Lessons Learned

•p2 API and documentation needs work

–Great docs for high level, concepts are clear

–Low level is difficult to understand relationships of objects

•Automate everything from checkin to publish!

•Use Tycho to Build

•Use Replication for your p2 Repositories

•Mirror external p2 repository internally

•Monitor your dependencies

•Give friendly error messages when dependencies are not available
