Multiple artifacts with the identical extension and classifier

[langsmith]

My work is happening at mapbox/mapbox-plugins-android#961 as I try to transition https://github.com/mapbox/mapbox-plugins-android to Bintray publishing with this plugin.

I'm trying to publish various modules as separate library
packages to the same Bintray account. For example, https://bintray.com/mapbox/mapbox/mapbox-android-plugin-building-v8.

For example:

• https://github.com/mapbox/mapbox-plugins-android/blob/ls-moving-release-process-to-bintray/plugin-building/gradle.properties
• https://github.com/mapbox/mapbox-plugins-android/blob/ls-moving-release-process-to-bintray/plugin-localization/gradle.properties
• https://github.com/mapbox/mapbox-plugins-android/blob/ls-moving-release-process-to-bintray/plugin-scalebar/gradle.properties

make build-release works fine for building all of the plugins: https://github.com/mapbox/mapbox-plugins-android/blob/ls-moving-release-process-to-bintray/Makefile#L19

But I'm getting the following error, when I run make publish (https://github.com/mapbox/mapbox-plugins-android/blob/ls-moving-release-process-to-bintray/Makefile#L27) :

Execution failed for task ':plugin-annotation:publishMapboxPluginPublicationPublicationToMavenLocal'.
> Failed to publish publication 'MapboxPluginPublication' to repository 'mavenLocal'
   > Invalid publication 'MapboxPluginPublication': multiple artifacts with the identical extension and classifier ('jar', 'sources').

At one point, my pr was set up in a certain way to create the package page on Bintray for the various plugins that I'm trying to publish.

• https://bintray.com/mapbox/mapbox/mapbox-android-plugin-scalebar-v8
• https://bintray.com/mapbox/mapbox/mapbox-android-plugin-building-v8
• etc.

However, when you click on a specific release, it doesn't have any files in it:

• https://bintray.com/mapbox/mapbox/mapbox-android-plugin-scalebar-v8/0.2.0-SNAPSHOT#
• etc.

I tried searching for multiple artifacts with the identical extension and classifier on Google, but haven't found anything very useful.

Do I need multiple MavenPublications rather than just one in gradle/gradle-bintray.gradle?

https://github.com/bintray/gradle-bintray-plugin/issues?utf8=%E2%9C%93&q=is%3Aissue+is%3Aopen+multiple didn't show any tickets that were about my current questions and issues.

Anyone able to provide any advice? @eyalbe4?

When I try to publish a specific plugin, such as make publish-building, I get the same error:

@langsmith The same error occur when I set the version value of kotlinStdLib and kotlin to 1.4.30,then I revert them to 1.4.21 it will work.
