Publish android library to jcenter: gradle bintray

Question

I'm trying to publish an Android library to jcenter. I've followed https://github.com/danielemaddaluno/gradle-jcenter-publish tutorial. Everything works fine until I try to execute

gradle bintrayUpload

When I do so I get a BUILD FAILED. When I look into the errors I see

package com.android.volley does not exist

Therefore the libraries that I have included as a gradle dependency are not being found

dependencies {
     compile 'com.mcxiaoke.volley:library:1.+' (...)
}

The same happends with other libraries included.

How can I fix this problem?

I Attach the module build.gradle

apply plugin: 'com.android.library'
apply plugin: 'com.github.dcendents.android-maven'
apply plugin: "com.jfrog.bintray"

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {

//                close = '1' //Optional property. By default the staging repository is closed and artifacts are released to Maven Central. You can optionally turn this behaviour off (by puting 0 as value) and release the version manually.
//            }
        }
    }
}

and the project build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.2'
        classpath 'com.github.dcendents:android-maven-plugin:1.2'
        classpath "com.jfrog.bintray.gradle:gradle-bintray-plugin:1.1"

    }
}

allprojects {
    repositories {
        jcenter()
    }
}

Answer 1

The library is in maven repository, so you need to declare the maven central repository. Add it in your project build.gradle file like this:

buildscript {
    repositories {
        mavenCentral()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.2'
        classpath 'com.github.dcendents:android-maven-plugin:1.2'
        classpath "com.jfrog.bintray.gradle:gradle-bintray-plugin:1.1"

    }
}

Answer 2

Please refer to the following:

  user = properties.getProperty("bintray.user")
  key = properties.getProperty("bintray.apikey")

At this point, you need in your local. Join in the properties files,

Bintray. User = XXX
Bintray apikey = XXX
