Re: [tycho-user] Preferred way to offer zipped, standalone update sites?

[Jens Reimann <jens.reimann@xxxxxxxxxxxxxxx>]

Hi,

first of all I have to say that I am the author of what I am suggest
next ;-)

You could use Package Drone [1], which allows you to host e.g. P2
repositories. You can upload a full P2 repository zip (manually or using
mvn deploy) and consume it  as P2 repository. You can upload multiple P2
Zips into one "channel". Each channel will be rendered as a P2
repository, so you can combine multiple P2 repository. Although this is
not a composite repository, from a technical point of view. So the
amount of data you upload is under you control.

For the Maven Tycho build, or Eclipse PDE, you can then reference the
repository over HTTP.

If you need a bit of help, just let me know.
