Re: p2 installer provides extension points?

The installer doesn't really do anything very interesting. It really just creates a shell, prompts for install location, and then invokes IDirector.provision to perform the actual install. We never thought of the installer as the foundation for a commercial quality installer and thus didn't design much extensibility into it. It does have some minimal provisional API (package org.eclipse.equinox.internal.provisional.p2.installer), which I could imagine promoting to real API in 3.5. I suspect this still won't be sufficient for your needs and you would be better off writing your own installer that just invokes the IDirector API to perform the actual install.

Hi Pascal,

Thanks for your reply.

As far as I understood, the given installer is an example given by Eclipse
of how we can create an installer based on equinox (p2) and does not have
extension points available (right now). Is that right?

The essence of my question is because I would like to create an installer on
top of p2 and add some functionalities to it. As all eclipse-based products
are distributed over the EPL license, I would like to know if have a way to
contribute with new functionalities to it without modifying the given
example code, that is, using its available extension points.

Thanks,

Pedro Carneiro.
