p2 and fragments

Published by under Eclipse,IT,Java

Recently I’m getting a bit confused about p2. There is an update site created with PDE headless build. There are IUs generated for each plug-in/fragment/feature. Everything looks great so far.

Let’s assume: plug-in A and fragment B with a defined host plug-in A are sitting together on single update site. Plug-in A in reality cannot run without appropriate version of fragment B (e.g. situation similar to SWT).

My understanding of p2-power was that I wouldn’t need to create separate feature C aggregating A and B just to make fragment B be automatically installed when I request installation of plug-in A.

I spent some time on reviewing Eclipse Bugzilla and mailing lists. Interesting findings:

Any suggestions about handling such “required” fragment scenario without getting rid of autogenerated p2 repository and hand crafting p2 metadata?
