It is a fork of JeroenMols's GitAsMaven to support Bitbucket Cloud OAuth 2.0 (Because the Bitbucket Cloud v1 API are deprecated).

GitAsMaven

Gradle script to use Git as a private Maven repository.

Currently only BitBucket is supported, as the offer free private repositories. GitHub support easily be added in a similar script.

Prerequisites

1. BitBucket repository with a releases as its main branch, as described in this blogpost.
2. Add an OAuth consumers with bitbucket settings and grant permissions
3. Update Gradle version to nightly version

./gradlew wrapper --gradle-version=4.10-20180730054456+0000

Usage

Add following script to the top of the build.gradle file in your library and java project folder

task configured {
  project.ext.ACCESS_TOKEN = getAccessToken()
}

import groovy.json.JsonSlurper

String getAccessToken() {
  def body = 'grant_type=client_credentials'
  def http = new URL('https://bitbucket.org/site/oauth2/access_token').openConnection() as HttpURLConnection
  def s = project.KEY + ':' + project.SECRET
  http.setRequestProperty ("Authorization", 'Basic ' + s.bytes.encodeBase64().toString());
  http.setRequestMethod("POST");
  http.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
  http.setUseCaches(false);
  http.setDoInput(true);
  http.setDoOutput(true);
  http.outputStream.write(body.getBytes("UTF-8"))
  http.connect()

  def response = [:]

  if (http.responseCode == 200) {
    response = new JsonSlurper().parseText(http.inputStream.getText('UTF-8'))
    return response.access_token
  } else {
    response = new JsonSlurper().parseText(http.errorStream.getText('UTF-8'))
    println "response: ${response}"
    assert response.access_token != null
  }
}

1. Add the following plugin to the top of the build.gradle file in your library folder

apply from: 'https://raw.githubusercontent.com/zhouzm/GitAsMaven/master/publish-bitbucket.gradle'

2. Create a gradle.properties file in the root of your project with the following parameters:

KEY=<bitbucket_consumer_key>
SECRET=<bitbucket_consumer_secret>
USERNAME=x-token-auth

ARTIFACT_VERSION=<version_here>
ARTIFACT_NAME=<libraryname_here>
ARTIFACT_PACKAGE=<packagename_here>
ARTIFACT_PACKAGING=jar //You could also use aar

COMPANY=<bitbucket_team/company_here> //Simply your username if you're not part of a team
REPOSITORY_NAME=<bitbucket_reponame_here>

Note: Do not check this file into version control!

3. Run the following command to upload a version to your Maven repository.

./gradlew uploadArchives

  jcenter()
  mavenCentral()
  maven {
    url 'https://api.bitbucket.org/2.0/repositories/'+COMPANY+'/maven_repository/src/releases'
    credentials(HttpHeaderCredentials) {
      name = "Authorization"
      value = 'Bearer ' + project.ACCESS_TOKEN
    }
    authentication {
      header(HttpHeaderAuthentication)
    }
