If you are adding them to buildscript you will get an error.

如果您将它们添加到 buildscript，您将收到错误消息。

It is a difference between the buildscript repository and the repositories for the dependencies. The buildscript is used for gradle build dependencies.

这是 buildscript 存储库和依赖项存储库之间的区别。buildscript 用于 gradle 构建依赖项。

You will need to add the following to your build.gradle file and it should work fine.

您需要将以下内容添加到 build.gradle 文件中，它应该可以正常工作。

repositories {
    maven { url 'http://repo1.maven.org/maven2' }
    jcenter { url "http://jcenter.bintray.com/" }
}

Following should work:

以下应该工作：

apply plugin: 'com.android.application'

repositories {
    maven { url 'http://repo1.maven.org/maven2' }
    jcenter { url "http://jcenter.bintray.com/" }
}

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "com.example.application"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {

        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
}

For me it was that allprojects section was missing in the top level gradle build file:

对我来说，顶级 gradle 构建文件中缺少 allprojects 部分：

buildscript {
    [...]
}

allprojects { // <-- required!!!
    repositories {
        jcenter()
    }
}

1. go to the android studio libs directory (C:\Program Files\Android\Android Studio\lib)
2. find junit-4.12.jarfile
3. copy the jar file to your project libs folder (myproject\app\libs)
4. open android studio and delete(comment) this line (testCompile 'junit:junit:4.12')in build.gradlefile

5. in android studio open (libs) directory and right click the jar file then choose add as a library

6. just build your project (for more info see below picture)

1. 转到android studio libs目录 (C:\Program Files\Android\Android Studio\lib)
2. 查找junit-4.12.jar文件
3. 将 jar 文件复制到您的项目 libs 文件夹中 (myproject\app\libs)
4. 打开Android工作室和删除（注释）这一行 (testCompile 'junit:junit:4.12')的build.gradle文件

5. 在android studio中打开（libs）目录并右键单击jar文件然后选择 add as a library

6. 只需构建您的项目（有关更多信息，请参见下图）
