Eclipse saves configuration even when removed - eclipse

I'm in trouble with Eclipse configuration. I had Eclipse Juno with a certain configuration (perspectives, opened views like Logcat, console, etc), I removed it from my system and downloaded Eclipse Luna.
When I opened it the first time and selected the Workspace, Eclipse loaded the perspectives used in Juno (for example Remote System Explorer) but those perspectives weren't installed in Eclipse.
This also happens with the Logcat view, Eclipse Luna hasn't installed ADT (Android) and Logcat wasn't available.
Why is this configuration loaded if I removed Eclipse completely?

The workspace contains the information about the perspectives, views, ... in use.
So if you install a version of Eclipse without some of the plugins you were previously using you should probably create a new workspace. You can import your projects from the old workspace (but if the projects reference any of the old plugins you may get errors).

Eclipse Neon 2 & 3 keeps Resetting the Workspace and Plugins

Have installed Eclipse Neon 3 x86_64 bit on macOS Sierra...
Proceeded by picking a workspace folder and installed the following plugins:
Subclipse 1.10.13 (by dragging the icon on to the workspace from https://marketplace.eclipse.org/content/subclipse)
Installed the following plugins (by going to Help -> Install New Software -> All Available Sites and expanded Web, XML, Java EE and OSGI Enterprise Development):
Eclipse Java EE Developer Tools 3.8.0.v201701262139
Eclipse Java Web Developer Tools 3.8.0.v201702270442
Eclipse Web Developer Tools 3.8.2.v201702270442
JST Server Adapters 3.2.400.v201606081655
JST Server Adapters Extensions 3.3.501.v201609071751
JST Server UI 3.4.300.v201606081655
Everything works (plugin functionality) but everytime I close Eclipse, it brings up the default dialog asking for a workspace and is completely fresh (no plugins and preferences...). I have to manually install these plugins every single time I restart Eclipse!
I've deleted the following directories and files:
~/.eclipse (folder);
~/Library/Saved Application/org.eclipse.eclipse.savedState;
~/Library/Preferences/org.eclipse.platform.ide.plist;
~/Library/Caches/org.eclipse.platform.ide;
And, also unzipped Eclipse into a different folder and specified a new workspace and after installing the plugins and restarting Eclipse, its completely fresh again!
This is very annoying and also disappointing...
I even tried to put -clean as the first line of the eclipse.ini file but it didn't help any...
What's weird is that this is happening on my company issued MacBook Pro but not my personal MacBook Pro (which is the exact same model and year as the company issue one)...
Any suggestions would be most appreciated!
Have you checked Eclipse Bugzilla for a similar issue?
It looks like you are running into this:
Bug 507328 - Eclipse forgets about global settings and installed features
It's a feature of macOS introduced with Sierra called "App Translocation" or "Gatekeeper Path Randomization". Try unzipping Eclipse and moving it (drag and drop) with Finder to a different location. This should set a flag which disables Gatekeeper Path Randomization. However, it's important this this is done from within Finder.
The Eclipse Oxygen packages will ship as DMG which will motivate users to drag and drop the Eclipse.app bundle into the Applications folder using Finder. There is an Apple bug here where Apple explicitly states that Finder may be able to opt an app out of Gatekeeper Path Randomization.
To check whether Gatekeeper Path Randomization is happing in Eclipse perform the following:
Open Eclipse > About Eclipse
Click Installation Details
Navigate to tab Configuration
Check the value of osgi.install.area property
If it points to some random looking path with /var/private that path randomization is in effect.
The situation may become more complicated in future macOS versions, though.

Eclipse doesn't save the previous settings like workspace & Plug-ins

I am using Eclipse Neon on my MacBook & every time I start Eclipse it prompts me for my workspace again and again even though I set it as my default one.
Same goes for the plug-ins I have installed , I need to install eclipse decompiler every time I load eclipse.
I get an error like : "This wizard helps you to import and reinstall previously installed plug-ins. It is triggered because
either you are launching eclipse for the first time or your Eclipse has been updated."
Can someone please assist me with this issue ?
I had the same problem after updating my Mac to Sierra: Eclipse would not remember the default workspace. After moving Eclipse into the Application folder, the problem disappeared.
The issue seems to come from a Mac OSX Sierra feature called 'path randomization' (see eclipse bug 507328). The actual solution to avoid the path randomization seems to be for eclipse to provide signed .dmg images (bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=461670).
Two workarounds that I can suggest are:
Start from the eclipse oomph installer when installing eclipse (see https://www.eclipse.org/forums/index.php?t=rview&goto=1754574#msg_1754574)
Start the actual eclipse executable file instead of opening the .App container

Newly created PyDev Project not showing up in Eclipse Neon PyDevPackage Explorer

I just installed Eclipse Neon. I also have Eclipse Mars still lying around on my system. When I opened Neon it asked if I wanted to convert my workspace and I did.
So I installed PyDev through Help/Install on Neon and now I go to File/New/PyDev Project and follow the prompts to create a new Python project. It does not show up in PyDev Package Explorer. If I try to create it again with the same name, it says I cannot because the project already exists.
When I first installed PyDev, 3 projects showed up in the PyDev Package Explorer, but they all contain folders underneath which cannot be expanded so I don't think those 3 projects are being handled correctly either. Actually they are closed projects I see, but I see at least 1 is a Java project, so it does not belong to that perspective.
So any idea why Neon/PyDev is not handling my Python projects correctly?
So from the above comments, there were two defaults for PyDev Package Explorer I was not expecting when I installed Neon (which may well not just apply to Neon, but other versions as well)
Display working sets was the default behaviour and I wanted display projects.
I wanted non-Pydev projects filtered out and they were not

Installation of FindBugs plugin with Eclipse IDE for Java EE Developers

I'm struggling to get the Eclipse FindBugs plugin to work and am sure there's a schoolboy error being made somewhere.
I extracted the file findbugs-2.0.2-rc2.zip to a local folder C:\Program Files\findbugs-2.0.2-rc2 and running findbugs.bat, FindBugs works fine running it over a local Java (Eclipse) project.
I added the FindBugs update site, it found "FindBugs Feature, 2.0.1.20120712" and installed it. Restarting, right-clicking on an open Java Project doesn't display the "FindBugs" option (that this video shows).
I looked in Window > Preferences to try to find a way to inform the plugin of the local FindBugs installation (in Program Files), but couldn't find anything.
Uninstalling "FindBug Feature", I tried extracting the FindBugs Eclipse plugin zip file into Eclipse's plugins folder, but after a restart, saw no difference.
Help > About Eclipse > Installation Details > Installed Software lists "FindBugs Feature 2.0.1.20120712".
Can anyone please offer a pointer on where I'm going wrong here? Thanks!
Windows 7, Eclipse IDE for Java EE Developers Juno SR1, JDK 1.7.0_09, FindBugs 2.0.2-rc2
As suggested above, problem is likely caused by not having appropriate write access to the C:\Program Files\Eclipse\plugins folder.
Solution:
Close Eclipse. Restart Eclipse as Administrator (right click - Run as Administrator). Reinstall plugin. Restart Eclipse.
It looks like the Findbugs plugin wasn't installed properly and/or disabled by Eclipse. There can be several causes.
Multiple versions of the same plugin. To make sure this isn't the case, remove all Findbugs versions (installed manually and via the marketplace), and reinstall one (preferably via the marketplace). Watch for any warnings during installation.
There is a (dependency) conflict with another plugin. However, if this is the case I think Eclipse will warn in the log which other plugin is the cause of the conflict.
Rights problem. Make sure you have write permissions in the main Eclipse folder and all it's child folders.
I remember reading somewhere that installing Eclipse under the C:\Program Files\ in Windows can also be causing problems. Try moving Eclipse to a different folder, e.g. C:\Eclipse
Hi I also faced the similar problem but from my own experience i can suggest you the solution :-
Plz ensure that you are using eclipse version 3.6 or higher. findbugs 2.0 is not compatible with Eclipse 3.5(Eclipse Galileo).
1) Plz extract the findbugs zip file into eclipse folder(wher your eclipse is installed). This will automatically move findbug plugins into eclipse plugins folder. Restart the eclipse and you will find findbugs option on right clicking on project.
2) if 1 step does not work plz remove all the findbug jars for the eclipse plugins folder and place the complete folder into the eclipse dropins folder. Restart the eclipse and you will see the difference.
You can follow these step's to make findbugs work in your eclipse.
1.Install FireBug plugin from marketplace.
Help->Eclipse Marketplace ->then search for FindBugs
2.Configure FindBug for your project
using Maven Without Maven
This worked fine for me using eclipse juno.

Cannot find installed plugin on my Eclipse IDE after update

I have updated my ubuntu desktop and the eclipse which i was running on the system got updated automatically. After the update all the options inside the eclipse are the same as they used to be by default.. all my customization has been lost and the perspectives, project templates are no more. Now when i tried to installed the plugins, eclipse returns me that the selected plugins has already been installed..
I want to know is it common with eclipse to show this behavior after each update? How to can i get back my old customization without deleting the installed plugin folder and install them from scratch again..
I didn't met the issue you mentioned before. but I suggest you can check whether your workspace location is changed after your plugin is installed/updated.
Actually, all your eclipse plugins configuration/preferences settings are stored into your {workspace_home}.metadata folder. it's not relevant about what plugin eclipse has installed, That's the reason why each time switch workspace, you need to re-customized preferences settings.
So, if you want to protect customized settings, pls consider backup .metadata folder properly.
