Proguard warnings on 1.3.0-M1 with flows

[kaserdan]

Proguard rules applied from coroutines.pro
After upgrating to 1.3.0-M1 I got these warnings:

Warning: kotlinx.coroutines.flow.ChannelFlowMerge$mergeImpl$$inlined$collect$1$1: can't find enclosing method 'java.lang.Object emit$$forInline(java.lang.Object,kotlin.coroutines.Continuation)' in program class kotlinx.coroutines.flow.ChannelFlowMerge$mergeImpl$$inlined$collect$1
Warning: kotlinx.coroutines.flow.FlowKt__BuildersKt$asFlow$$inlined$unsafeFlow$1$1: can't find enclosing method 'java.lang.Object collect$$forInline(kotlinx.coroutines.flow.FlowCollector,kotlin.coroutines.Continuation)' in program class kotlinx.coroutines.flow.FlowKt__BuildersKt$asFlow$$inlined$unsafeFlow$1
Warning: kotlinx.coroutines.flow.FlowKt__ContextKt$$special$$inlined$collect$1$1: can't find referenced class kotlinx.coroutines.flow.FlowKt__ContextKt$$special$$inlined$collect$

Are they safe to ignore?

[elizarov]

Yes. I'm not sure why would ProGuard complain about that and what can we do about it. It looks like ProGuard bug to me.

[ilmirus]

This is a compiler bug: https://youtrack.jetbrains.com/issue/KT-31242. It is fixed in 1.3.40. Until then, IMHO, it is safe to ignore them.

[qwwdfsad]

Fixed in 1.3.0-M2

[CrisBarreiro]

I'm still facing the same issue after updating to 1.3.0-M2

[qwwdfsad]

@CrisBarreiro could you please attach a reproducer?

I've verified, the bytecode does not have references to eliminated state machines (at least, in my setup)

Facing similar issue with Flows
Warning: com.my.app.MyViewModel$1$invokeSuspend$$inlined$collect$1$1: can't find enclosing method 'java.lang.Object emit$$forInline(java.lang.Object,kotlin.coroutines.Continuation)' in program class com.my.app.MyViewModel$1$invokeSuspend$$inlined$collect$1

In code:
myInteractor.myFlow() .filterNotNull() .collect { }

[amankgo]

Any solution to this?

[elizarov]

@jemshit What Kotlin version are you using?

[sateeshb]

Hi
i am also facing the same issue. i am using the kotlin version 1.3.41.

[elizarov]

Can you provide a simple project that reproduces the problem?

[jemshit]

kotlin 1.3.50, Android Studio 3.5 (with latest kotlin plugin)

[aosa4054]

I am also facing this issue.
In my project, using Kotlin 1.3.50, just implementing org.jetbrains.kotlinx:kotlinx-coroutines-android:1.3.0 or org.jetbrains.kotlinx:kotlinx-coroutines-core:1.3.0 produces the proguard warning even if i don't use some Flow operators in Kotlin files. I've not led to reproduce it in simple project yet.

[jschear]

Here's an Android Studio project that reproduces the issue when ./gradlew assembleRelease is run. (It's a new project, the only changes I made were to add org.jetbrains.kotlinx:kotlinx-coroutines-android:1.3.0 as a dependency, turn on minification for release builds, and add android.enableR8=false to gradle.properties in order to use proguard instead of R8.)

CoroutinesProguardIssue.zip

[elizarov]

@jschear Thanks a lot. I've updated https://youtrack.jetbrains.com/issue/KT-31242 that had, indeed, regressed.

[pana777]

in proguard-rules just add: -dontwarn kotlinx.coroutines.flow.**

[shmuelr]

I think you can be more specific with the proguard rule. I believe the only issues here are the inlined functions.
-dontwarn kotlinx.coroutines.flow.**inlined**

[pana777]

yeah you are right

[ZakTaccardi]

5 months without a fix for https://youtrack.jetbrains.com/issue/KT-31242 is pretty painful.

@elizarov - any chance you could apply some pressure to get the timeline for fixing this sped up? It has the unfortunate side effect of making Coroutines/Flow look bad (flow heavily uses inline/crossinline), even though this is not the fault of the Coroutines lib

[elizarov]

@ZakTaccardi KT-31242 was just recently reopened. Work in progress.

[sebastianharder]

What's the workaround until the issue is fixed?
Neither -dontwarn kotlinx.coroutines.flow.**inlined** nor -dontwarn kotlinx.coroutines.flow.** work for me. But I can also wait for Kotlin 1.3.70. The latest EAP version worked already.

[digitalbuddha]

Besides the above rules I had to add the following:

-dontwarn kotlinx.coroutines.reactive.** otherwise I was getting:

Warning: kotlinx.coroutines.reactive.FlowSubscription$consumeFlow$$inlined$collect$1$1: can't find enclosing method 'java.lang.Object emit$$forInline(java.lang.Object,kotlin.coroutines.Continuation)' in program class kotlinx.coroutines.reactive.FlowSubscription$consumeFlow$$inlined$collect$1

Whatever the fix is, kindly fix the reactive bindings as well. Thank you!

[qwwdfsad]

@digitalbuddha could you please check whether the problem reproduces on the latest 1.3.70-eap?
The companion kotlinx.coroutines version is 1.3.3-1.3.70-eap-42

[JakeWharton]

Note that you'll need to compile this library with 1.3.70 eap and then consume that to confirm.

[hongsigi]

Exists in v1.3.70-eap-184

[JakeWharton]

And to be clear, you've compiled the kotlinx.coroutines library yourself using 1.3.70 and then consumed it in your app and it still produces that warning?

Or have you only bumped your app to 1.3.70 and consumed the released version of kotlinx.coroutines?

[vivekwolf123]

Is there any workaround for this issue?
Tried -
-dontwarn kotlinx.coroutines.flow.**inlined** and also -dontwarn kotlinx.**.**. But no luck :(

[markdingram]

This appears fixed (at least for me) with Kotlin 1.3.70 & Coroutines 1.3.4

[SoNep]

I use Kotlin 1.3.70 & Coroutines 1.3.4 but still have
can't find enclosing method 'java.lang.Object collect$$forInline(kotlinx.coroutines.flow.FlowCollector,kotlin.coroutines.Continuation)' in program

[qwwdfsad]

@SoNep could you please provide a reproducer?

[SoNep]

flow.mapNotNull{}
in dynamic module.
use proguarg, no R8
I sort out with -dontwarn this file

[qwwdfsad]

Could you please elaborate on whether it is still a problem with coroutines 1.5.0 and the latest R8?
