Gradle plugin 1.4.0-beta6 doesn't work with minification and repackageclasses option

Question

Plugin version: com.android.tools.build:gradle:1.4.0-beta6 Build type config:

buildTypes {
    release {
        minifyEnabled true
        shrinkResources true
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-project.txt'
    }
}

minSdkVersion 9
targetSdkVersion 23
useLibrary 'org.apache.http.legacy'
compileSdkVersion 23
buildToolsVersion '23.0.1'

The build cannot be finished because of exception in gradle task. This is extremaly important, because class repackaging fixes many issues on Samsung devices with precompiled support library sources.

Error: :myHeart:transformClassesAndResourcesWithProguardForGooglePlayRelease FAILED

FAILURE: Build failed with an exception.

• What went wrong: Execution failed for task ':myHeart:transformClassesAndResourcesWithProguardForGooglePlayRelease'.

  java.io.IOException: Can't write [H:\Projekty\my-heart\myHeart\build\intermediates\transforms\CLASSES_and_RESOURCES\FULL_PROJECT\proguard\GooglePlay\release] (Can't read [H:\Projekty\my-heart\myHeart\build\intermediates\classes\GooglePlay\release] (H:\Projekty\my-heart\myHeart\build\intermediates\transforms\CLASSES_and_RESOURCES\FULL_PROJECT\proguard\GooglePlay\release\happy\hacking\con.class (The system cannot find the file specified)))

• Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

proguard file:

-repackageclasses 'happy.hacking'

-keep class android.support.v4.app.** { *; }
-keep interface android.support.v4.app.** { *; }

-keep class android.support.v7.app.** { *; }
-keep interface android.support.v7.app.** { *; }

-keep class android.support.v13.app.** { *; }
-keep interface android.support.v13.app.** { *; }


#To remove debug logs:
-assumenosideeffects class android.util.Log {
    public static *** d(...);
    public static *** v(...);
    public static *** w(...);
}

-renamesourcefileattribute SourceFile
-keepattributes SourceFile,LineNumberTable

Thanks to IntelliJ Amiya it turned out that 1.4.0-beta6 is buggy, but 1.4.0-beta4 works totally fine.
