Can you share how exactly are you resolving the dependency tree? Normally, Gradle always uses .module metadata, so it is not clear to me how you are hitting these issues in pom files.

I do see that between 1.5.0-alpha06 and 1.5.0-beta01 we regressed and moved from:

    <dependency>
      <groupId>org.jetbrains.kotlin</groupId>
      <artifactId>kotlin-stdlib</artifactId>
      <version>1.9.24</version>
      <scope>compile</scope>
    </dependency>

to

    <dependency>
      <groupId>org.jetbrains.kotlin</groupId>
      <artifactId>kotlin-stdlib</artifactId>
      <scope>compile</scope>
      <version>unspecified</version>
    </dependency>

For Googlers, 1.5.0-alpha06 was from ab/12619857 (2024-11-06) and 1.5.0-beta01 was from ab/12750671 (2024-12-04).

I bisected this down by looking at our builds androidx_snapshot repository and found

12750671 broken
12748222 broken
12695124 broken
12693463 broken
12692676 broken
12691948 broken
12691696 working
12690853 working
12689465 working
12686901 working
12684352 working
12675082 working
12660485 working
12619857 working 

That means we regressed with http://ab/12691696:12691948 which means https://r.android.com/q/topic:%22revert-3363920-revert-3303562-Kotlin+2.1.0-Beta2-TQMUQQULEJ-ZTHZKHAUFM%22

where we upgraded KGP from 2.0.10 to 2.1.0-RC

If I look at the latest build the pom is back to spec

  <dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>androidx.collection</groupId>
        <artifactId>collection-ktx</artifactId>
        <version>1.5.0-SNAPSHOT</version>
      </dependency>
      <dependency>
        <groupId>org.jetbrains.kotlin</groupId>
        <artifactId>kotlin-stdlib</artifactId>
        <version>1.9.24</version>
      </dependency>
    </dependencies>
  </dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>androidx.annotation</groupId>
      <artifactId>annotation-linuxx64</artifactId>
      <version>1.9.1</version>
      <scope>compile</scope>
    </dependency>
    <dependency>
      <groupId>org.jetbrains.kotlin</groupId>
      <artifactId>kotlin-stdlib</artifactId>
      <scope>compile</scope>
    </dependency>
  </dependencies>
</project>

It got fixed http://ab/12985034:12984869 which is https://r.android.com/q/topic:%22kotlin-2.1.10%22 which is the upgrade from KGP 2.1.0 to 2.1.10, so it must have been a bug in KGP that got fixed. and I was able to find it https://youtrack.jetbrains.com/issue/KT-73728/generatePomFileForMavenPublication-creates-pom-with-dependencies-with-unspecified-version

So we need to re-release collection library from androidx-main that has the newer KGP.

I'll bump the version of collection to 1.5.0-rc01 (https://r.android.com/3502518) and schedule a release

Thanks for the report. One thing to note, depending how custom is your pom downloader, you will need to make sure you support entries without any version, as it gets resolved through the <dependencyManagement>

    <dependency>
      <groupId>org.jetbrains.kotlin</groupId>
      <artifactId>kotlin-stdlib</artifactId>
      <scope>compile</scope>
    </dependency>

The plan for this is to release collection 1.5.0 (stable) on March 12, then make sure that compose 1.8.0-RC* moves to using that version.

Over to juanrdz@ to make sure Compose 1.8.0-* ship with the fixed collection dependency.
