Error converting bytecode to dex: Cause: java.lang.RuntimeException: Exception parsing classes - Android studio 2.0 beta 6

Question

I updated to the last version of Android studio 2.0 Beta 6 with the gradle :

dependencies {     classpath 'com.android.tools.build:gradle:2.0.0-beta6' } 

The app works perfectly fine on emulator and devices I tested every thing and it works fine.

I got many errors only when I try to Generate Signed APK,

I got some errors in dependencies, all of them solved when i excluded vector drawable, vector animate drawable and Support-v4 library

Now i dont have any dependencies error.

now my gradle.build for the app module looks like this:

apply plugin: 'com.android.application'  android {     configurations {         //all*.exclude group: 'com.android.support', module: 'support-v4'         all*.exclude module: 'animated-vector-drawable'         all*.exclude module: 'support-vector-drawable'         //all*.exclude module: 'support-v4'      }     repositories {         maven { url "https://jitpack.io" }      }     compileSdkVersion 23     buildToolsVersion '23.0.2'     defaultConfig {         applicationId "com.test.test"         minSdkVersion 11         targetSdkVersion 23         versionCode 1         versionName "1"  //        multiDexEnabled true         vectorDrawables.useSupportLibrary = true     }     buildTypes {         release {             minifyEnabled true             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'         }     }     productFlavors {     }  }  dependencies {     compile fileTree(dir: 'libs', include: ['*.jar'])      compile('com.github.afollestad.material-dialogs:commons:0.8.5.5@aar') {         transitive = true         exclude module: 'support-v4'         exclude module: 'appcompat-v7'         exclude module: 'recyclerview-v7'     }     compile('com.google.android.gms:play-services-ads:8.4.0') {         exclude module: 'support-v4'     }     compile('com.google.android.gms:play-services-analytics:8.4.0') {         exclude module: 'support-v4'     }     compile('com.android.support:appcompat-v7:23.2.0') {         exclude module: 'support-v4'         exclude module: 'animated-vector-drawable'         exclude module: 'support-vector-drawable'     }     compile('com.android.support:support-v4:23.2.0') {         exclude module: 'animated-vector-drawable'         exclude module: 'support-vector-drawable'     }     compile('com.android.support:palette-v7:23.2.0') {         exclude module: 'support-v4'     }     compile('com.android.support:cardview-v7:23.2.0') {         exclude module: 'support-v4'     }     compile('com.android.support:recyclerview-v7:23.2.0') {         exclude module: 'support-v4'     }     compile('com.android.support:design:23.2.0') {         exclude module: 'support-v4'     }     compile('com.nineoldandroids:library:2.4.0') {         exclude module: 'support-v4'     }     compile('com.baoyz.swipemenulistview:library:1.2.1') {         exclude module: 'support-v4'         exclude module: 'appcompat-v7'         exclude module: 'recyclerview-v7'     }     compile('com.squareup.picasso:picasso:2.5.2') {         exclude module: 'support-v4'     }     compile('com.nononsenseapps:filepicker:2.5.0') {         exclude module: 'support-v4'         exclude module: 'appcompat-v7'         exclude module: 'recyclerview-v7'      }     compile 'com.google.code.gson:gson:2.6.1' } 

The errors shows up only when I build for release:

This is the error when i turn on multiDex:

Error:Execution failed for task ':app:transformClassesWithMultidexlistForRelease'. > com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home/bin/java'' finished with non-zero exit value 1 

And this is the error when i turn it off:

:app:transformClassesWithDexForRelease Error:Error converting bytecode to dex: Cause: java.lang.RuntimeException: Exception parsing classes  Error:Execution failed for task ':app:transformClassesWithDexForRelease'.  > com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home/bin/java'' finished with non-zero exit value 1 

I tried to change the buildToolsVersion '23.0.2' to every possible version and nothing changed.

when i put the version 22.0.1 i got this error:

Error:Error converting bytecode to dex: Cause: com.android.dx.cf.iface.ParseException: name already added: string{"a"}  Error:Execution failed for task ':app:transformClassesWithDexForRelease'. > com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home/bin/java'' finished with non-zero exit value 1 

I tried with all possible support libraries version and same result.

I tried with Java 1.6 and 1.7 and nothing has changed !

what can be other possible solution please ?

Answer 1

just do Build > Clean Project Wait for Cleaning Ends and then Build > Rebuild Project, and the error was gone. that's it.
