POM of kotlinx-coroutines-debug is invalid as of version 1.6.2

[GreyTeardrop]

As of version 1.6.2, the POM of kotlinx-coroutines-debug is invalid and breaks a (Maven) build for us, as it includes a dependency on kotlinx-coroutines-bom with scope runtime, so Maven tries to get a jar for kotlinx-coroutines-bom which obviously doesn't exist.

Version 1.6.3 of kotlinx-coroutines-debug is also affected.

I see that #3281 is the root cause, we'll definitely fix that, thanks!

The trick her is to prevent such situations in the future

[jesperancinha]

In the meantime, I'm adding this to all my projects where I found this problem as a workaround:

<dependency>
    <groupId>org.jetbrains.kotlinx</groupId>
    <artifactId>kotlinx-coroutines-debug</artifactId>
    <version>${kotlinx-coroutines-debug.version}</version>
    <exclusions>
        <exclusion>
            <groupId>org.jetbrains.kotlinx</groupId>
            <artifactId>kotlinx-coroutines-bom</artifactId>
        </exclusion>
    </exclusions>
</dependency>

Do you have any idea of when the new release will be out?

[qwwdfsad]

Next week hopefully

We are still experiencing this problem with Ktor 2.1.1, Could not find artifact org.jetbrains.kotlinx:kotlinx-coroutines-bom:jar:1.6.3. Could it be because some dependencies of Ktor still use 1.6.3 of coroutines? You have defined coroutines 1.6.3 in gradle/libs.versions.toml:

https://github.com/ktorio/ktor/blob/d300441cb70b6a590ebe263febc36f3fe825b4f6/gradle/libs.versions.toml#L4

While in gradle.properties you have used 1.6.4:

https://github.com/ktorio/ktor/blob/d300441cb70b6a590ebe263febc36f3fe825b4f6/gradle.properties#L34

Does adding an explicit dependency for coroutines 1.6.4 help? Also, CC @e5l.

[mikaello]

Adding

    <dependency>
      <groupId>org.jetbrains.kotlinx</groupId>
      <artifactId>kotlinx-coroutines-bom</artifactId>
      <version>1.6.4</version>
      <type>pom</type>
    </dependency>

... did not help. If no one else is getting this error, it may be something broken in our setup, it just seemed like a possible cause of the error that 1.6.3 was still mentioned as the version of coroutines in gradle/libs.versions.toml.

[hermanjakobsen]

For our projects, using

<dependency>
  <groupId>io.ktor</groupId>
  <artifactId>ktor-server-tests-jvm</artifactId>
  <version>2.0.3</version>
  <scope>test</scope>
</dependency>

with version 2.0.3 or higher results in could not find artifact org.jetbrains.kotlinx:kotlinx-coroutines-bom:jar:1.6.3. The dependency works fine with version 2.0.2.

Other ktor dependencies works fine with versions higher than 2.0.2 (e.g. ktor-server-core-jvm and ktor-server-content-negotiation-jvm).

[hermanjakobsen]

I guess this works as a workaround:
