Did anybody manage to publish a multiplatform project to Sonatype? 🤔

A POM cannot have multiple artifacts with the same type and classifier. Already have MavenArtifact fluid-stdlib-metadatajar.ascasc:null, trying to add MavenArtifact fluid-stdlib-metadatajar.ascasc:null

(same here, unanswered: https://stackoverflow.com/questions/54318156/kotlin-multiplatform-library-project-upload-issue-pom-multiple-artifacts)

configuration: https://github.com/fluidsonic/fluid-library/blob/master/sources/FluidLibraryVariantConfiguration.kt#L168

Sent a pull request that should fix your publication issue: https://github.com/fluidsonic/fluid-library/pull/1
EDIT: Probably doesn't fix the issue.

[Marc Knaup]

Thanks, but that's a Gradle plugin, not the multiplatform library I'm trying to publish 😄

[Marc Knaup]

It just uses that plugin

[Marc Knaup]

Failing lib is here:

You should still look at the generated pom xml files on your machine to see where the issue comes from

[louiscad]

null doesn't seem to be a proper version number

[Marc Knaup]

According to the error message the problem is that fluid-stdlib-metadata:jar.asc is added twice.

[Marc Knaup]

whatever that is

[louiscad]

You can see the pom xml files it in your-module/build/publications

[Marc Knaup]

it looks fine:

<project xmlns="<http://maven.apache.org/POM/4.0.0>" xsi:schemaLocation="<http://maven.apache.org/POM/4.0.0> <http://maven.apache.org/xsd/maven-4.0.0.xsd>" xmlns:xsi="<http://www.w3.org/2001/XMLSchema-instance>">

[louiscad]

What about the non metadata module?

[louiscad]

The jvm one

[Marc Knaup]

Also looks good.
And works fine for Bintray.
Just Sonatype publishing is failing

[louiscad]

Bintray is not as regarding as Bintray regarding the corectness of the publication

[louiscad]

This error still, makes me think of Java 9 jigsaw modules where you can't use the same package in different artifacts (but subpackages are fine as long as there's no classes in the same packages).

I saved a repo to my list

[addamsson]

I don't remember who was it but he clamied that it works for him on Sonatype

[addamsson]

one moment

[addamsson]

here you go: https://github.com/ToxicBakery/Arbor

[addamsson]

check it out

[Marc Knaup]

Thank's, doing that right now. No luck so far but it definitely works differently.

[addamsson]

i haven't tried it yet but i will this month

[addamsson]

i'm going to write on my blog with the results

[Marc Knaup]

wow, that required quite a lot trial & error.
Thank you for pointing me in the right direction, it finally works 🎉

I have yet to test whether the library works properly once it's finally available on Maven Central.
