Android Question

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

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.

Answer

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.+'
