Gradle exists with non-zero value

Question

I'm working on an Adnroid app that was imported. The imported app used an old version of Gradle so I'm trying to sync it to the new ones (it used Gradle 19 I think). I'm unable to use Gradle 24 b/c there are symbol class finders that can't be found, so I'm just trying to get this working with 21, but it still won't work. Can anyone help?

Here is my outer .build file:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.3'
    }
}

allprojects {
    repositories {
        mavenCentral()
//        maven { url 'http://clinker.47deg.com/nexus/content/groups/public' }
//        maven { url 'http://repo1.maven.org/maven2' }
    }
}

Here is my inner .build file:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.0.0"

    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:support-v4:21.0.0'
    compile 'com.android.support:appcompat-v7:21.0.0'
//    compile "com.android.support:support-core-utils:21.0.0"
    compile 'com.j256.ormlite:ormlite-core:4.48'
    compile 'com.j256.ormlite:ormlite-android:4.48'
    compile 'se.emilsjolander:stickylistheaders:2.5.2'
    compile 'com.github.chrisbanes.photoview:library:1.2.2'
    compile 'com.loopj.android:android-async-http:1.4.6'
    compile 'com.google.android.gms:play-services:6.1.71'
}

When I run this on an physical android I get this error:

I can't figure out what's wrong with it. Can anyone help?

Answer 1

 dependencies {
        classpath 'com.android.tools.build:gradle:2.1.3'
    }

You're using gradle plugin 2.1.3 which according to documentation needs the following as must have dependencies.

Android Plugin for Gradle, Revision 2.1.3 (August 2016)

Dependencies:

    Gradle 2.14.1 or higher.
    Build Tools 23.0.2 or higher.

This update adds compatibility with Gradle 2.14.1, which includes performance improvements, new features, and an important security fix.

For more details, see the Gradle release notes.

whereas your build tool version currently set as buildToolsVersion "21.0.0". Change the build tool version to 23.0.2, update the support and appcompat dependencies accordingly and sync again.
