android studio execution failed for task app dexdebug command finished with non zero value 1

Had a similar problem solved it by adding two lines to the top of the build.gradle files:

sourceCompatibility=JavaVersion.VERSION_1_7 targetCompatibility=JavaVersion.VERSION_1_7

If you're using the experimental gradle plugin do this:

apply plugin: 'com.android.model.application'
sourceCompatibility=JavaVersion.VERSION_1_7
targetCompatibility=JavaVersion.VERSION_1_7

model {
    android {
        ...

Otherwise it's something like this:

android {
    compileSdkVersion 22
    buildToolsVersion "23.0.0 rc3"
    ...
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
    ...

*Make sure to go through all the build.gradle files and add the JavaVersion to any that have "model" or "android" in them

I had this problem too, but fixed it. I assumed that everything was due to the Estimote library which I updated to a new version that comes in AAR format only.

Turns out, I had other dependencies being responsible for this. These did not cause any problems with the previous version that was a JAR.

In my case, I've included parse-bolts twice. Everything works great since I removed one of the lines in my build.gradle

It happens to me as well just after updating the Android studio.

I solved it by

1. "Build" --> "Clean Project"
2. "Build" --> "Rebuild Project"

Good luck.

Check that you don't add this library twice.
