5. My Role
• Engineering Tools
• We help, when and where we can
• Build, Bake, Deploy, Monkey
• Lead on internal Gradle and Ant builds

6. Environments
All of Maven Central
Publish to Sonatype
Maven On The Outside
Done in the public
Setup everything
No Maven Central
Publish to Artifactory
Ivy On The Inside
Legacy Conventions
Minimal Setup

7. Phase 0: Use Gradle

8. Phase 1: Naive Approach
• Copyable build
• build.gradle
• gradle/conventions.gradle
• gradle/maven.gradle
• gradle/netflix-oss.gradle
• Decent examples online
http://jedicoder.blogspot.com/2011/11/automated-gradle-project-deployment-to.html

9. ext.releaseVersion = '1.1.3' // TEMPLATE
ext.githubName = project.name // TEMPLATE
apply from: file('gradle/convention.gradle')
apply from: file('gradle/maven.gradle')
apply from: file('gradle/check.gradle')
group = 'com.netflix'
repositories {
mavenCentral()
}
dependencies { // TEMPLATE
compile 'javax.ws.rs:jsr311-api:1.1.1'
compile 'com.sun.jersey:jersey-core:1.11'
testCompile 'org.testng:testng:6.1.1'
testCompile 'org.mockito:mockito-core:1.8.5'
}
build.gradle

10. ext.performingRelease = project.hasProperty('release') &&
Boolean.parseBoolean(project.release)
def versionPostfix = performingRelease?'':'-SNAPSHOT'
version = "${releaseVersion}${versionPostfix}"
status = performingRelease?'release':'snapshot'
apply plugin: 'java' // Plugin as major conventions
sourceCompatibility = 1.6
// GRADLE-2087 workaround, perform after java plugin
status = rootProject.status
task sourcesJar(type: Jar, dependsOn:classes) {
classifier = 'sources'
from sourceSets.main.allSource
}
task javadocJar(type: Jar, dependsOn:javadoc) {
classifier = 'javadoc'
from javadoc.destinationDir
}
convention.gradle

11. apply plugin: 'maven'
apply plugin: 'signing'
signing { sign configurations.archives}
task uploadMavenCentral(type:Upload) {
configuration = configurations.archives
dependsOn signArchives
doFirst.repositories.mavenDeployer {
beforeDeployment { signing.signPom(it) }
repository(url: 'http://oss.sonatype.org/services/local/
staging/deploy/maven2/') {
authentication(userName: rroject.sonatypeUsername, password:
project.sonatypePassword)
}
pom.project {
url "https://github.com/Netflix/${project.githubName}"
...
}
}
}
maven.gradle

12. apply from: 'http://artifacts.netflix.com/gradle-netflix-local/
artifactory.gradle'
netflix-oss.gradle

13. gradle-template
• Be as visible as possible
• Meant to be synced with (#git #ftw)
• Templates for multiple-module and single-module
projects
• Used by other companies
• https://github.com/Netflix/gradle-template

14. Phase 2: Full Build
• Release plugin [gradle-release]
• Publish snapshots, candidates and releases
• Simpler signing in Jenkins
• License and Copyright Headers [license-gradle-plugin]
• Any plugins in Bintray
• Publishing Javadoc
• More code quality checks

15. Continuous Integration
• Jenkins Internally
• Performs releases
• Has Keys
• Access to AWS
• CloudBees DEV@CLOUD Externally
• Builds Pull Requests
• Shows Code Quality Metrics

16. Problem Areas
• Java plugin required for conf2scope mappings to work
• Java plugin resets status [GRADLE-2087]
• Parent poms caused problems, but aren’t needed
• Sonatype username/password
• Signing keys needed locally with special properties
• Not all plugins were available

17. Future
• Roll features into plugins
• Merge with internal build
• Hire more engineers to work on Gradle
