Android Gradle sync failed (import project from github)

Hi guys i download a project from github and i imported in android studio , after imported am getting error

Gradle sync failed: Cause: assert localProps['keystore.props.file']
       |         |
       |         null
       [ndk.dir:E:\sdk\ndk-bundle, sdk.dir:E:\sdk]
       Consult IDE log for more details (Help | Show Log)

Gradle File:

signingConfigs {
    release {
        def Properties localProps = new Properties()
        localProps.load(new FileInputStream(file('../local.properties')))
        def Properties keyProps = new Properties()
        assert localProps['keystore.props.file'];
        keyProps.load(new FileInputStream(file(localProps['keystore.props.file'])))
        storeFile file(keyProps["store"])
        keyAlias keyProps["alias"]
        storePassword keyProps["storePass"]
        keyPassword keyProps["pass"]

buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), file('proguard-project.txt')
        signingConfig signingConfigs.release

    publicBeta {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), file('proguard-project.txt')
        versionNameSuffix " Beta " + versionProps['betaNumber']

    publicDebug {
        debuggable true
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), file('proguard-project.txt')
        versionNameSuffix " Debug Beta " + versionProps['betaNumber']


I realy don't know what to do.

Does anyone have any suggestions?.

In the root folder of your project, you should have keystore.properties and local.properties files.

keystore.properties should have something like this:


In local.properties, add the last line.

# Add the line below

See a commit here or check the modified project.

Or if you need a quick dirty fix, just make the gradle script the same as a standard one by replacing the android block with this:

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        minSdkVersion rootProject.ext.minSdkVersion
        targetSdkVersion rootProject.ext.targetSdkVersion

        versionCode 1
        versionName "1.0"

    lintOptions {
        abortOnError false

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7

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

When I got such an error, it was because I was using JDK8, while the imported github repo was using JDK7.

Also make sure you have "Android Support Repository" installed from SDK Manager > Extras.
