Building Eclipse Plugins with Tycho
- 1. Building Eclipse plugins and RCP applications with Tycho, Nexus & HudsonIgor Fedorenko, SonatypePascal Rapicault, SonatypeJan Sievers, SAP
- 2. Contents of this sessionPart I: Introduction to Maven TychoWhat is Tycho?What can it do?How does it relate to Maven, p2, PDE?Who is using it?Real-life Build DemoQ&APart II: Hands-on exercises. Learn how to buildPlugins/OSGi bundlesTestsFeaturesp2 repositoriesRCP applications/products
- 3. What is Tycho?A way to build, test, release and publishEclipse/OSGi artifacts with mavenIt can buildEclipse Plugins/OSGi bundlesExecute tests within the OSGi runtimeFeaturesp2 repositoriesRCP applications a.k.a. Products
- 4. Who is working on tycho?Tycho started a couple of years ago from the need to have the ability to build eclipse plugins using MavenThe initial work has been started by Tom HuybrechtsSonatype joined the forces shortly after thatNowadays, the main contributors are SAP, Sonatype and Intalio
- 5. Who is using it?Tycho is used in production by IntalioSAPSonatypeOpen source projects of different size and complexityEGitEclipse Memory AnalyzerRT JettyEquinox p2TigerstripeJBoss Tools
- 6. How does it relate to maven?Tycho is a set of maven 3 plugins which hooks into the build lifecycle at a low levelAs such, it opens up eclipse/OSGi builds to the rich Maven ecosystem of plugins for code generators, quality analysis tools, code coverage, etc. How is it different from other maven plugins?It introduces support for resolving dependencies against p2 repositoriesIt resolves dependencies based on MANIFEST.MF/feature.xml etc. and tries to reuse other PDE metadata like build.properties („MANIFEST-first“ as opposed to „POM-first“)
- 7. How does it relate to p2?Tycho produces p2 repositories as part of a buildTycho downloads the dependencies of the entities being built from p2 repositories. By default, Tycho does not resolve its dependencies from Maven repositories because the Maven dependency and repository models can not accommodate the expression of OSGi dependencies like Import-PackageTycho embeds parts of p2 in order to perform the dependency resolution and a few other key operations like publishing
- 8. How does it relate to PDE?Tycho reuses some of the files that are being used by PDE Build such as MANIFEST.MF, build.properties, feature.xml, site.xml, .product where it makes senseThis allows to reuse PDE UI infrastructure like classpath management, launching capabilities, editors for OSGi manifest, features, product files, target platforms etc.Tycho being a headless build mechanism, it "competes" with PDE build only in the sense that it provides an alternative way to do a headless build of plugins and other eclipse artifacts
- 9. Where is Tycho?Tycho is an open source project run by SonatypeIt has recently been given to the Eclipse Foundation and is currently incubatingWe are in the process of contributing the code to Eclipse Foundation but it‘s not done yet. Getting Tycho and its dependencies through Eclipse legal process is a lot of workProject homepage http://eclipse.org/tychoCurrently the codebase is still on githubUsers and development mailing lists:tycho-users@lists.sonatype.comBugs filed at https://issues.sonatype.org/browse/TYCHO
