Namely, I am working on a "New project wizard" plugin. When new project is created I open my perspective to display the project there. It is displayed as expected, but I can not run it since I can not see "Run configurations" menu item under my "Run" menu. I've been looking for a way to get this menu item back with no success. Now, I got curious why is it invisible. Someone knows it already?
Use Window > Customize Perspective.
Look at the Command Groups Availability and select Launch.
You may also want Launch on Tool Bar Visibility.

Suddenly my project explorer window has disappeared from Eclipse. I try selecting Windows > Show View > Project Explorer, but nothing happens. What can I do?
Try Window --> Perspective --> Reset Perspective.... Remember that your own settings, if any, will also be reset.
Try to close Eclipse IDE and reopen it and
click on window->show view->project explorer
For me it was like this...
Window->Show View->Other->General->Project Explorer
Or
Window->Open Perspective->Other->Java (default)
Open Eclipse IDE
Enter "Project Explorer" on Quick Access (Search text box).
Either select from drop-down or press Enter
Window -> Perspective -> Reset
Reset the IDE
Window -> Show View -> Project Explorer
Select Window->Show View, if it is not shown there then select other. Under General you can see Project Explorer.
If none of the above solutions work, Try Window-> New Window
I had encountered the same problem as well. The following solution helped me to get over it:
Window -> Show View -> Package Explorer.
You can use the shortcut as well. It's Alt + Shift + Q, P
Using the latest Luna upgrade.
The only solution that worked was Window >> New Window.
It's very easy to lose that critical bar.
If you are on either Eclipse or Spring tool suite then follow the below steps.
(1) Go to 'Window' on the top of the editor. Click on it
(2) Select show view. You should see an option 'Project Explorer'. Click on it.
You should be able to do it.
Close the current perspective:
Reopen it using Window -> Open perspective.
i had also encountered this issue.
.
This Solution worked for me....
windows->navigation->maximize active View or Editor(ctrl + M)
.
in the screen you can see on left side navigation menus ... now click on those buttons one by one ....you will get your solution...
Try changing the perspective to JavaEE and then check.
Not sure if this is problem but, this ticked me off for a while since I did not realize what was happening at first - maybe this will help others.
Its not really a problem, just the way Eclipse works. (I'm use to Visual studio)
Its all about Perspectives!
I set up an (existing) PHP project in eclipse(neon) and then tried to configure and run debug. A Popup "Confirm Perspective Switch" is shown - I selected "Yes", not realizing what it actually does. The "perspective" then changes and you no longer see the project explorer anywhere. You cant "open" the project explorer window from top nav > window > show view, since its no longer there (which is BS, it should show something that gives you indication of current and other "perspectives" - at least for newbie.) No where now does it give project explore options.
Now you must change the "perspective" back from debug to PHP (at least in in my case).
This can be done a couple ways, easiest is from the icons on right top right side side. One icon would be the "bug", and next to it is the PHP icon. Just click the icon "perspective" you want. The other way is from top nav bar > window > Perspective > open Perspective, then select PHP. Could they hide this any deeper?
I know this is likely second nature to those who have used eclipse for a while, but was frustrating to me (on day one) till I figured out what was going on.
Please Select window in tool bar
Move to show view
Select project explorer
applied the same method to reset the perspective, no changes appaired then I restart the Eclipse IDE which was fine then.

Is there a way (plugin) in Eclipse to open detached windows which can be put on separate monitors: e.g one monitor will have my source, second threads and variables? The feature is in IntelliJ.
Yes. From the "Window" menu select "New Window". You can also drag the tabs off of the main window and a new window with just that tab will be created.
If you want a window with just the source code by itself, dragging the tab with the source in it won't work. What you can do is create the new window, drag the source over and minimize any other existing tabs within the new window to essentially leave a "source code only" view. You should be able to save this as a perspective and name it "Editor Only". This is somewhat cumbersome to setup, but once you have the perspective saved it should be pretty easy to get in and out of.
This is available in Helios and possibly earlier versions.
You can right-click on the title of any "View" and choose "Detach", this way you won't need two mail windows.
Whenever I hit Debug or Run in Eclipse, I get a dialog asking me what configuration I want to use.
How do I set a default configuration and bind a keyboard shortcut?
Maybe this article from Eclipse One Tips will help you:
How to run the last launched application
The answer lies in a preference hidden on the Run/Debug page:
Go to Window > Preferences > Run/Debug > Launching.
Select the option Always launch the previously launched application. It’s located at the bottom of the dialog.
The preference should look something like this:
Now you’re free to press
F11, Ctrl+F11 or click the Run/Debug
icons on the toolbar with confidence, knowing it’s going to run what
you expect it to run.
One question arises: How do you quickly run a class as a specific
application (eg. a JUnit test) if you can’t press F11 to
run it? You have some options available:
The fastest way is to use keyboard shortcuts. Eclipse allows you to launch classes using a keystroke, including JUnit tests, Java
applications, etc using Alt+Shift+X.
Alternatively, right-click on the class and select Run As. The submenu will show available options for launching the class.
Lastly, you could click the pulldown arrow on the run/debug icons in the toolbar and select Run As. The submenu once again shows
available options for launching the class.
Eclipse plug-ins that add new project types may contribute 'Launch Configurations' to control how Eclipse executes the application. For example, J2EE based projects need to publish content and start the application server. Contrast this with simply starting a JVM for a regular Java application.
When you select a configuration, Eclipse records this for future use. You can access these by selecting the 'Run/Run Configurations' menu item or selecting 'Run Configurations' from the little drop down menu next to the run and debug toolbar buttons. You can also add new launch configurations through the Run/Debug Configurations dialog that opens. In this dialog, you should see one or more configurations that you previously launched. Selecting one reveals all the info Eclipse uses to launch your application. One tab called 'Common' contains options for controlling the your favorites menu. Checking the box next to Run or Debug will add this launch configuration to the top of its corresponding menu.
If you only have a single configuration in your menu then Eclipse will launch it when you click the associated button. If you have more than one then Eclipse launches (sometimes) the most recently used. I say sometimes because, occasionally, one launch configuration causes another to launch, which cause the last used configuration to be the second one when you would expect it to be the first one. Usually this happens to me when I launch an application, which needs to be built and the build launches a tool. When this happens, just select the correct launch configuration from the drop down menu.
You can bind a keystroke combination to the Run and Debug commands through the 'Windows/Preferences' menu item. Then select 'General/Keys' in the tree control on the left.
Sometimes when opening projects, NetBeans will display a "Task scanning" progress bar on the status bar. What exactly is it scanning for? Is it possible to turn it off as I noticed that sometimes it takes a while and maybe it's just my installation but sometimes I have to force it to stop when closing NetBeans.
It is a "Task List" plugin working. It does this:
Provides the Task List window, which lists places of interest in your project, such as lines that contain "TODO", "XXX", "PENDING", Java compilation errors, and so on. You can click an entry in the list to navigate to the corresponding place in your code.
You can remove it by going to "Tools > Plugins" menu, "Installed" tab, selecting "Task List" from the installed plugin list and clicking "Uninstall" button. (These instructions are for NetBeans 6.5, but should be somewhat alike for all the other versions).
But I would advise against removing it - I find it pretty useful. There are times when I forget about several TODO's, and Tasks window is a great way to look 'em up.
If you can't see that window, you can access it through "Window > Task" menu, or by pressing Ctrl+6 (again, these instructions are for NetBeans 6.5)
Using Neatbeans 7.2.1
You can go to Tools->Options->Miscellaneous then under the Files tab uncheck Enable auto-scanning of sources. Whenever you want to have Netbeans scan you project you can go to Source->Scan for External Changes.
Tools->options->C++, or whichever language you are working with, under the Other tab uncheck Reparse on File Change. Whenever you want to reparse right click your project Code Assistance->Reparse Project.
It is scanning for the // TODO blarblar and // FIXME .... alikes.
You can disable it by removing the plugin.
In Netbeans 7.0.1 you can't disable the Task List definitively.
Instead you can limit/avoid scan :
Right click in Tasks window
Filter -> Edit
Unselect all
You can also cancel the running "Task scanning" process :
Right click on the progress bar
Click Cancel process
