How to completely disable Oomph in Eclipse?

Question

For a long time it was annoying in Eclipse to switch workspaces and also to lose (not permanently of course) carefully crafted settings like colors, styles, etc. And it was again annoying to recreate these settings from scratch (thus creating a new workspace was as rare as possible). And I was extremely happy to see someone decided to do something about it, so we get Oomph. But longer I use it, more I think that the solution is actually worse than the original problem. First of all, it just doesn't work as one would expect. So I said to myself: "OK, give it a time, be patient, maybe you just don't know how to properly use it" (and probably I still can't). But after few years I end up with dozens of different versions of Eclipse installed around, because of this Oomph thing. And now (Oxygen.3a) it is tied to Eclipse and apparently I can't remove it.

But why would I do that? Because I'm loosing control over the settings! It changes syntax color at its whim, ignores indeterminably part of these settings (Java Editor Syntax Color) and other settings too. Oh, I tried to disable recording or startup task, but to no avail. Can't I just have these colors as picked? Actually I promise, I would not complain about setting these things from scratch in each workspace again, but please, let someone tell me, how to get rid of Oomph functionality. PLEASE.

I guess there should be separate settings for Eclipse "style" and these should shared among Eclipse versions and instances (like via ~/.config/eclipse/ or what) and "environment" settings that are strictly involved in building/running the code that are tight to workspaces. I believe it would be way simpler to maintain the stuff. But at this point I just would like to know, how to disable Oomph to return to the old, well known hell. Is that even possible?

Answer 1

Everytime when I change pref in eclipse to ignore unnecessaryElse

org.eclipse.jdt.core.compiler.problem.unnecessaryElse = ignore

When I close eclipse, and restart it again. The above pref will be changed automatically to the following

org.eclipse.jdt.core.compiler.problem.unnecessaryElse = warning

Finally, I found that oomph alway Executing startup tasks to restore or change my pref settings. This is unacceptable.

At last, I add -Doomph.setup.skip=true to eclipse/eclipse.ini, and now oomph nolonger restore or change my pref settings.

-Doomph.setup.skip=true
