Bintray plugin doesn't seem to include AAR file: Error:Failed to resolve AAR

Question

I am trying to upload my library with following build script to Bintray. Note that it has a compile project(':oppwa.mobile-2.2.0') I have downloaded this AAR file and added as a module dependency to my library. When I run ./gradlew bintrayUpload - I get a gradle complile line: compile 'ai.devsupport:peachpay:0.0.1'

However, when I add this line to a new project, I get this error:

Error:Failed to resolve: PeachPay:oppwa.mobile-2.2.0:unspecified

My build.gradle as follows:

apply plugin: 'com.jfrog.bintray'

allprojects {
    repositories {
        jcenter()
        mavenCentral()
        maven { url "http://clojars.org/repo" }

Any help? Problem is Bintray doesn't throw any error - that creates confusion.
