Steps & Code to Reproduce

It's a complicated build, but here are my app plugins:

apply plugin: 'com.android.application'
apply plugin: 'com.neenbedankt.android-apt'
apply plugin: 'me.tatarka.retrolambda'
apply plugin: 'io.fabric'
apply plugin: 'realm-android'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

I wonder if maybe the ordering is important starting in 2.0?

Code Sample

Version of Realm and tooling

Realm version(s): 2.0.0

Android Studio version: 2.2.0

Gradle version: 3.1

Android Gradle Plugin version: 2.2.0

Which Android version and device: N/A

Most helpful comment

Note, this only seems to happen if you have a library project at the same time. So using databinding in a single project with Realm should work fine.

Hi @tbsandee
Thank you for reporting the first bug of 2.0.

I think this line
https://github.com/realm/realm-java/blob/master/gradle-plugin/src/main/groovy/io/realm/gradle/Realm.groovy#L75 is the cause of this problem.

I'll try to reproduce and fix it.

I have the same problem

hateum picture hateum on 29 Sep 2016

I couldn't reproduce this.
Could you provide whole project?

zaki50 picture zaki50 on 29 Sep 2016

@tbsandee @AleksanderMielczarek @hateum We are not able to reproduce this on our side, at least not with the information given. Can you produce a minimal example that makes your projects fail?

cmelchior picture cmelchior on 29 Sep 2016

@cmelchior I've created example project https://github.com/AleksanderMielczarek/Realm2Gradle3Issue.

I've noticed that for me problem occurs when Realm is used in library module and databinding in project is enabled.

AleksanderMielczarek picture AleksanderMielczarek on 29 Sep 2016

@AleksanderMielczarek Thank you very much. I can reproduce it from your example now. We will take a closer look

cmelchior picture cmelchior on 29 Sep 2016

I think I have narrowed the problem down to databinding. If you disable databinding, the projects will compile just fine. Still trying to figure out why this is happening.

cmelchior picture cmelchior on 29 Sep 2016

@cmelchior that's weird because I used databinding with Realm before in 1.2.0 and it worked.

I wonder what changed.

We are manipulating the dependencies in our Gradle plugin to support:

realm {
 syncEnabled = true
}

But right now it is still unclear if we are doing something wrong or Google Android Plugin is.

cmelchior picture cmelchior on 29 Sep 2016

Note, this only seems to happen if you have a library project at the same time. So using databinding in a single project with Realm should work fine.

@cmelchior wow. Now that is cryptic.

Zhuinden picture Zhuinden on 29 Sep 2016

@tbsandee @hateum @AleksanderMielczarek This is the preliminary findings:

  • It only seems to be a problem if you combine databinding, Realm 2.0, and gradle 3.1.

Doing any of the following fixes it:

1) Don't use a library project with Realm
2) Use Gradle 2.14.1 instead
3) Disable databinding

For now it seems the easiest option is dropping back down to Gradle 2.14.1

cmelchior picture cmelchior on 29 Sep 2016

@cmelchior thanks for investigating.

For the record, I don't use databinding and still get this error. I do use android-apt, retrolambda, kotlin and fabric and use a few internal library projects as well. None of the library projects use Realm, however.

I _am_ using Gradle 3.1.

I'll try to narrow my project down so that there's another example, but it may be a couple days. Looks like you've got your hands full over there -- looking forward to an exciting Realm 2.x experience!

There is also a bug tracking this on the Google BugTracker here: https://code.google.com/p/android/issues/detail?id=220031

cmelchior picture cmelchior on 29 Sep 2016

I have the same problem.

  • I don't use databinding
  • I use Gradle 3.1
  • I migrate realm from 1.2 to Realm 2.0

If I change distributionUrl in gradle-wrapper.properties to gradle-2.14.1-all.zip everythink works perfect.

I'm trying to avoid using DependencyResolutionListener to solve this.

zaki50 picture zaki50 on 3 Oct 2016

I created a PR (#3547) that fixes this.

zaki50 picture zaki50 on 3 Oct 2016

fixed in 2.0.1
