Migration of highly complex Eclipse platform based product build automation from Ant to Maven-based Tycho

Migrated highly complex Eclipse platform based product build automation from Ant to Maven-based Tycho.

Some of the problems included:

Company’s product highly complex tech stack required migration of its Eclipse platform based product build automation from Ant to Maven-based Tycho
Most Eclipse platform based projects were already using Tycho for some time making Company’s build automation outdated and hard to maintain
It was not known whether Tycho build automation works with CVS
Project structure used in Company’s CVS repository was not compatible with neither Maven-based Tycho nor Maven SCM plugin
Some 3rd party dependencies used in Company’s product build were not packaged for use in OSGi container

Some of the solutions applied included:

Researching and prototyping to understand how Company’s product build automation can be migrated from Ant to Tycho
Developing proof of concept using Maven SCM plugin with CVS provider to check out source from Company’s CVS repository
Developing custom Maven plugin Mojo that wraps Maven SCM plugin and allows to check out from CVS repository into Maven-compatible hierarchical directory structure
Developing custom Maven plugin Mojo that supports updating bundle and feature version identifiers incrementally
Developing specialized POM profiles – for creating P2 repo for Eclipse RAP platform build and building Company’s product using build timestamps as well as custom qualifiers
OSGifying any 3rd party depedencies not packaged for use in OSGi container using Maven ‘p2-maven-plugin’ plugin
Updating target definition and product definition files to reflect changes applied
