This was me. With the "Gradle STS" Eclipse plugin. In the end I managed to find an answer. IIRC, you went Run --> External tools... something something. Haven't looked at these things for a month or two so I've forgotten.
I recently reinstalled Eclipse, and was aware that we're told "Gradle STS" is on the way out and really quite contemptible... all the people at the bleeding edge are switching to Buildship like crazy.
Fair enough, OK, I shall yield to this intense pressure to drop Gradle STS ... but how might I launch a task (even the last task) not having to use the mouse? I HATE... :-( being forced to use the mouse.
"Workaround" (hardly brilliant): Ctrl-F7 will take you from window to window (Ctrl-F6 just navigates through editors).
So you can arrange your Gradle Tasks window in such a way that you can still see your console window ... and then Ctrl-F7 to where you want to go.
"Workaround" (slightly better): Ctrl-Shift-L twice to get to the "customise hotkey" dialog. Give a key binding to "Show View (Gradle Tasks)".
Would welcome any answers which involve use of menus...

I am trying to run my projects in Eclipse, whenever I used to run any program a window appear and it shows that project is launching and building.
This never happened before. In fact, it was working very okay an hour before but now, even for old created project it showing this and not moving ahead.
Is this a general thing happened in eclipse as I haven't seen this before.
I want to get out of this to move ahead and to run the project.
The Launcher looks like this :
The progress Bar is also not moving ahead if it's building the project.
It's definitely normal to see; there's times I'll see it two or three times in a day. It shows up if the launching process is waiting on anything or is expected to take more than a couple seconds.
In your case, it seems to be stuck on "Building workspace," which happens when you open Eclipse. The more projects you have in Eclipse and the more sections of workspace you have (groups of tabs), the longer it takes to build your workspace. So I'm going to wager a guess that you tried to launch a project within the first minute or two of Eclipse being open. Am I right?
If that's the case, just wait a bit, and watch the lower right corner (where it says "Launching Clock" in your screenshot). When it shows it's stopped trying to do start-up tasks, you should be good to go.
If Eclsipse had been open for a while, then perhaps Eclipse is busy with other junk and calling it "Building workspace." Maybe it's having a hard time understanding what to do with one of your projects, so check for compiler errors. You can also try to "clean" your projects (Project -> Clean).
If that also fails...hmmm...I'm sure there's other options before you get to this point, but you might need to re-install Eclipse. I suppose there's a chance that in the deep dark corners of Eclipse, a file was corrupted, causing Eclipse to hang on a task that requires a missing/bad file. But before you go this far, make you get second or third opinions, because I might be missing some simpler cause of your Eclipse hanging than what I've listed already.
I found the solution.
I don't know what was the error and why it was displaying the Launcher window and stuck there. But, I forcefully stopped eclipse using Task Manager and then restarted it.
When restarted it took few minutes (more than usual time) and I was done with it. now it's working okay.
Re-installation of Eclipse also worked but i tried this before re-installing or upgrading.
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.
When I click the run/debug button on eclipse it tries to activate it using javaBeans.
The problem that I deleted JavaBeans. Another thing is when I choose run/debug As... I have only the option of javaBeans despite the fact that I have regular java and android installed on my computer.
How can I fix it? In other words how can I get rid of this javaBeans?
[SOLVED]
For all those who stumble upon this thread. You can find the solution here
I am not sure if I understand your problem, but instead of pressing the "run" button, press the little drop down triangle next to it. This will bring up the run configurations. From here you can delete and edit existing configurations (such as your java beans) one, and create new ones (using different configurations).

Are there any low-hanging fruit regarding some more efficient way to run and test Eclipse-plugins (within the PDE)? Besides slimming down the Eclipse-configuration, which has already been done.
I usually minimize my launch configuration itself (not sure if that is what you are doing). Here's how I do it:
Create a new launch configuration
Go to the "Plug-ins" tab
Select "Launch With:" -> "Plug-ins selected below only"
Click on "Deselect All"
Select only the plug-ins you are debugging from your workspace
Optional: You can uncheck "Include optional dependencies..."
Click on "Add Required Plug-ins"
Save the configuration and launch
Now, this might not work in the first shot. This probably means you have an issue with the defined dependencies. This is also a good test for that as well. Fix it, relaunch, and it should run much smoother.
I use Launch As: Eclipse Application and I don't find it to be too bad. I've found that changing the plugin.xml (or fragment.xml) always requires you to quit and respawn to pick up the changes, but changing Java doesn't always as the changes can often be hot-swapped in. (PDE is good at warning you when it can't.)
I'd like it if Eclipse could dynamically insert my plug-ins into the running environment -- it can do this with regular plug-ins. As for speeding up the edit-compile-debug cycle, I normally prototype my work in small SWT / Swing applications before integrating them into the full product, but this might not work in a lot of cases.
Is there any way to save my code folding in eclipse?
It's horrible to scroll trough my entire UI declaration. (And yes, I googled it! :)
The question is very similar to Is there a way to collapse all code blocks in Eclipse? .
I'm re-posting my answer there here.
The question is a bit old, but let me add a different approach. In addition to the above hot-key and utility approaches, there are default preference settings that can be toggled.
As of Eclipse Galileo (and definitely in my Eclipse Version: Indigo Service Release 2 Build id: 20120216-1857) language specific preferences can open up new files to edit which are already collapsed or expanded.
Here is a link to Eclipse Galileo online docs showing the feature for C/C++: http://help.eclipse.org/galileo/index.jsp?topic=/org.eclipse.cdt.doc.user/reference/cdt_u_c_editor_folding.htm .
In my Eclipse Indigo I can open the Folding Preferences window via : menu/ Window/ Preferences/ Java/ Editor/ Folding and set all options on so I can open files by default that are completely collapsed.
Amongst other things, Mylyn allows you to fold/hide content and persist the state.
Mylyn monitors your work activity to identify relevant information, and uses this task context to focus the user interface on the task-at-hand. This puts the information you need at your fingertips and improves productivity by reducing searching, scrolling, and navigation. By making task context explicit Mylyn also facilitates multitasking, planning, reusing past efforts, and sharing expertise.
Once Mylyn is enabled it will start folding/hiding the content. If you have an active task (can use a local task repository) the state should be persisted between sessions. Alternatively you can attach the state to the task (sorry don't have Eclipse to hand to check the exact method to do this) then retrieve it. This is useful if you are sharing tasks with others.
I know this isn't exactly what you were asking, but this was really helpful for me:
Ctrl+Numpad_Multiply can also be used
to expand all
Ctrl+Shift+Numpad_Divide is bound to
collapse all
Ctrl+Numpad_Divide toggles folding on
and off
(Taken from this post: Is there a keyboard shortcut in Eclipse to fold the current method/block? )
This, and plenty other issues of Eclipse made me switch to JetBrains IntelliJ IDEA. It's worth sneaking a peek at it if you find Eclipse's performance annoying, need more control on your code formatting or if you just want to have your code foldings persisted.
I'm not using it for too long now but it seems pretty handy for anyone developing in the Java, Android or Scala corner.
