Hi
p2 expects the application you are installing into to have been p2-enabled. This
means that the basic Eclipse install you have and in which you are installing
should have a p2 folder in its root. You get to that state by installing this
base with p2 itself.
To be able to install something with p2 you need to have p2 metadata for it. So
the first problem is to generate p2 metadata for the complete installation.
There are two ways to get to that:
- Use PDE Build or Tycho to build the product and get them to generate complete
metadata for the product and produce the p2 enabled product. This is the
recommended way (this is for ppl running into this post without the complete
background).
- Generate metadata on the result of your own build using the
org.eclipse.equinox.p2.publisher.InstallPublisher. This application takes as
input an eclipse install and generate p2 metadata and artifact from it. With the
repositories produced by this application you can then use the p2 director to
get the p2 enabled application.
Should you care about the p2 folder?
No. The p2 folder is not something that you have to edit. It is p2 internal
representation of what it knows about the system being managed.
Are you trying to figure this out from a selfhosted environment? The support for
running p2 in a selfhosted environment is not ideal and this may be one of the
reason.
