[news.eclipse.technology.imp] Re: Problem installing IMP on Eclipse 3.5 
OK, thanks.  The install of the latest IMP release completed successfully.

Hi there,

[Sorry for taking a while to respond to this.]

I think you shouldn't have any problems if you install the latest
release (published a few days ago) from the update site, and select
both the IMP Metatooling and LPG Metatooling features.

That said, I was surprised to see the dependency you discovered.
(But thanks for bringing this to our attention!)

Schematically, in ASCII art:

  -----------------------------------     -------------------------------
  | IMP Metatooling feature         |     | LPG Metatooling feature     |
  |                                 |     |                             |
  |   ----------------------------  |     |   ------------------------| |
  |   | o.e.i.cheatsheets plugin |  |     |   | o.e.i.lpg.metatooling | |
  |   |  depends on:             |  |     |   |                       | |
  |   |    o.e.i.lpg.metatooling |  |     |   ------------------------- |
  |   ----------------------------  |     |                             |
  |  depends on:                    |     |  depends on:                |
  |    o.e.i.runtime                |     |    <no feature deps>        |
  -----------------------------------     -------------------------------


This obviously shouldn't be:

 - For one thing, the feature deps should abstract their plugin deps.
   [I.e., if feature F1 contains plugin P1, and feature F2 contains
   plugin P2, and P1 depends on P2, then F1 should depend on F2.]

 - Perhaps more importantly, if anything, the LPG Metatooling components
   should depend on the IMP Metatooling components, and not the other
   way around.

This will be fixed in the next release.

I'm trying to install IMP on Eclipse 3.5 GA using the Update site
http://download.eclipse.org/technology/imp/updates. I was able to install the following IMP components:

  IMP Program Analysis (Incubation)    0.1.6
  IMP Program Analysis UI (Incubation)    0.1.5
  IMP Runtime (Incubation)    0.1.99
  IMP Source Formatting Support (Incubation)    0.1.4
  LPG Generator and Templates    2.0.16
  LPG Runtime (Incubation)    2.0.16

But I was not able to install these components:

    IMP Language Meta-Tooling (Incubation)    0.1.94
    LPG Meta-Tooling (Incubation)    0.1.90

Here's the message I get when I try to install the IMP Language Meta-Tooling:

Cannot complete the install because one or more required items could not be found.

And here's the message when I try to install the LPG Meta-Tooling component:

Cannot complete the install because one or more required items could not be found.

Am I doing something wrong? Is there a way to install the components in my IDE without going through the Update manager?
