How can I publish jar or zip file to bintray?

[volyx]

I have tried two variants, but couldn't understand what I must write in 'publications' variables?
{code}
//publications = ["mavenJava"]

filesSpec { 
    from 'build/distributions'
    into 'build/bintray'
    include '**/*.zip'
}

{code}

File tab in bintray is empty

The Bintray Gradle Plugin DSL allows you to configure the artifacts you wish to publish to Bintray using Gradle Publications (or Gradle Configurations).
The publications or configuration should be defined as part of your gradle build script (outside of the bintray closure), but their names should be referenced by the publications / configurations lists as part of the bintray closure, so that the plugin knows which publications/configurations to use.
You can can use the filesSpec closure instead as shown in the readme file instead.
We'll try to improve the description for the publications / configurations to make them clearer.

Adding to my previous message, please note that only MavenPublication's can be used as publications for the plugin.
