| Eclipse missing plugins on startup [message #1785686] |

Nearly every time I start Eclipse, it asks where my workspace is and needs to install my plugins all over again.
===============================================================================
INSTALLATION DETAILS:
I had a few different Eclipse installs on my Mac (HighSierra 10.13.4).
I deleted them all to start from scratch.
I installed:
Eclipse IDE For Java Developers
Mars.2 Release (4.5.2)
Build id: 20160218-0600
When I launch eclipse, it:
- asks where my workspace is, I tell it and check "Use this as the default workspace and do not ask again"
Eclipse - Help - Install new Software
Work with: "The Eclipse Project Updates - http://download.eclipse.org/eclipse/updates/4.5" for
- Click Disclosure Triangle next to Eclipse Java Development Tools
- select Eclipse Java Development Tools 3.11.2.v20160212-1500
Eclipse - Help - Eclipse Marketplace
- Search for GWT Eclipse Plugin 3.0.0
- install it
It needs to restart eclipse, I agree and it does so.
Everything now works fine, until I quit eclipse and later restart.
=====================================================================================
THE PROBLEM:
[Nearly*] every time I launch Eclipse, two unusual things happen:
1) It asks me where my workspace is (Screenshot1.WorkspaceLauncher.jpg), despite the fact that I always check "Use this as the default workspace and do not ask again"
2) It needs to reinstall the GWT plugins (Screenshot3.ImportWizard.Plugins.jpg)
There is also an oomph Exception thrown (sometimes before the import wizard comes up, sometimes after): see Screenshot2.Oomph.jpg)
Expanding on the cut off text: FileNotFoundException: /Users/Eclipse.app/Contents/Eclipse/configuration/org.eclipse.oomph.setup/installation.setup (No such file or directory)
I suspect this is the root cause, as that is not where Eclipse.app lives. Not sure why oomph is looking there.
Once I reinstall the plugins, everything works fine until I quit and relaunch.
* regarding "Nearly"... sometimes if I immediately relaunch after quitting, everything comes up fine without problems (1) & (2)
Appreciate any help!

Thanks for the reply Ed.
It turned out your questions led me to the solution:
High Sierra "translocates" applications in some cases: https://github.com/potionfactory/LetsMove/issues/56
This was happening to Eclipse. In a nutshell, when an application gets "translocated", a copy of the Eclipse.app package is made in /var/folders, and you run from there.
So my plugin installs were going to this temporary folder and then getting blown away when I quit the app.
For posterity: here are the answers to your questions
==============================================
Did you create your installation using the Eclipse Installer?
I installed by downloading:
http://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/mars/2/eclipse-java-mars-2-macosx-cocoa-x86_64.tar.gz&mirror_id=504
to
~/Development/EclipseReinstall.4.5.2/eclipse-java-mars-2-macosx-cocoa-x86_64.tar.gz
I then simply double clicked on the .gz file and it created the Eclipse.app package in that directory.
Why do you need to install JDT from http://download.eclipse.org/eclipse/updates/4.5 when Mars.2's Java package should already have the latest JDT 4.5 version?
I thought I needed to, but perhaps I didn't really need to. It installed successfully, I wouldn't expect that to cause these types of problems.
Are you saying the Import Wizard comes up automatically? I've never seen that before.
Yes.
You can try Preferences -> Oomph -> Setup Tasks and enable "Skip automatic task execution on startup"
The problem is not that the setup tasks keep executing... it's that the plugins are missing.
Doesn't Navigate -> Open Setup -> Installation open properly?
It does... and it showed that Eclipse had been translocated. This was the key piece of info I needed to solve the problem.
Is there some particular reason you install Mars rather than Neon or Oxygen (the latest release)?
That's what our project team is using
