OkHttp: NoSuchMethodError copyInto in TlsUtil - kotlin

Question

Running instrumentation tests with RESTMock we are getting this error
java.lang.NoSuchMethodError: No static method copyInto$default([Ljava/lang/Object;[Ljava/lang/Object;IIIILjava/lang/Object;)[Ljava/lang/Object; in class Lkotlin/collections/ArraysKt; or its super classes (declaration of 'kotlin.collections.ArraysKt' appears in /data/app/com.example.debug-1/base.apk)

This is the line in question in OkHttp
IIUC, Kotlin can treat a varargs as a Kotlin Array and then call extensions functions like copyInto
We're on OkHttp 4.0.1, Kotlin 1.3.40, R8 1.5.41
Our test apk correctly contains copyInto method so I don't think it's a proguard/R8 issue:
I'm at a loss as to what to test next. I asked on OkHttp's github issuse page and they suggested I post here link
Update: still happening on OkHttp 4.1.0. Also I realized that it can't be an R8 issue since R8 doesn't remove code from test apk.

Answer 1

I had a same issue , then added the mentioning lib to my project. It solved my problem:
maven :
<!-- https://mvnrepository.com/artifact/org.jetbrains.kotlin/kotlin-stdlib -->
<dependency>
<groupId>org.jetbrains.kotlin</groupId>
<artifactId>kotlin-stdlib</artifactId>
<version>1.3.70</version>
</dependency>
or
'org.jetbrains.kotlin:kotlin-stdlib:1.3.70'

Answer 2

I got the same issue when I was using okhttp3.mockwebserver.MockWebServer with https enabled with a server certificate from okhttp-tls.
In my case, the problem was that by just importing the com.squareup.okhttp3:okhttp-tls:4.2.0 dependency, org.jetbrains.kotlin:kotlin-stdlib was being resolved to version 1.2.71.
Given the copyInto method was introduced starting kotlin 1.3 it was failing with the same error you have.
I fixed it by adding explicitly the kotlin version in my gradle.build file:
testRuntime 'org.jetbrains.kotlin:kotlin-stdlib:1.3.50'

Answer 3

I got the same issue, but I'm developing a multi-module java project. It was useful that add a dependency for kotlin-stdlib in pom.xml that belongs to this module while unit testing...
When I boot this whole project, this issue came out agnain. Finally, I find this dependency need to be in the whole project's pom.xml, I mean the pom.xml in the project's root dir.
