My project is a kotlin multi-platform one and following is the publish settings in gradle:

publishing {
    repositories {
        maven {
            url  = project.projectBintrayRepo
        }
    }

    publications {
        mavenProject(MavenPublication) {
            groupId project.groupId
            artifactId project.projectBintrayArtifactName
            version project.kyugaVersion
            withPom(pom)
        }
    }
}

Please help

1. Something in your project is trying to get a publishableFiles property from a MavenPublication. As the error indicates, no such property exists.
2. Looks like you're trying to publish to a repository that does not exist, hence the 404 Not Found. You need to publish to a repository that exists.
