Before you publish to Bintray you must have a stable build of your code. The hierarchy on Bintray is the following: User --> Repo --> package --> version --> artifact means that the Repo should be above the package by that hierarchy.

The following lines in your gradle.build are probably the main cause for the error:

pkg {
    repo = 'maven'
    name = 'helloaar.example.com.mylittlelibrary'
}

The hierarchy is wrong.

When using maven you should check that you comply with the maven convention, else the Maven Build can not succeed. Explanation for Maven Repositories on Bintray.

The error you had:

HTTP/1.1 404 Not Found [message:Repo 'maven' was not found] 

Means that you do not have a Repository on Bintray calls maven. All the packages versions and files should be under the Bintray Repository you have created.

For more details or support issues you can use the Bintray support team which is available for all Bintray users and can help you with any problem related to any JFrog platform services such as Bintray, Artifactory, Mission control & Xray.
