When a file (.java for example) is open in Eclipse, how do I get the Package Explorer to show the file that I am working on?
There is a button in the Package Explorer view that looks like two yellow arrows pointed at left and right. The tooltip is "Link with Editor". Click that.
I've found that constantly syncing package explorer with editor causes package explorer view eventually to grow too long, especially with large projects. I've instead mapped a keyboard shortcut to sync package explorer with the editor. If you are using mylyn this is of course a smaller problem.
Key mappings are available at Window ⟶ Preferences ⟶ General ⟶ Keys ⟶ Show In (Show In Target Id: Package Explorer). Mine is Ctrl+Alt+⟵, be welcome to copy.
In Luna Command name has changed a little. Instead of Show In (Show In Target Id: Package Explorer) command is now Show In (Package Explorer).
From this site:
How to use Show In functionality from the popup menu
Press Alt+Shift+W while you’re in an editor. This pops up a menu with a number of choices. The choices will vary depending on what plugins you have installed. Select the option you want and press Enter.
The fastest way to select an option is to use the first letter of the option, eg. to go to the Package Explorer, press P (you may have to do this 2 or 3 times depending on how many other options start with P). The press Enter. You could also use the arrow keys.
Invoke "Show In" faster with a keyboard shortcut
If you frequently use one of the options (eg. Package Explorer), you can map a single keyboard shortcut to invoke it.
Go to Windows > Preferences > General > Keys.
Search for Show In. Eclipse will list a number of Show In options. In
our case we want Show In (Show In Target Id: Package Explorer).
Select the command you want, enter a key in Binding and you’re done.
Always link active source file with package explorer
If you like this feature, you can open the package editor and click on the double yellow arrows to always show the currently selected source file in the package explorer.
There is a double arrow icon at the top of the Package Explorer that toggles this behaviour. click on It
In your Eclipse .java file editor, right-click anywhere, then "Show In-> Package Explorer".
As shown:
As you can see, you can also open file in Navigator, Outline and so on with this.
Above project explorer window you will see the below image in the red circle , just clicked on this one mean when clicked any file in the project will showing you in project explorer.
If you want to show only one file you can
1 - Click right on the file .
2 - Select show-in .
3 - Select show in project explorer .
4 - Done.
The below image explain more about it .

How can I open all source code files in a eclipse project at once? It takes too long to open all files in large projects by expanding out the packages and clicking on all the files.
I would like to know how to do this so I can ctrl+e to classes quickly.
It is not a good way to keep open all source files in a project because a project may have hundreds of source files. There is NO direct way to open all source files in eclipse.
However you can do it in two ways:
Using open resource dialog:
Create a working set which includes your project. Refer this.
Press Ctrl+Shift+R and select the your working set(Click on the downward pointed triangle button)
Type *.java in the text box. Dialog will list all java files in your project. Press Ctrl+A to select all files. Click on open button.
Using search dialog:
Select your project in Package explorer/Navigator/Projects view.
Press Ctrl+H. Go to File search tab. Leave "Containing text:" as blank. In File name patterns text box enter *.java. In scope section choose Selected resource option. Press search button. All source files will be displayed in search view.
Change the view layout of Search view to Show as list(In search view toolbar click on the downward pointed triangle button)
Press Ctrl+A to select all results. Right click and select open option.
I am more familiar in Eclipse and need the IntelliJ equivalent. In Eclipse, I could open a java class, right click, show file in package explorer and it would highlight the file on the left. What is the IntelliJ equivalent.
You can highlight a file you have open in the editor in a number of views using the Select In...menu that can be opened using ALT-F1 when the editor window has the cursor.
The most usual ones (Project/Packages) are found under the menu opened by ALT-F1 and then right arrow.
You can also double click the circle/cross button ontop of the Project view
it will show you the current active file in the project structure
You can turn on Autoscroll from source in Project Tool Window so that the file/class to the left is scrolled to as soon as you open a file for edit.
If this option is on, IntelliJ IDEA automatically navigates from a file in the editor to the corresponding node (file, class, field, method, etc.) in the Project tool window.
Note that selecting this option makes the Scroll to Source button unavailable.
It is called "select in project view".
You'd better edit your keymap ! (alt+F1 right arrow is not very efficient...)
file > settings > keymap > select in project view : alt+E for example
You can press Alt-Home, it goes to the navigation bar.
Go to or select the package by pressing left arrow.
Press F4 now to see it in the project view.
How do I compare two files using Eclipse?
(Currently I am using WinMerge.)
To compare two files in Eclipse, first select them in the Project Explorer / Package Explorer / Navigator with control-click. Now right-click on one of the files, and the following context menu will appear. Select Compare With / Each Other.
Just select all of the files you want to compare, then open the context menu (Right-Click on the file) and choose Compare With, Then select each other..
If one or both of the files you wish to compare isn't in an Eclipse project:
Open the Quick Access search box
Linux/Windows: Ctrl+3
Mac: ⌘+3
Type compare and select Compare With Other Resource
Select the files to compare → OK
You can also create a keyboard shortcut for Compare With Other Resource by going to Window → Preferences → General → Keys
Other than using the Navigator/Proj Explorer and choosing files and doing 'Compare With'->'Each other'... I prefer opening both files in Eclipse and using 'Compare With'->'Opened Editor'->(pick the opened tab)...
You can get this feature via the AnyEdit eclipse plugin located here (you can use Install Software via Eclipse->Help->Install New Software screen):
http://andrei.gmxhome.de/eclipse/
If your compairing javascript you might find it not displaying.
https://bugs.eclipse.org/bugs/show_bug.cgi?id=509820
Here is a workround...
Window > Preferences > Compare/Patch > General Tab
Deselect checkbox next to "Open structure compare automatically"
Compare with Other Resource – The Easy Way using Eclipse (no additional plugin required)
To assign a keyboard shortcut to the feature, go to Window > Preferences > General > Keys, look for the command Compare with Other Resource and assign it to a keyboard shortcut of your liking. See How to manage keyboard shortcuts in Eclipse for more details on configuring shortcuts.
Tip: Alternatively, you could press Ctrl+3 (for Quick Access) and search for Compare with Other Resource. This way you don’t have to configure a shortcut but you’ll have to search for the command every time in Quick Access.
Once the shortcut is assigned, you need to select the source file from the Package Explorer, Project Explorer or Navigator. The easiest way to do this from an open editor is to assign a shortcut to instantly show the file in the Package Explorer or, if it’s not open, to open it quickly using the keyboard.
Now press the keyboard shortcut you assigned to Compare with Other Resource and the following (non-modal) dialog should appear:
Troubleshooting: If the dialog doesn’t appear, it’s probably because you haven’t selected a file in either the Package Explorer or another view that allows file selection. Make sure a file is selected and make sure you haven’t selected the class in the Package Explorer rather than the actual Java file.
Now you can select the second file in the Package Explorer and drag and drop it onto the dialog. Click OK and the comparison editor should display, comparing the two selected files.
Tip: See the post on using shortcuts for common SVN commands for tips on how to navigate the comparison editor with the keyboard.
Comparing External Files
Using the Compare with Other Resource dialog, you can compare a workspace file with an external file or even compare two external files with each other.
Comparing a workspace file with an external file is easy: Once you’ve opened the dialog from a selected file, instead of dragging and dropping another workspace file, tick External File in the Right pane and then Browse to a file on your filesystem.
To compare two external files, you have to start the dialog again from a selected workspace file (choose an arbitrary file). Once open, select External File in the Left pane and Browse to your file then do the same for the Right pane.
Please refer this page for more details: http://www.eclipseonetips.com/2013/09/19/compare-two-workspace-or-external-files-in-eclipse/
If you have Beyond Compare installed, the ContextQuickie eclipse plugin has an option to enable it to be selected from the context menu displayed when you right-click a file.
Install from:
https://github.com/ContextQuickie/ContextQuickie/wiki/Installation
After install, activate Beyond Compare menu items via Window->Preferences->Context Quickie->check 'Enable Beyond Compare'.
Hi i many html editors in eclipse. each one provides different features.
Is there a way i can quickly switch the editor of current opened tab, ( other than open with option in the project explorer).
Lets say abc.html is currently open. but i want to open it in different editor. Now i have to search that file in the project explorer and then right click > open with. option.
OR
I use ctrl+shift+r to open any resource , it always opens in default editor. But i want to choose there which editor to open with" option there. :(. is there any shortcut for that?
I can well understand wanting to open stuff just using the keyboard.
I can think of 2 solutions:
1: CTRL + SHIFT + R (select file as normal) then (still in the Open Resource dialog) TAB, TAB, ENTER and then press the down arrow key until you get the right editor
2: Keep the Project Explorer 'Link with Editor' toggle on (a button on the top right of the Project Explorer View)
Now you can easily get from the file open in the editor to the correct place in the Project Explorer view (so you can right click on it).
Hope this helps!
(I also find CTRL + F7 a useful way of switching to the Project Explorer view from an editor)
In Netbeans, to the top left of where the code is, there used to be two panels, one called 'Projects' where you could click a project name to open a tree of all the directories and files in it, and you could double click a file to edit it.
Below it is the navigation panel which shows the class names, methods, etc contained in the file you're viewing.
I accidently clicked the close button on the projects panel and can't figure out how to get it to open again, any ideas?
In Netbeans 6.8 on Windows, going to Window -> Projects brings it back for me. CTRL + 1 works as the shortcut.
Click Window > Reset Windows will give you back the old state of all windows!
just go to Window in menu bar and select Projects
Window -> Projects
In NetBeans 8.2 Go to Window->Navigator in menu bar or press Ctrl+7 and select Projects
it will open a folder as work space .
