Error:Data Binding does not support Jack builds yet

Question

I am implementing DataBinding, it is working perfect, but it is not allowing me to use jackOptions. It throws error Data Binding does not support Jack builds yet while build.

Here is my build.gradle

android {


   defaultConfig {
       ...

       dataBinding {
           enabled true
       }

       jackOptions {
           enabled true
       }
   }

   compileOptions {
       sourceCompatibility JavaVersion.VERSION_1_8
       targetCompatibility JavaVersion.VERSION_1_8
   }
}

It seems like: *Data Binding does not support Jack builds **yet*** — Selvin, Jul 11 '16 at 09:32
@Selvin might be, i just want to confirm whether am i doing anything wrong or not. — Ravi, Jul 11 '16 at 09:33
@RRR can you check if your disable `jackOptions { enabled flase }` it work. — Harshad Pansuriya, Jul 19 '16 at 10:56
I can confirm, on my Android Studio 2.2 Beta install it doesnt work yet with DataBinding also — Kurovsky, Aug 12 '16 at 11:34
Seems like it wont be in AS 2.2 at all https://code.google.com/p/android/issues/detail?id=210615 — Kurovsky, Aug 19 '16 at 15:04

From yigit's comment it's clear that this functionality is still under development as he and George are project member of DataBinding.

we are working on it... yigit

I have also found that issue is already reported Issue 210615: Databinding with Jack compiler

UPDATE

2.3 will allow you to use data binding with jack but it still has limitations

Hmmm... still doesn't work. Is it expected to be release-ready? – IgorGanapolsky Aug 29 '16 at 20:05

Google will add support for Java 8 language features directly into the current javac and dx set of tools, and deprecate the Jack toolchain.

Check this out , Future of Java 8 Language Feature Support on Android

https://android-developers.googleblog.com/2017/03/future-of-java-8-language-feature.html

Updates:

Java 8 language features are now supported by the Android build system

Yesterday, we released Android Studio 2.4 Preview 6. Java 8 language features are now supported by the Android build system in the javac/dx compilation path. Android Studio's Gradle plugin now desugars Java 8 class files to Java 7-compatible class files, so you can use lambdas, method references and other features of Java 8.

Source : https://android-developers.googleblog.com/2017/04/java-8-language-features-support-update.html

Ok, but preview Android Studio builds are too risky for use for production projects. We need to wait for 2.4 stable. BTW Jack is sometimes extremely slow, compilation takes ages — user1209216, Jul 10 '17 at 12:28

As of gradle:2.2.0-alpha5, Jack builds are not yet compatible with DataBinding.

If you want to use data binding with Java 8, you can use retrolambda.

retrolambda doesn't do data binding does it? I never used it but it definitely seems out of scope for a lambda support library. – BillHaggerty Jul 25 '16 at 15:43

Retrolambda has nothing to do with databinding. – Chad Bingham Aug 24 '16 at 03:08

Though unrelated, Retrolambda IS compatible with databinding. – Jonas Alves Sep 20 '16 at 09:25
That wouldn't be Java 8, just a Java 8 simulated feature (and those lambdas are costlier in performance) – Leo supports Monica Cellio Sep 27 '16 at 18:12
