| <p>The Tycho project is a proposed open source project under the <a |
| href="http://www.eclipse.org/projects/project_summary.php?projectid=technology">Technology |
| Project</a>.</p> |
| |
| <p>This proposal is in the Project Proposal Phase (as defined in the |
| Eclipse Development Process) and is written to declare its intent and |
| scope. We solicit additional participation and input from the Eclipse |
| community. Please send all feedback to the <a |
| href="http://www.eclipse.org/forums/eclipse.tycho">Tycho</a> Eclipse |
| Forum.</p> |
| |
| <h2>Background</h2> |
| |
| <p>As more Eclipse users are looking at Maven-based build solutions, |
| along with the great interest in Tycho interest we see from the Eclipse |
| community itself, we feel it's time to bring Tycho to Eclipse. The |
| majority of the Tycho user community are interested in bringing Tycho to |
| Eclipse so that's the path we are taking.</p> |
| |
| <h2>Scope</h2> |
| |
| <p>Tycho is focused on a Maven-centric, manifest-first approach to |
| building Eclipse plug-ins, features, update sites, RCP applications and |
| OSGi bundles.</p> |
| |
| <h2>Description</h2> |
| |
| <p>Tycho is a set of Maven plugins and extensions for building |
| Eclipse plugins and OSGi bundles with Maven. Eclipse plugins and OSGi |
| bundles have their own metadata for expressing dependencies, source |
| folder locations, etc. that are normally found in a Maven POM. Tycho |
| uses native metadata for Eclipse plugins and OSGi bundles and uses the |
| POM to configure and drive the build. Tycho supports bundles, fragments, |
| features, update site projects and RCP applications. Tycho also knows |
| how to run JUnit test plugins using OSGi runtime and there is also |
| support for sharing build results using Maven artifact repositories.</p> |
| |
| <p>Tycho plugins introduce new packaging types and the corresponding |
| lifecycle bindings that allow Maven to use OSGi and Eclipse metadata |
| during a Maven build. OSGi rules are used to resolve project |
| dependencies and package visibility restrictions are honoured by the |
| OSGi-aware JDT-based compiler plugin. Tycho will use OSGi metadata and |
| OSGi rules to calculate project dependencies dynamically and injects |
| them into the Maven project model at build time. Tycho supports all |
| attributes supported by the Eclipse OSGi resolver (Require-Bundle, |
| Import-Package, Eclipse-GenericRequire, etc). Tycho will use proper |
| classpath access rules during compilation. Tycho supports all project |
| types supported by PDE and will use PDE/JDT project metadata where |
| possible. One important design goal in Tycho is to make sure there is no |
| duplication of metadata between POM and OSGi metadata.</p> |

| Related Projects |
| </h2> |
| |
| <p>There are existing solutions at Eclipse in the same space at |
| Tycho. Among these solution are Buckminster, B3, PDE Build, and Athena. |
| Tycho will collaborate with these projects on P2 interoperability |
| issues, but aside from that Tycho competes with these projects.</p> |
| |
| <h2>Project Scheduling</h2> |
| |
| <p>The initial code contribution will be made when the project |
| review process is completed. We plan to release Tycho 1.0 in Q3 2010.</p> |
