Failed to resolve : Error:(23, 17) junit:junit:4.12 in android studio 1.4 [duplicate]

Answer 1

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

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

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

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

Following should work:

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'
}

Answer 2

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

buildscript {
    [...]
}

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

Answer 3

1. go to the android studio libs directory (C:\Program Files\Android\Android Studio\lib)
2. find junit-4.12.jar file
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.gradle file

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)
