Example RCP Application

• Project types in this application• Plugins• Features• Update Site• Products

• Product come with different brandings: blue, orange, german

• Build Target:• Create ZIP distributions for branded

products

Automated Build for Eclipse/OSGi

• Several frameworks serving this task• PDE Build• Buckminster• Pluginbuilder• b3• Athena Common Build Infrastructure

• Often hard to setup, maintain and debug a working headless build• P2 makes some things better and many worse

6


Tycho

• Maven extensions for Eclipse / OSGi• Seamless build for Eclipse artifacts

• Plugins, Plugin-Tests, Features, Update Sites, Products• Manifest-first approach• POM needed for each module, but minimal one• Tight integration with Equinox / P2• Proposed as project under the Eclipse Technology project in April 2010

Packaging extensions

• Target artifact type is specified with <packaging> element in pom.xml

• Standard packaging types:• pom - jar• war - ear• ...

• Tycho adds Eclipse specific packaging types• eclipse-plugin - eclipse-test-plugin• eclipse-feature - eclipse-update-site• eclipse-application

10


Target Platform

• Set of plugins and features, against which modules/projects are built

• Computed seperately for each module• Configurable via

• System property -Dtycho.targetPlatform=<eclipsehome>

• Repositories in POM with <layout>p2</layout>

• Target Platform Definition file (.target) stored in a Maven repository

Getting started with Tycho

• Get Maven 3 Installation• Add a pom.xml to each project• Bootstrap pom.xml creation:

mvn \ org.sonatype.tycho:maven-tycho-plugin:generate-poms \ -DgroupId=com.siemens.ct.mp3m \ -Dversion=3.5.1-SNAPSHOT \ -Dtycho.targetPlatform=<path-to-eclipse>

Parent POM

• Aggregates all projects as modules• Common build settings

• Tycho plugins• Other Maven plugins• Repositories• Target platform• Target environments

• Usually in the directory „above“ the projects• This would be the workspace root in Eclipse!

Maven 3

34


Maven 3

• Complete rework of Maven 2• Current version 3.0-beta-1

• Really stable already• Mostly backward compatible• Important projects developed for Maven 3

• m2eclipse• Tycho• Maven Shell• Polyglot Maven

35


Maven Shell

• CLI interface, Wrapper for normal shell• Faster turn-around

• project information always in-memory• plugins loaded only once

36


Maven Shell - Execution Time

• Apache Commons Lang 2.5• Goals: clean package

37

mvn mvnsh


Polyglot Maven

• Multilanguage support for definition of POMs• Alternative to XML POM definition• Supported languages

• Groovy• Scala• JRuby• Clojure

• Xtext external DSL coming up

• Maven Tycho can make headless Eclipse Builds easy• Still under development

• Expect some bugs • Report them!• Rapid improvement through developers• Documentation needs to be improved

• Tycho is likely to be the next generation build framework for Eclipse!

• Don‘t fear upgrading to Maven 3
