Bintray upload throws: could not get unknown property 'conf' error on Kotlin multiplatform projects

[warnyul]

I have the following configuration on my multiplatform projects (android, common, js, native)

apply plugin: 'com.jfrog.bintray'

bintray {
    user = System.getenv('BINTRAY_USER')
    key = System.getenv('BINTRAY_API_KEY')
    override = true // for multi-platform Kotlin/Native publishing
    publications = ['prefessor']
    dryRun = false
    publish = false

    pkg {
        userOrg = 'wupdigital'
        repo = 'wup-digital-maven'
        name = project.name
        licenses = ['Apache-2.0']
        vcsUrl = 'https://github.com/wupdigital/prefessor'
        websiteUrl = 'https://github.com/wupdigital/prefessor'
        issueTrackerUrl = 'https://github.com/wupdigital/prefessor/issues'
        githubRepo = 'wupdigital/prefessor'
        githubReleaseNotesFile = 'CHANGELOG.md'
        labels = [
                'Some tags'
        ]

        version {
            name = project.version
            vcsTag = project.version
            released = new Date()
        }
    }
}

// This is required for K/N publishing
bintrayUpload.dependsOn publishToMavenLocal

// This is for easier debugging of bintray uploading problems
bintrayUpload.doFirst {
    publications = project.publishing.publications.findAll { !it.name.contains('-test') }.collect {
        println("Uploading artifact '$it.groupId:$it.artifactId:$it.version' from publication '$it.name'")
        it
    }
}

bintrayUpload.enabled = isRelease()

When I run bintray upload, I get following error:

Execution failed for task ':prefessor-common:bintrayUpload'.
> Could not get unknown property 'conf' for task ':prefessor-common:bintrayUpload' of type com.jfrog.bintray.gradle.tasks.BintrayUploadTask.

Workaround:

publications = project.publishing.publications.findAll { !it.name.contains('-test') }.collect {
        println("Uploading artifact '$it.groupId:$it.artifactId:$it.version' from publication '$it.name'")
        it.name // << WORKAROUND IS HERE
    }

[ilmat192]

It looks like #228 can fix it.

[warnyul]

Probably, it fix it, however there are two typo. See #257

[jershell]

When will you fix the bug? PR waiting more time that 1 year

[dotCipher]

If this is merged, can we cut a bugfix release with it?

[neworld]

This issue is blocking me as well. The workaround is not working using kotlin-dsl.

[Him188]

Use plugin version 1.8.4-jetbrains-3

[asarazan]

I don't see that plugin version anywhere. Can you give more explanation how to use it?

Also to the Bintray team, what's the hold-up on publishing the merged fix for such an obvious typo in your code?

You may need 'kotlin-eap' repository? I'm not sure. You may get help from my project here, see 'build.gradle.kts'

[asarazan]

Ah close actually. Just tracked it down in maven(url="https://dl.bintray.com/jetbrains/kotlin-native-dependencies")

[asarazan]

Still radio silence from Jfrog. Guess it's back to filing jira tickets on Sonatype.

[martinbonnin]

For what it's worth, you can upload to bintray without the bintray plugin, just using the maven-publish plugin. It's working well with multiplatform artifacts and is bundled inside Gradle. For an exemple, you can check https://github.com/paug/openfeedback-android-sdk/blob/master/build.gradle.kts#L86

[eyalbe4]

Apologies for not being able to attend to this sooner!
Version 1.8.5 with #257 is now released.

[asarazan]

Thank you, much appreciated!
