6 likes2,376 views
The document introduces Tycho, a set of Maven plugins designed for building, testing, and releasing Eclipse/OSGi artifacts. It details Tycho's capabilities, its integration with Maven and p2 for dependency resolution, and includes a real-life demo and pointers for further exploration. Tycho simplifies the building of OSGi bundles and Eclipse plugins, requiring minimal Maven background to use.
Tycho - Building plug-ins with Maven
- 1. Tycho Building Eclipse plug-ins with Maven Pascal Rapicault, Sonatype Tycho enthusiast 1 Transforming Software Development
- 2. Goal of this session • Introduce Tycho • Show Tycho capabilities and simplicity • Provide pointers for further exploration 2 Transforming Software Development
- 3. Content of this session • What is Tycho? • Real life build demo • Relationship with other technologies • Step-by-step build • Q&A 3 Transforming Software Development
- 4. What is Tycho? • A way to build, test and release Eclipse/OSGi artifacts with Maven • Tycho feature list: • Build OSGi bundles / Eclipse plugins • Execute tests within the OSGi runtime • Build Eclipse Features • Build p2 repositories • RCP applications a.k.a. Products • ... • Integrates with the rest of the Maven ecosystem 4 Transforming Software Development
- 5. Facts about Tycho • Where is tycho hosted? • Sonatype donated Tycho to Eclipse Foundation. • Tycho origin • Initial work started by Tom Huybrechts at Agfa • Current contributors • SAP, Sonatype, Intallio • Who is using it? • Numerous companies and open source projects 5 Transforming Software Development
- 6. Real life demo 6 Transforming Software Development
- 7. Relationship with Maven • What is Maven? A build system • Tycho is a set of Maven plugins • How is it different from other Maven plugins? • It reuses the PDE metadata to configure the build • It alters the standard Maven resolution logic to support OSGi dependencies (manifest.mf, feature.xml, etc.) • It adds the ability to Maven to read p2 repository 7 Transforming Software Development
- 8. Relationship with p2 • What is p2? An OSGi-based provisioning system for OSGi. • p2 is present throughout Tycho • As input, tycho reads and downloads dependencies from p2 repositories. • As output, tycho produces p2 repositories • Internally, tycho embeds parts of p2 in order to perform the dependency resolution Maven + p2 = Tycho :-) 8 Transforming Software Development
- 9. Relationship with PDE • What is PDE? Set of eclipse plugins to build Eclipse plugins. • PDE UI • Reuses most files promoted by PDE such as MANIFEST.MF, build.properties, feature.xml, site.xml, .product • Reuses PDE UI infrastructure like classpath management, launching capabilities, editors for OSGi manifest, features, for IDE integration • PDE Build • "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 Transforming Software Development
- 10. Step-by-step build 10 Transforming Software Development
- 11. Closing remarks • Tycho does not require a lot of Maven background • Makes building and testing OSGi bundles / Eclipse plugins easy • Go try it! 11 Transforming Software Development
