I haven't touched coroutines in a while. runBlocking is now showing a deprecated warning, but I can find no information about this anywhere on the internet, not even the actual documentation https://kotlin.github.io/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines/run-blocking.html. Anyone know what is up with runBlocking? What will it be in 1.4?

[octylFractal]

I've not seen a depreciation warning for it, what does the full message say?

[snowe]

message has been deleted

[octylFractal]

you imported the wrong runBlocking

[octylFractal]

it's from the old experimental coroutines package

[snowe]

Hm. Apparently I was depending on org.jetbrains.kotlinx:kotlinx-coroutines-jdk8:jar:1.3.3 and it depends on org.jetbrains.kotlinx:kotlinx-coroutines-core:jar:0.22

[snowe]

I added an explicit dependency on the correct coroutines core jar and it works now. thanks.

[snowe]

hmm. switching to that fixed the deprecation, but now I get an actual error running tests...

java.lang.NoClassDefFoundError: kotlinx/coroutines/BuildersKt

[octylFractal]

I'm surprised when you say that -jdk8 pulls in 0.22

[octylFractal]

the POM is quite clear: https://repo1.maven.org/maven2/org/jetbrains/kotlinx/kotlinx-coroutines-jdk8/1.3.3/kotlinx-coroutines-jdk8-1.3.3.pom

<dependency>
<groupId>org.jetbrains.kotlinx</groupId>
<artifactId>kotlinx-coroutines-core</artifactId>
<version>1.3.3</version>
<scope>compile</scope>
</dependency>

[snowe]

yeah idk. i ran mvn dependency:tree and that's what I got.

[snowe]

super strange.

[octylFractal]

perhaps -jdk8 is being pulled to a lower version for some reason?

[octylFractal]

that's probably the fix you'll need, is whatever fixes this dependency issue

[octylFractal]

not familiar enough with maven to tell you where to look though

[snowe]

no worries, I'll get it.

[snowe]

thanks for the help

[louiscad]

I'm curious to learn about your dependency setup

[snowe]

what do you mean?

[louiscad]

How you got to have these two dependencies in your project, I'd like to know what is the setup, and I'm also curious how it happened.

[snowe]

which two dependencies? We have a java/kotlin multimodule project (maven) with a parent bom. In a submodule I specified the jdk8 coroutines library. that was it.

[louiscad]

You're using maven and not Gradle?

[snowe]

for this project yes.

[snowe]

we’re having trouble converting it to gradle
