Publish to JCenter

[daspilker]

The Gradle JPI plugin depends on localizer. Gradle plugins published through the Gradle Plugin Portal must should/must have their dependencies available on JCenter. The latest version on JCenter is 1.19, but I need 1.20 or later to get the JavaDoc fixes for Java 8.

Using dependencies outside of JCenter forces a verbose Gradle build file syntax:

buildscript {
    repositories {
        jcenter()
        maven {
            url('https://repo.jenkins-ci.org/releases/')
        }
    }
    dependencies {
        classpath 'org.jenkins-ci.tools:gradle-jpi-plugin:0.18.1'
    }
}

apply plugin: 'org.jenkins-ci.jpi'

instead of just

plugins {
    id 'org.jenkins-ci.jpi' version '0.18.1'
}

In order to publish to JCenter, the artifacts must be upload to Bintray from where they can be promoted to JCenter, see https://bintray.com/docs/usermanual/uploads/uploads_promotingyourmaterial.html.
