Package not created on bintray

[cbeust]

Tried to upload a brand new project to bintray (without creating the package there):

───── kobalt-groovy:assemble
Directory docs/javadoc/ doesn't exist, not including it in the jar
  Created ./kobaltBuild/libs/kobalt-groovy-0.1.pom
    INC - Incremental task kobalt-groovy:assemble done running, saving checksums
Task succeeded: {TaskResult value:kobalt-groovy:assemble, success:true}
  Removing kobalt-groovy:assemble
───── kobalt-groovy:generatePom
  Created ./kobaltBuild/libs/kobalt-groovy-0.1.pom
Task succeeded: {TaskResult value:kobalt-groovy:generatePom, success:true}
  Removing kobalt-groovy:generatePom
