Exception parsing classes : realm-optional-api

[osayilgan]

Hi,

Right after the update to Realm 1.0.1 from 0.82, I started getting this Exception below. I tried building my project with Android Studio 2.1 and 2.2-Preview3 but the result is the same. Any idea why this is happening ?

I'm using RetroLambda so the compiler options is as below:

compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8 
}

Thanks.

Android Studio : 2.2 Preview3
Gradle Version : 2.13
Android Gradle Plugin : 2.1.0 (tried with 2.2.0-alpha3 as well)
compileSdkVersion : 23
buildToolsVersion : 23.0.3

The related transformer has been disabled by #3028 . You could try the snapshot (probably still need a few hours for snapshot release to include it) before we release it.

@beeender , what is the latest version includes this fix ? Snapshot still seems to be 1.1.0-SNAPSHOT in version.txt file.

[beeender]

@osayilgan It is 1.1.0-SNAPSHOT, it should contain the fix.
