Probably dumb question: How do I determine p2 url for plugin from marketplace? [message #1808707]

I'm using 2019-06, and I'm starting to experiment with building an Oomph profile for my current configuration. I'm following the instructions at https://wiki.eclipse.org/Eclipse_Oomph_Authoring .

The section on installing plugins has this statement:

3. in the Properties of the Repository set the URL to a valid p2 repo (e.g. http://update.eclemma.org)

This seems trivial, but how exactly do I determine the p2 URL for any particular plugin? In my setup, I'm going to be installing some plugins from the predefined update sites (Docker tooling, for instance), some third-party plugins (Spring IDE, Groovy, MoreUnit, and a couple of others). I'm installing most of the third-party plugins from the Marketplace. For any particular marketplace plugin, how do I determine what the p2 repository URL is?

I know of no trivially easy way, but this does work:

1) Open the marketplace solution page in your browser, e.g., https://marketplace.eclipse.org/content/cdo-model-repository
2) Hover the "Install" button and note the URL, e.g., http://marketplace.eclipse.org/marketplace-client-intro?mpc_install=573
3) Change the browser address to http://marketplace.eclipse.org/node/[mpc_install]/api/p and change [mpc_install] to the number from at the end of 2), e.g., http://marketplace.eclipse.org/node/573/api/p
4) In the resulting XML page search for the <updateurl> element. It contains the address of the p2 repository.

Note that the <iu> elements contain the feature names in that p2 repository, but it appears that you need to suffix them with ".feature.group" if you want to use them in p2 Director requirements.

FYI, I'm working on a drag-and-drop solution to automate the creation of a p2 task (and/or to update a p2 task) simply by dragging the same install URL into the setup editor. It's mostly working already but Git/Gerrit is down again...

Note that drag and drop now works. I.e., you can drag a URL such as https://marketplace.eclipse.org/content/viplugin and drop it into a setup editor. The URL "induces" a resource with a Macro containing a p2 task with the appropriate update sites and IUs...
