Question

Error:Execution failed for task ':app:transformClassesWithDexForDebug'. com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:Program FilesJavajdk1.7.0_79injava.exe'' finished with non-zero exit value 1

Here is my gradle build file:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "br.com.gerenciarsc.nfce"
        minSdkVersion 12
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile('org.simpleframework:simple-xml:2.7.1') {
        exclude group: 'xpp3', module: 'xpp3'
        exclude group: 'stax', module: 'stax-api'

I faced the same issue. Scrolling down, I found the following error in the logs:

java.lang.UnsupportedClassVersionError: com/android/dx/command/Main : Unsupported major.minor version 52.0

Then I searched for the above error and found the following work-around as suggested by the solutions to this question and another similar question:

In the file build.gradle(Module:app) I changed the following from:

buildToolsVersion "24.0.0"

to

buildToolsVersion "23.0.2"

and clicked the button to "sync project with gradle files" in Android Studio and the error vanished.

Note: I didn't understand the exact reason for the error and it's solution completely but it seems to be a compatibility issue of java version 1.7 and Android API level 24. Some people suggested (on the questions' links I mentioned) to use JDK version 8 with API 24, or downgrade it to JDK version 7 and API level 23.0.x as a work around.
