Nebula release and bintray plugin have version set to unspecified

This is just a repost of my question over on SO, https://stackoverflow.com/questions/51014327/nebula-release-and-bintray-plugin-have-version-set-to-unspecified

This is not the same issue that I have seen elsewhere, where the version isn’t set in the pom and file name, this is the version not being set in bintray’s ui thing. I’m pretty much gonna post word for word from my SO post for this.

Using the nebula.release and nebula.nebula-bintray-publishing plugins results in the version being set properly in the file name, but not in the file path. The error message is as below

Could not upload to 'https://api.bintray.com/content/[secure]/maven/Axon-Kotlin/unspecified/com/tylerthrailkill/axon-kotlin/0.0.2/axon-kotlin-0.0.2-sources.jar': HTTP/1.1 409 Conflict [message:Unable to upload files: An artifact with the path 'com/tylerthrailkill/axon-kotlin/0.0.2/axon-kotlin-0.0.2-sources.jar' already exists]

Using the nebula.release and nebula.nebula-bintray-publishing plugins results in the version being set properly in the file name, but not in the file path. The error message is as below.

Could not upload to ‘https://api.bintray.com/content/[secure]/maven/Axon-Kotlin/unspecified/com/tylerthrailkill/axon-kotlin/0.0.2/axon-kotlin-0.0.2-sources.jar’: HTTP/1.1 409 Conflict [message:Unable to upload files: An artifact with the path ‘com/tylerthrailkill/axon-kotlin/0.0.2/axon-kotlin-0.0.2-sources.jar’ already exists]

ignore the part about it already existing, I am just trying with the same version number over and over until the path is right.

This is what I see in bintray.

This is resulting in my bintray versions not being categorized.

Using gradle 4.8.1

build.gradle

plugins {
    id 'nebula.kotlin' version '1.2.50'
    id 'nebula.maven-publish' version '8.0.0'
    id 'nebula.info' version '3.7.1'
    id "nebula.source-jar" version "8.0.0"
    id "nebula.javadoc-jar" version "8.0.0"
    id 'nebula.nebula-bintray-publishing' version '3.5.4'
    id 'nebula.release' version '6.3.5'
}

apply from: 'publishing.gradle'

group 'com.tylerthrailkill'
// don't specify version because release plugin does

repositories {
    mavenCentral()
    mavenLocal()
}
def axonVersion = '3.2.2'

dependencies {
    compile group: "org.axonframework", name: "axon-core", version: axonVersion
    compile group: "org.axonframework", name: "axon-test", version: axonVersion
    compile group: 'org.hamcrest', name: 'hamcrest-all', version: '1.3'

    testImplementation 'org.junit.jupiter:junit-jupiter-api:5.0.3'
    testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.0.3'
    testCompile group: 'org.hamcrest', name: 'hamcrest-all', version: '1.3'
    testCompile "com.nhaarman:mockito-kotlin:1.5.0"

    testCompile "org.jetbrains.kotlin:kotlin-test:1.2.41"
    testCompile group: "org.axonframework", name: "axon-core", version: axonVersion
    testCompile group: "org.axonframework", name: "axon-test", version: axonVersion
}

test {
    useJUnitPlatform()

    // Always run tests, even when nothing changed.
    dependsOn 'cleanTest'

    // Show test results.
    testLogging {
        events "passed", "skipped", "failed"
    }
}

publishing.gradle

apply plugin: "nebula.release"
version = project.version
bintray {
    user = findProperty('bintrayUser') ?: System.getenv('BINTRAY_USER')
    key = findProperty('bintrayKey') ?: System.getenv('BINTRAY_KEY')

    pkg {
        userOrg = 'snowe'
        repo = 'maven'
        name = 'Axon-Kotlin'
        licenses = ['MIT']
        vcsUrl = 'https://github.com/snowe2010/axon-kotlin.git'
        websiteUrl = 'https://github.com/snowe2010/${project.name}'
        issueTrackerUrl = 'https://github.com/snowe2010/${project.name}/issues'
        vcsUrl = 'https://github.com/snowe2010/${project.name}.git'
        labels = ['axon', 'kotlin']
    }
}

This turned out to be a bug in the bintray plugin 1.8.3. it was fixed in 1.8.4. I am still having issues, but they are just slightly different.
