How to use Realm database with Java 8 features

Question

I am new to using Realm database for Android.

I modified my gradle files to include the Jack toolchain so that I could use Java 8 language features. I also modified the gradle files to install the Realm plugin. When I synced the project gradle files, I received the following error: Error:Could not find property 'options' on task ':app:compileDebugJavaWithJack'. The two modifications work fine on their own, but for some reason I cannot have both at the same time.

I would very much appreciate help on this matter.

It is not possible to use Jack compiler with Realm at the moment, because Jack does not support bytecode manipulation (Javassist / Transform API).

In order to use lambdas, it's easier for you to use Retrolambda instead for the time being.

buildscript {
     //...
     dependencies {
        classpath "io.realm:realm-gradle-plugin:1.1.0"
        classpath 'me.tatarka:gradle-retrolambda:3.2.5'
    }
}

And

apply plugin: 'me.tatarka.retrolambda'
apply plugin: 'realm-android'

android {
    ...

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

Aw, that's a shame. Thanks for your response regardless. – novice Aug 01 '16 at 19:23 — novice, Aug 01 '16 at 19:23

Unfortunately Jack compiler and Realm can't play together right now. Please follow that topic. That one is also useful.
