RxKotlin is not resolved properly after updating Gradle to 3.4.0

[AndroidPat]

Hi,
The new stable version of Android Studio suggest to update Gradle to 3.4.0 to get all the latest benefits.

After updating my Gradle from 3.3.2 ( wrapper 4.10.1 ) to 3.4.0 ( wrapper 5.1.1 ) the library is not resolved properly. That means all the references to rxKotlin in my project are not resolved. The behaviour is similar to commenting out the dependency in build.gradle.

Error examples:

• Unresolved reference: CompositeDisposable
• Unresolved reference: BehaviorSubject
• Unresolved reference: subjects
  library reference: implementation 'io.reactivex.rxjava2:rxkotlin:2.3.0'
  kotlin gradle plugin version: '1.3.31'

Steps to fix:

• project clean
• cache removal
• invalidate caches + restart
• remove build folder
• try in a different project

Same problem here with gradle plugin 3.4.1 and gradle wrapper 5.1.1. Also tried with gradle wrapper version 5.4.1 without luck.

Same issue here, I'm back to Gradle plugin 3.3.0 and Gradle wrapper 4.10.3

Hi all, thanks for reporting the issue. I've been crazy busy these days and I'll try to get back to the Rx libraries I own soon.

If you are still facing this issue, along with the dependency of rxKotlin use this

implementation 'io.reactivex.rxjava2:rxkotlin:x.y.z'
api 'io.reactivex.rxjava2:rxjava:2.2.0'

Only works for Gradle 5.0 or above. (If I am not wrong)

Is it planned some fix for this? Solutions here does not work for me

@FireZenk RxKotlin 2.4.0-beta.1 has just been released. Can you try it out and post a feedback whether the issue still persists or is gone?

I tried yesterday with this project, which uses RxKotlin version 2.1.0, and it's still not working.

Here are dependencies I am using,
RxKotlin : 2.1.0
RxAndroid : 2.0.1
Android Studio : 3.4.1
Kotlin : 1.3.40

For time being, I added io.reactivex.rxjava2:rxjava:2.0.2 to compile the project 👍

I too have this problem. Basic classes aren't being found like Single. The includes don't work. The IDE is able to read the cache but and find the Single declaration but the kotlin compiler can't. When I look at the tool bar, I noticed the cache is pointing to a cache directory titled file-2.1. I make an app and morphdevapp and they both fail. Maybe it should point to 2.2?

Workaround:
it works correctly with named params
UPD:
it was fixed by latest Kotlin plugin

[mamatagelanee07]

Which version of Kotlin Plug-In are you using?

[Jacks0N23]
