app:dexDebug error in build.gradle Android Studio

I am receiving the app:dexDebug error when trying to run my project on Android Studio. I believe it's got to do with my dependencies but I am not sure where I am going wrong.
The error is:
Error:Execution failed for task ':app:dexDebug'.
com.android.ide.common.process.ProcessException:
org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.7.0_17\bin\java.exe'' finished with non-zero exit value 2
My dependencies in the build.gradle file are as follows:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.2.1'
compile 'com.android.support:design:23.2.1'
compile 'com.facebook.android:facebook-android-sdk:[4,5)'
compile 'com.google.android.gms:play-services:8.3.0'
compile 'org.springframework.android:spring-android-rest-template:1.0.1.RELEASE'
compile 'com.fasterxml.jackson.core:jackson-databind:2.3.2'
}
Can anyone point me in the correct direction here, please.
Thank you.
UPDATE
Problem solved by adding the following to my build.gradle
packagingOptions {
exclude 'META-INF/license.txt'
exclude 'META-INF/LICENSE'
exclude 'META-INF/notice.txt'
exclude 'META-INF/NOTICE'
}

Android Studio Error:Execution failed for task ':app:dexDebug' to solve it setting multiDexEnabled to true in your gradle file.
defaultConfig {
// Enabling multidex support.
multiDexEnabled true
}

The problem is most likely caused by adding all play services dependencies. You should not compile the entire package of APIs into your app, it increases the number of methods in your app. app:dexDebug error indicates you have exceeded the 65k method limit. Remove this line in your build.gradle: compile 'com.google.android.gms:play-services:8.3.0'
then choose from these seperate dependencies, the ones to add based on what your app needs. E.g to use Gcm, you only need to add compile 'com.google.android.gms:play-services-gcm:8.4.0'

Build failed while builing in release mode

I am trying to generate signed build but it shows the below error:

If your code works fine without the missing classes, you can suppress

I tried rebuild/clean build option but still I am getting the same error everytime.
My project has following dependencies:

}
Please suggest how to fix the above issue. Thanks.

It looks like ProGuard may be stripping out the classes that your build relies on. Try doing a release build with ProGuard disabled (minifyEnabled false) and see if that works. If this works then you need to configure your ProGuard rules to not strip out the types your code relies on.

I solved the issue by adding -ignorewarnings at the top of my proguard rule file.

Try adding packagingOptions to the gradle, try cleaning the project,delete the build folder and rebuild again,Specify all the jar files u have used in gradle.
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.1"

From error i can say you'll have to add the following gradle dependency :
compile 'com.android.support:recyclerview-v7:+'
EDIT:
Error:Execution failed for task ':app:dexDebug'. >
com.android.ide.common.process.ProcessException:
org.gradle.process.internal.ExecException: Process 'command

For this error i think you are compiling JAR library twice. You are using
compile fileTree(dir: 'libs', include: ['*.jar'])
in build.gradle file so it will compile all library that has jar extension on libs folder, so You can remove this lines:
compile 'com.squareup.picasso:picasso:2.3.2'
compile 'com.nineoldandroids:library:2.4.0'
compile 'com.daimajia.slider:library:1.1.5#aar'
If issue still exists then issue is quite possibly due to exceeding the 65K methods dex limit imposed by Android. This problem can be solved either by cleaning the project, and removing some unused libraries and methods from dependencies in build.gradle, OR by adding multidex support.
defaultConfig {
// Enabling multidex support.
multiDexEnabled true
}

Did you forget the version? In your gradle config you should have something like this:
compile 'com.android.support:recyclerview-v7:23.0.1'

In my case, I deleted caches folder inside .gradle folder and then I added compile. It worked for me!

Duplicate entry using Parse and Multidex

My project is a Chat app that uses Parse. After added other dependencies, this problem started appearing:
Error:Execution failed for task ':app:dexDebug'.
com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/usr/lib/jvm/java-7-oracle/bin/java'' finished with non-zero exit value 2
Searching here in StackOverflow, some folks told me that it could be the 65K limit from Android.
So, to solve I followed the steps below:
1 - Add Multidex
DefaultConfig {
         multiDexEnabled true
}
and
compile 'com.android.support:multidex:1.0.0'
https://developer.android.com/tools/building/multidex.html
2 - Enable Jumbo Mode in Android Gradle Settings
dexOptions {
jumboMode = true
}
I cleaned the project and ran the gradle build. It did not generate any errors. Great! But when I click "Run app" it generates this error below.
Error: Execution failed for task ': app:
packageAllDebugClassesForMultiDex'. > Java.util.zip.ZipException:
duplicate entry: bolts / AggregateException.class
If I remove the dependency 'com.parse.bolts: bolts-android: 1. +' the "Run app" works, but I can not do without the dependency of Parse.
This is my Gradle build script:
apply plugin: 'com.android.application'

buildToolsVersion "22.0.1"
defaultConfig {
applicationId "br.com.triangulum.mink"

}

}

try to change this:
compile('com.android.support:multidex:1.0.0') {
exclude group: 'com.parse.bolts',
module: 'bolts-android'
}
To this:
compile('com.android.support:multidex:1.0.0');
the bolds module is used sometimes to fix Duplicated dexLibs

Your com.facebook.android:facebook-android-sdk:4.1.0 library is messing with parse as both use same bolts-android module internally and having a different version of this module. Try to exclude this module from any of parse or facebook gradle dependency.
compile('com.facebook.android:facebook-android-sdk:4.1.0') {
exclude group: 'com.parse.bolts',
module: 'bolts-android'
}
I was having the same problem and When I run ./gradlew yourModuleName:dependencies by the terminal, I found exactly which two libraries are messing with each other having a different version of the same module internally.

Error:Execution failed for task ':app:dexDebug'. > com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException:

Error:Execution failed for task ':app:dexDebug'. > com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/Library/Java/JavaVirtualMachines/jdk1.8.0_40.jdk/Contents/Home/bin/java'' finished with non-zero exit value 2
I'm getting the above exception. I think the problem is in my build.gradle.
My build.gradle dependencies is:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.0.0'
compile 'com.google.android.gms:play-services:7.3.0'

compile 'me.villani.lorenzo.android:android-cropimage:1.1.0'
compile 'com.oguzdev:CircularFloatingActionMenu:1.0.2'
}

This error is due to a limitation of the Dalvik Executable (dex) bytecode file. Because of the number of dependencies in your project you have reached the 65K method limit. Meaning that the Dalvik Executable can only reference 65,536 methods and you have surpassed this limit. These methods includes methods within the Android libraries, any methods within your dependencies and your own methods in which you have written.
To get passed this limitation you can enable multiDex within the build.gradle file which will create more than one Dalvik Executable file.
android {
compileSdkVersion 21
buildToolsVersion "21.1.0"
defaultConfig {
...
minSdkVersion 14
targetSdkVersion 21
...
// Enabling multidex support.
**multiDexEnabled true**
}
...
}
Before enabling multidex make sure all dependencies are needed. You can use ProGuard http://developer.android.com/tools/help/proguard.html to automatically remove unused dependencies from your build.

You can check "libs" folder.
compile fileTree(dir: 'libs', include: ['*.jar'])
This code can import all of the package in "libs".If your "libs" have package,you don't need to compile again.And if you compile 'v7',you can't compile 'v4'.If you "libs" have "v4",delete it.
