Complete Removal of Eclipse plugin - eclipse

I use Eclipse Neon under Windows 10.
I installed a plugin (MonjaDB) using Eclipse Market Place. As I didn't find the plugin to be very useful I uninstalled it using Help->About->Installation Details->Installed Software->Uninstall. Sadly, however, this didn't seem to fully remove the plugin.
I now have a small red square on the right hand side of my workspace in the shortcut toolbar. This cannot be removed using the close option. I went so far as to remove my installation of Eclipse and the .eclipse directory in my home area but after a reinstall the square is still there.
Presumably this means that it is somehow associated with the project in my workspace?? Does anyone have any ideas how to remove this annoying square?
EDIT:
I have noticed two things
The MonjaDB perspective is hanging around somehow and
If I press the little red square on the right it opens an empty tab in the tab set to the right (where mylyn sits) with the title of DB Tree but I cannot remove it.
I have added three screen shots
MonjaDb perspective Partly Active

It seems like your current perspective is the one that was uninstalled. Just try opening a new one via the Open Perspective toolbar button that's close to thevred square, and then you can try right-click > Close on the red square.

At least a part of this is intentional...when the implementation class of a view no longer exists we leave the view 'open' but are supposed to show an "Error Part'. The reason to leave it up is to handle cases where a user has installed a new eclipse and opens his old workspace before installing the extensions. If we were to remove the views the user would have to set up their perspectives again once they had installed the extension.
Note that resetting the perspective won't work because the class implementing IPespectiveFactory no longer exists.
Closing the perspective and opening a new, different, one should work. If the perspective you open has visible views that are no longer available you should just close them.

Eclipse Neon CDT missing manage configurations button

I created a C project in eclipse neon and I am trying to delete some of the build configurations. However I can not get to the manage configurations dialog I am used to. The button seems to be missing. Did it go somewhere else or is my eclipse just buggy?
I think this window is supposed to look more like this. See how there is a manage configurations button next to the dropdown at the top.
I just tried switching workspaces and when I use a clean workspace I can see the button.
While the aforementioned hacks indeed work, such an approach is impossible when one already has many projects and now wishes to target another architecture.
I have found another way.
Right click on the project and select, from the pop-up menu,Build Configurations, and one of the menu items is Manage. This behaves as the disappearing Manage Configurations button.
PS: this is still a problem with Oxygen 3.

How to remove a "lost" task bar in eclipse

In my eclipse Mars I have two task bars with only red corners as items:
How can I remove this both task bars? I have already disable all checkboxes under "Window" - "Perspective" - "Customize Perspective...". The both toolbars are still there. Also I cannot do a left or right click on these both toolbars ...
EDIT:
Ok, after reinstalling the "JBoss Developer Studio" PlugIn I get (instead of the red corners):
But I still cant remove these toolbars ...
The file where the workbench layout is stored is
<your-workspace>/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi
I had something similar happen once and was able to manually edit that file (with some trial-and-error) to get rid of the duplicate, unwanted toolbars. I can't really recommend it, though, as it's a very error-prone process. If you do decide to attempt it, make sure to make backups of the file before you being.
Alternatively, you can try just deleting that file (rename it or move it somewhere else) and see if Eclipse will re-create it automatically.
A better alternative is probably to export your workspace preferences then create a new workspace. You can import your projects and exported preferences into the new one.

Eclipse: workspace is completely invisible

Something quite strange has happened: The whole Eclipse main window disappeared while I was debugging a Play Framework project. The Eclipse symbol in the applications bar still shows up as usual (from where I still can force Eclipse to quit).
My System (Ubuntu 14.04.) still behaves as if Eclipse was there, e. g. other applications get unfocused when choosing Eclipse in the applications bar. Meanwhile I have re-started Eclipse (that didn't help) and even re-started Ubuntu (still the same behaviour).
When I start Eclipse the workspace selection window shows regularly up. If I select another workspace, it also shows up regularly (I have created a second one to test that). Eclipse even still reacts properly on any shortcut as well as well as F10 & F11. It seems like the Eclipse main application window was "transparent". Therefore I assume that it is a problem of Eclipse resp. its workspace rather than an Ubuntu problem.
Does anybody have an idea where to maybe re-configure the workspace? Or is there even a secret function for all that?
Thanks a lot!!
Meanwhile I was able to re-get the window: I clicked on a shadow effect that sometimes showed up. I resized that shadow with my mouse. As an effect the Eclipse window top bar (the one above the menu) showed up again. Afterwards I could "pull out" the window from the bar - and there it all was again... But I have still no idea, how that happened - and what might be the solution if someone runs into that issue without having a shadow.

how to remove google sign in button in eclipse

I'm facing a wierd problem. My eclipse, has a google signin button which is occupying some of the space which I do not want to happen. Initially it had "Sign-in to Google" text along with it. I've followed some blog post and set accordingly to show just the icon (I don't remember that blog post link).
But now, the icon is getting replicating .. it is being shown 12 times. It is actually creating childs :P
I've gone through all the options present in Customize Perspective menu, none of them had this button listed. Can someone help me in removing that google sign button from my perspective? One possible suspect is- my eclipse crashes when I suspend and wakeup my machine.
You can use the Window > Reset Perspective... menu command to reset the perspective to its default state, which might eliminate that toolbar and buttons. If that fails, I would create a new workspace and import the projects into it using File > Import > Existing Projects into Workspace.
If you want to try to salvage your existing workspace, it's possible to do so my manually editing Eclipse's internal file that stores your Workbench layout, but it's a bit tricky. Here are the steps I've followed to eliminate a similar repeated toolbar item:
Exit Eclipse.
Find the Workbench layout file, it's path is <workbench>\.metadata\.plugins\org.eclipse.e4.workbench\workbench.xmi. Make a backup of this file before you touch it - this is essential because it's easy to corrupt the file if you change the wrong things.
Open the file in your favorite XML-aware editor - most packages of Eclipse include the XML editor that works just fine1, but be aware that if you use Eclipse to edit the file you can't have Eclipse open on the workspace that contains the workbench.xmi you want to edit.
Find the section of <trimBars> nodes in the XML; from there you have to determine which <trimBars> node you need to edit. In your case it looks like a vertical one, probably with a side="Right" attribute.
Under the correct <trimBars> node you'll find multiple <chlidren> nodes, each with an elementId attribute that should help you identify it; you're looking for <children> nodes that are identified as something related to the Google plugin.
Delete the <children> nodes that seem related to the unwanted toolbar buttons. In your case, it appears that there is an entire toolbar that you might want to eliminate, so you might want to delete the entire containing <trimBars> node.
Save the file and start Eclipse on that workspace.
1Some packages of Eclipse include EMF tools that will open it in a special XMI editor that does not provide a view of the source, only a structural tree view. Depending on how you like to work with XML, this might be easier than editing raw XML.
This is not a perspective but a view. You can hover over that bar with the buttons and click Alt+Shift+F1 to check where this View comes from. Then you can either disable/uninstall the contributing feature (Help -> Installation Details) or check where the feature came from.
If it comes from the IDE, you can open a bug for it. If it is contributed from a third party plugin, contact the developers of that plugin.
There is an eclipse bug concerning duplicate view toolbar buttons in Luna that has recently closed as well. Maybe this solves your problem as well.
Edit: Taken from this bug:
root cause is that in Luna 4.4M5 WorkbenchWindowControlContribution.createControl is called twice, the
first time with a null value for
WorkbenchWindowControlContribution.getWorkbenchWindow() while it is
still being created. This is related to what has been reported here
https://bugs.eclipse.org/bugs/show_bug.cgi?id=427452
second cause is that my createControl(Composite parent) method was calling PlatformUI.getWorkbench().getActiveWorkbenchWindow() instead
of WorkbenchWindowControlContribution.getWorkbenchWindow(). This
resulted in an attempt to create a new Workbench Window, which
recursively calls createControl() again. This has already been
reported here https://bugs.eclipse.org/bugs/show_bug.cgi?id=366708

How can I close an empty pane in Eclipse

I often end up with lots of empty panes in Eclipse that can only be minimized but not destroyed. How do I close these?
Update:
In this screenshot you can see two minimized on the upper left and several on the right hand side. In the center are four more. They only seem to be restorable in the Debug mode.
http://img406.imageshack.us/img406/9900/eclipse1.png
this happened to me, too. What worked for me (based on FilmJ and douncon's comments) was to open a class file, then drag that tab over the top of the empty pane.
Select Window -> Reset Perspective. That should reset the current perspective (what you call "mode") to its' initial state, (hopefully) closing all irrelevant views.
Something seems terribly wrong with your Eclipse. Maybe you should reinstall it. It is possible that you installed a buggy plugin.
First of all, what do you mean by pane? Eclipse has:
Windows (Eclipse itself, e.g. instance)
Documents (tabs)
Views (properties, tasks, explorer, etc)
If by 'pane' you mean document editors, you have problems either with your Eclipse version or most likely one of the installed plugins.
Each View also can be closed (except maybe some project types (perspectives) of which I'm not aware). For CDT (C/C++) you can close practically everything.
I'll recommend you download latest Eclipse version with no plugins, extract it to different folder, and check if that happens again. If yes, please explain more in details (like Eclipse version, perspective you are using, any side plugins, etc).
Also a good places are Eclipse community forum, mailing list and bugz :-)
I had the same problem. For me it helped to go into the right perspective and activate the functionality that caused the window in the first place. Once I reactivated the functionality, in my case "QNX Memory Analysis perspective", I was able to close all the windows one by one.
The conclusion is you have to refill the empty windows with content and then you will be able to close them properly.
So, it's really very easy for this to happen, if you open an editor that's incompatible with the existing editor, you can often end up having to place it outside of the tab list in one of your editor panes, then you might clear or copy that, typically while trying to add that view to a tab list.
In any case, what it's done is create a new editor, and all you need to do is drag some file to that empty editor window giving it some form of context, then close it.
I had the same issue. I followed #zvikico, but instead of just resetting, I first reset and then closed all the perspectives. Please follow the following to fix the problem. It worked for me:
Window -> Perspective -> Reset perspective..
After resetting follow below:
Window -> Perspective -> Close All Perspectives
