...with Maven


Tycho and Maven
 Tycho provides a maven build extension and several
maven build plug-ins
 Maven drives the build process using the project object
model (pom.xml)
 Tycho can be combined with other Maven plug-ins
 QA tools: FindBugs, Checkstyle, PMD, ...
 Code generators
 ...
 Tycho integrates with Maven
 Follow conventions for build output folder
 Inject OSGi dependencies into Maven dependency model
 Inject source folders and compile class-path

Tycho and PDE
 Tycho re-uses PDE metadata files
 OSGi bundle manifest (META-INF/MANIFEST.MF)
 build.properties
 feature.xml
 site.xml/category.xml
 *.product files
 *.target files
 You can continue using PDE UI tools


Tycho and p2
 Tycho is a p2 artifact/metadata consumer and
producer
 Resolves dependencies against p2 repositories
 Produces p2 repositories
 Think of Tycho as a „Maven build frontend
with a p2 repository backend“
