Publishing Android library to bintray maven produces 2 separate artifacts

I'm trying to publish my android library using bintray, but I end up with two separate artifacts in bintray maven stringx and stringx-android-sdk: https://dl.bintray.com/klimaszewski/stringx/io/stringx/ where sources and all the stuff is placed here: https://dl.bintray.com/klimaszewski/stringx/io/stringx/stringx/1.0.2/

and POM file is placed in correct artifact: https://dl.bintray.com/klimaszewski/stringx/io/stringx/stringx-android-sdk/1.0.2/

My bintray repo is: stringx and library name: stringx-android-sdk

Bacause of that library cannot be resolved in my projects. What's wrong here? build.gradle

buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }

    dependencies {
        classpath 'com.github.dcendents:android-maven-gradle-plugin:2.0'
        classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.7.3'
    }
}
apply plugin: 'com.android.library'
apply plugin: 'com.github.dcendents.android-maven'

    }
    println "Version code: " + versionCode
    return versionCode

Android module name has to match bintray package, 'stringx-android-sdk' in my case.

So I had to change module in settings.gradle

include ':stringx-android-sdk'
project(":stringx-android-sdk").projectDir = file("../../stringx")
