle

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
}

重复

首先从build.gradle (模块级别)部分中删除compile files('libs/junit-4.12.jar').
