Question

I get the following error when I try to build a release build. I am using Android 2.3. I added my gradle and proguard rule files below and I use mac with mac os X

Error:Execution failed for task ':app:packageRelease'. > java.io.IOException: Failed to read zip file '/Users/username/Documents/Android Projects/Project Name/app/build/intermediates/transforms/proguard/release/jars/3/1f/main.jar'. 

Proguard rule file

 -keepclassmembers class * { @android.webkit.JavascriptInterface <methods>; } -keepattributes JavascriptInterface -keepattributes *Annotation* -dontwarn com.razorpay.** -keep class com.razorpay.** {*;} -optimizations !method/inlining/* -keepclasseswithmembers class * { public void onPayment*(...); } -keep @interface butterknife.* -keepclasseswithmembers class * { @butterknife.* <fields>; } -keepclasseswithmembers class * { @butterknife.* <methods>; } -keepclasseswithmembers class * { @butterknife.On* <methods>; } -keep class **$$ViewInjector { public static void inject(...); public static void reset(...); } -keep class **$$ViewBinder { public static void bind(...); public static void unbind(...); } -keep class com.google.common.** {*;} -dontwarn sun.misc.Unsafe -dontwarn javax.annotation.**

gradle project level

 // Top-level build file where you can add configuration options common to all sub-projects/modules. buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:2.3.0' // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } } allprojects { repositories { jcenter() maven { url 'https://dl.bintray.com/leaking/maven' } } } task clean(type: Delete) { delete rootProject.buildDir } 

Answer 1

This issue is mentioned here , which occurs in the project, including non-ASCII class names. The issue will be addressed with version 2.4 of the Android gradle plugin (not yet released at the moment).

An alternative is to switch to 2.2.3:

 classpath 'com.android.tools.build:gradle:2.2.3' 

Answer 2

For me, this error occurred when I was building a project on Windows, where write access was granted only to admin users, and Android Studio was running in normal mode (not in administrator mode). When I launched Android studio with "Run as administrator", write access was available and .apk was generated successfully.
