Re: [platform-ui-dev] New Platform UI contribution guide
It sounds like everything you described could be resolved very easily, mostly with minor edits to the install steps on the wiki. I'll add the information about where to find the launcher. Let's not abandon the new install steps before making at least an effort to address your problems.

I'd guess that your empty workspace is due to whatever p2 error you hit during the install. Once we understand what happened to you, we can add a troubleshooting section to help people recover if they have server connection issues during the install.

If you use help > run setup tasks, does it fix itself?

You'll also get an empty workspace if you forgot to select any projects in the project selection page. Try to reselect them from import > projects from Oomph.

Oomph doesn't support this right now. You can add the update site for the nightly or integration build post-install and it should update itself to that build.

Oomph uses a global p2 cache, so it's easy to experiment or fix things. If you mess up your install, delete it and rerun Oomph. The next install will get all of the plugins from the cache rather than re-downloading them. Just rerun the Oomph installer and point it somewhere else. The next run should be really fast.

There is no working oomph configuration for SWT. There are some folks working on setting it up right now, but the one there doesn't work. All the other platform projects work, though. I tested them just now.

I'll add a note to the wiki warning against selecting the SWT project.

Hi,
 
this is follow up on my Oomph experience report.
 
So now the installer finished to clone git repos but failed to perform some obscure p2 tasks because it could not find something I don't really care about. A typical p2 experience, nothing special for Oomph. Probably my problem is that I wanted Oomph to configure not only Platform UI but also EGit/JDT/Runtime/SWT etc. Someone from them seem to have broken Oomph setup.
 
Anyway, I have now empty Eclipse workspace with few empty "Platform UI ..." working sets and no idea how to start the Eclipse once I close it - the installer have not added any shortcut neither to the desctop nor to the start menu (I'm on KDE4 / RHEL7). So if I would close Eclipse instance started by the installer I would have no idea how to start Eclipse again. I know the installer cloned git repo, but there are no signs of it in the original Eclipse perspective itself. I know I can open "Gir Repositories" view and import the projects manually but a new contributor would have no clue what to do next (it it manages to start Eclipse second time at all!).
 
My list of show stopper problems contains now 3 items:
1) No idea how to told Oompf to use a specific nightly build for platform.
2) No idea how to start the "generated" Eclipse (OK, I can cheat and check About->Installation Details->Configuration) but a new contributor will most likely fail here.
3) For whatever reasons the projects were not imported into workspace from cloned repositories. A showstopper for a new contributors.
 
Given that I failed to use Oomph and I think I'm more experienced than a "new contributor with a small patch", can we please restore the old (manual) steps in the Wiki? Let the Oomph be there, but give disabled people like me a chance to manually install/configure all the bits.
 
P.S.
Here is the last piece of Oomph output.

Betreff: [platform-ui-dev] New Platform UI contribution guide
I've updated the instructions for contributing to platform UI to describe the steps for installing via Oomph:
 
https://wiki.eclipse.org/Platform_UI/How_to_Contribute
 
I would appreciate feedback on the guide and the setup process itself.
 
There's still some things I'm aware of that I'd still like to fix:
- The oomph install is pulling in mylyn.
- It isn't setting up an API baseline automatically, so I've left the manual steps on the wiki.
- I've uploaded an oomph configuration to the ui git repository, but the main oomph repository isn't linking to ours yet.
 
The old manual installation steps should still work, but I've removed them from the wiki to avoid confusion.
