Missing Requirement for Teneo when Creating RAP .target File [message #1744965]

I'd appreciate some help with my attempt to get started with RAP. I am trying to define a .target platform file that includes EMF, Teneo, and Hibernate. I am getting the following error (seems to be the root among a related set of errors):

"Missing requirement: EMF Teneo 2.1.0v2016... requires 'bundle org.eclipse.emf.common [2.7.0,3.0.0)' but it could not be found.

I could not find an up-to-date update site for EMF, so I ended up downloading the latest, unzipping it, and having my new .target file access it as a directory (which it seems to be seeing OK). That directory includes the org.eclipse.emf.common (2.12.0v20160420-0247). So it's unclear to me why Teneo says it can't find the dependency it needs.

Here is the current state of my .target file [NOTE: In the XML below, I had to eliminate all "http" due to the first-time poster forum filter, so I changed them all to "hllp"]:

</target>

Anyone have any suggestions as to what I'm doing wrong?

Thanks,

If the EMF plugin is available, perhaps it's dependencies are not.
After you've started the application, type "ss" in to the console to list the current bundles
If you see the bundle there and it's not ACTIVE, try and start it with "start <bundle id>"
That might give you more information as to why it's failing to start.

Thanks for your suggestion. I did manage to sort this out late yesterday (at least I think I did... for now).

First, I found the EMF plugins available from the Neon modeling site.

Then after much struggle I found a forum post somewhere that suggested unchecking the "Include required software" box on the "Add Content" wizard. That seemed to do the trick, as I stopped getting a zillion different and constantly changing failed dependency errors.

My remaining concern is that it will turn out that I did, in fact, need some of those required software packages after all, and I'll only find out by suffering through another blizzard of dependency bugs.

But I got my initial demo running, so that's progress.
