rest - Android with Gradle (Java finished with non-zero exit value 2)

Question

This is my .gradle file:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.test.test"
        minSdkVersion 15
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    packagingOptions {
        exclude 'META-INF/license.txt'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/NOTICE'
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.3'

    compile 'com.mcxiaoke.volley:library:1.0.15'
    compile 'org.glassfish.jersey.media:jersey-media-json-jackson:2.17'
}

When I try to run my Android app, I get the next error:

Error:Execution failed for task ':app:dexDebug'.

com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/usr/lib/jvm/java-8-oracle/bin/java'' finished with non-zero exit value 2

I get this error when I add to gradle file the jackson library. Googling some time, I've found that jackson library is compatible with android apps, and It's faster than other libraries as gson.

How I can solve it? I'm an Android beginner.

I think you should change your java JDK change jvm v8 for jdk7. This link can help you: Is it possible to use Java 8 for Android development?

Other possible issue its dependency error, clean gradle before build. And change your jackson library for this:

compile 'com.fasterxml.jackson.core:jackson-databind:2.2.+'
compile 'com.fasterxml.jackson.core:jackson-core:2.2.+'
compile 'com.fasterxml.jackson.core:jackson-annotations:2.2.+'
