Android Studio 2.2 and Jack are getting blocked by

Question

So I update my project to use the new jack compiler, but for some unknown reason my AntiVir blocks the task transformClassesWithPreJackPackagedLibrariesForDebug It works if I disable AntiVir real-time protection. I really don't want to do that and I don't want to start putting my android project in the exception list.
I am using Android Studio 2.2 and this is my build.gradle

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.2"
    defaultConfig {
        minSdkVersion 21
        targetSdkVersion 24
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        jackOptions {
            enabled true
        }
     compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
     }
}

My project.gradle

buildscript { 
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.0'
    }
}

And the error when I try to run the app on my hardware device.

Error:Execution failed for task ':app:transformClassesWithPreJackPackagedLibrariesForDebug'.

Answer 1

Fixed using 'com.android.tools.build:gradle:2.2.0-alpha5'

if not working than please add your Android SDK, Android Studio and project folders to your antivirus whitelist:

Answer 2

While compiling disable real-time protection in your anti-virus package. It is the only workaround that is reliable at this time.

Answer 3

You could add your Android SDK, Android Studio and project folders to your antivirus whitelist. This way you will still be protected while building.
