eclipse option (luna) to turn quick fix back on - eclipse

Not sure what i typed by accident, some key sequence, and a popup appeared/disappeared in luna eclipse editor. After that the quick fix stop popping up, which is kinda handy for imports and new classes. It Quick fix continues to work in other projects in same workspace, and in other work spaces. Been through the options, can't find one. Replaced luna, still no go. Looked throug project files, still don't see it.
Any ideas, other than create a new project?

Rescuing eclipse from bad workspace/project data

I would like to take a step backwards opening eclipse without it automatically opening the source files which were last open, nor the projects which were last loaded, I have reason to believe this might clear it all up.
Motivation being that as of a forced quit of eclipse, after it had gone stuck after some project changes, my eclipse Luna is no longer able to start without getting hung up again.
How may I accomplish that?
It's important to me not to lose my settings such as syntax highlighting and stuff, while performing the salvation... and whereas I am pretty certain I could locate my workspace directory on disk, would be nice finding where does eclipse keep the pointer to it, just to make sure I'll be tinkering with the right workspace, if needed..
I guess I could call it "starting eclipse in safe mode" :)

How to avoid Eclipse blocking keyboard shortcuts

I installed a plugin that allowed me to create UML diagram from my code. Everything was working fine until I found that now all keyboard shortcuts (like CTRL-X, CTRL-Z, CTRL-SPACE, CTRL-SHIFT-F,..) except for CTRL-C and CTRL-V now require a click on a small square that appear on the bottom right corner. And this is required every single time.
This are few examples of the square that appears:
If I click on the message or press Enter I can access the functionality. Does anyone know how to get rid of this annoying thing or at least reset Eclipse related configurations?
Thanks in advance
EDIT:
I obviously tried uninstalling the plugin but nothing changed.
Try Window / Reset Perspective as the duplicate shortcuts may be still in the perspective.
Also try restart specifying -clean option to rebuild the workspace metadata.
The pop-ups you are seeing are the "keybinding conflict" popups. These are common when you have two different plugins defining the same keybinding and looks like these. Still in your case there's only one option to choose from and it definitely looks like a bug.
In the Eclipse bugtracker database there are two issues that are looking like the one you have: #377048 and #374942.
These issues are marked as fixed in 4.2-I20120410-0633. So if you are having Eclipse 4.2 without any service releases installed, you would probably have this. The solution is - to use a newer Eclipse version. Eclipse 4.3.1 is available to download since today, and it should contain a lot of other fixes since 4.2. So I encourage you to install it.
The other solution could be to try playing with keybinding dialog (Window->Preferences->General->Keys) and trying to unbind and re-bind the commands that you are having issues with.

Strange eclipse display issues

I use Eclipse Java EE IDE for Web Developers for most of my coding, html, css, php etc etc. Recently however I have noticed an issue where after doing a combination of "something" the display of my files completely screws up and does all sorts of weird things.
For example if I try and add a on starting to do it the characters just start going all over the place and giving me display issues like that shown in the attached screenshot.
It's a little tricky to explain exactly what's happening but eclipse basically becomes unusable as each keypress seems to do something random and mess up the page even more.
Does anyone have any idea what might be causing this? I'm using a mac on Snow Leopard with Eclipse Indigo.
Just to update this. To resolve this issue I ended up downloading the latest version of eclipse and overwriting the eclipse directing with this. I tried just doing an update but this did not work so I'm guessing I had some corrupt files or something.
The good thing about eclipse is that you have a workspace folder that is essentially separate, so if you replace eclipse you can just re-import your old workspace.
ALl seems to be working as normal so far!

Eclipse: Refreshing known types in Java project

If you press Shift+Ctrl+T or choose "Navigate > Open Type..." you get the "Open Type" dialog for quickly navigating to a known class. When you start typing a name only the classes for which the name matches stay visible. That way you can find a class of which you know the name very quick without having to browse through the package explorer tree.
This has been working great for me up until this morning. All of a sudden for a couple of my projects I am only seeing some of the types that exist. Of course I tried the obvious steps of refreshing the projects, cleaning the projects, re-building the projects, rebuilding the projects externally, but all to no avail. It is a bit odd since the types are known in other places. If I add an import statement Eclipse does not complain that it doesn't know the type and I can Ctrl-Click through the types to get to their file. However, the type navigation knows nothing about them.
In the past when InteliJ used to do this to me I would go find its cache files and delete them forcing it to rebuild. Does Eclipse have something similar I might do (I'm an Eclipse newbie)? I am using Eclipse 3.4.2 and I have it configured to not delete files on a clean (because our actual build process puts files into the output directories that I don't want Eclipse mucking with).
Have you tried closing and reopening the project? Only types from open projects are held in memory, and the refresh occurs when you Shift+Ctrl+T for the first time on a newly opened project.
Edit to add: Ctrl+Shift+R also displays the types (along with everything else) but it also supports the Camel-case thing to find the Java types quickly.
Close eclipse and delete any .index files and the savedIndexNames.txt file in workspace/.metadata/.plugins/org.eclipse.jdt.core once eclipse is restarted it will rebuildl the entire index for Ctrl+T
try starting eclipse with the -clean flag, you can add this to your eclipse.ini which can be found in the same directory as you eclispe.exe, or if you start eclipse using a bat or shell script, add it as a startup argument, e.g. eclipse -clean.
The clean will tidy your workspace, and should force eclipse JDT to recalulate types. Ive had issue with .snap files (with seem to be created on dirty shutdowns) that seem to corrupt my workspace until I clean them up, not long ago eclipse lost the Object class!! made for some interesting errors!
I get problems like this often. I tried your solution, noticed it seemed to rebuild its search index, but I still couldn't find any of my classes. Then I took a look at the little green arrow on top right corner of that dialog, and noticed I had a working set selected which belonged to another project. I find it a little dumb that Eclipse doesn't warn you about this or anything, since this can be a very annoying little detail that one tends to forget (me at least ;-)).
Anyways, clicked on "Deselect Working Set" and bam I can find my classes again. Thought I'd add this here since others may make the same mistake.
This worked for me -
Select your project in Package Explorer
Press F5 or Right click and select Refresh
I used the "-clean" as first line in the eclipse.ini (version Juno) and worked like a charm.
I'v tried all the answers and I still had the issue. I then tried this:
I deleted the project (it's a maven project) and re-imported it. This time I made sure i check the "Add Project(s) to working set" checkbox. After that Eclipse was able to find the classes in that project.
The problem must have started because I didn't check this checkbox when i first imported this project.
By the way, I'm using Neon
(Warning: Shameless marketing ahead)
If you like this feature, you would love nWire. nWire allows, among other things, to quickly search not only for types, but for any possible Java element like method or field. It also uses a navigator view which is non-modal. After searching you can see the class associations in a very quick and easy way. Check out the video on our site.

Eclipse Search Menus disabled randomly

I use Eclipse 3.3 in my daily work, and have also used Eclipse 3.2 extensively as well. In both versions, sometimes the Search options (Java Search, File Search, etc) in the menu get disabled, seemingly at random times. However, with Ctrl+H, I am able to access the search functionality. Does anyone know why this happens? Has it been fixed in Eclipse 3.4?
window > close all perspective works for me.
Using Eclipse 4.3(!) this happened to me after doing a case-sensitive search.
Window -> Close All Perspectives didn't fix it and neither did restarting Eclipse using -clean. While messing with the search box, I discovered that simply clicking to a previous search entry allowed me to edit it and search again! Clicking back to the case-sensitive search grayed the option out again.
So before you reset anything in your workspace, try pulling up an older search entry using the Down Arrow.
I think this answer is what you all need to solve the issue on all versions.
I am using RAD 8 and I have also faced this problem than I removed org.eclipse.search directory in (workspace currently using) workspace/metadata/plugins folder then restart the eclipse.
That's all.
I don't have an exact answer. I will recommend that you try to correlate the disablement with which perspective is active. Likewise, which view is active. I have been using 3.4 and not experienced this issue.
Darn! I have that problem too -- in Eclipse 3.4.2.
Seems to be related to Navigator and Project Explorer views:
- Switch to Debug perspective: Search menu items are there.
- Switch to Java or Java EE perspective: Search menu items still there.
- Click on a project in Navigator or Project Explorer: Search menu items all DISABLED.
(Curse! I use search in Selected Resources a lot! )-:
Hmmm... It may slso depend on the file type currently open in the editor. (Like Java vs xml.)
Still present in Eclipse 3.5.2 -- and for the first time really sticky.
I checked out the "close all opened files and open any other file afterwards" answer and that brought back the Search menu items. Additionally, if you were lucky and have the Search result view open, than indeed there is this little link "Open search dialog".
By the way, additionally lots of other project-related menu items seem to be greyed out also together with this, and they did not reanimate :-( But I did not really check out if these are only items for which it is useful and planned to be greyed out in this situation.
I'm using RAD 7.5.1 which runs on Eclipse 3.4 and I get this problem frustratingly often. It doesn't matter which perspective or view I'm in, or which editor I have open.
Restarting RAD usually clears it up, but because that's such a colossal pain, I found that you can get around it in the Search View, there is a link; "Start a search from the search dialog" which will bring up the search dialog.
This isn't a great workaround because the link only shows if you have no search history. To do another search, you'll have to clear your search history in the view.
A late comment for anyone getting bitten by this, but I found "eclipse -clean" fixed it => this does a cleanup of the workspace before starting
Thanks http://letsgetdugg.com/2009/04/19/recovering-a-corrupt-eclipse-workspace/ for the tip, after I guessed my workspace might be corrupt.
Before search, check you may choose scope in empty Working set. Most Search menu disables Search button when you choose it. And mine, too :)
window > close all perspectives worked for me too.
But if you are just looking for a text search in the project you could press Ctrl+Alt+G on a marked text
I couldn't get it to work even when restarting Eclipse.
Here's what worked for me: Closing all open files and opening a different file. The different file happened to be .java, but not sure if that had anything to do with it.
I get this problem from time to time.
In the past I've fixed by starting eclipse with the -clean option.
Once when that didn't work I created a new workspace.
I followed these instructions for those two solutions.
The clean option didn't work for me today and I found this thread because I didn't want to create a new workspace. The closing all files and reopening one file did work however.
I had this issue also in eclipse 3.6.2: Helios Service Release 1.
Closed all the editor windows, and the search has been enabled.
Switching to another perspective, then back, works quickly for me.
I've faced similar issue in Ctrl+H "File Search" tab. The "Search" and "Replace" button was grayed out (disabled). The solution is fill the "File name patterns" text box (for eg, *.py). May be this is by design!
I have this problem with MyEclipse 7 (eclipse 3.4) under Debian Lenny. Perspective doesn't seem to matter. I get around it with the shortcut Ctrl+H but I was hoping for a better way.
Just had this problem in Eclipse Neon 3. It is a very common problem in RAD. I could find using in the console, then switch back to the source and search. RAD would disable the find/search options per source file open. This is very frustrating.
I had this problem too. It appeared when I installed the m2eclipse plugin.
I had not found a solution, but you can use Ctrl+H shortcut instead.
And you can navigate between tabs with Ctrl+PgDown or Ctrl+PgUp keys.
I've uninstalled the following pluings and it worked.
Maven integration
PMD
eclipse checkstyle plugin
EclEmma (coverage)
I don't know which of those cause the problem. To uninstall a plugin: Help -> Software Updates...-> "Installed Software" tab.
