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):

If your compairing javascript you might find it not displaying.

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'.

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.
What are the shortcuts for the context menu actions "Team -> Synchronize with Repository" and "Team -> Update" on the whole project?
I have already found shortcuts, but these are executed only on the file i have currently opened. But I want to execute it on the whole project without having to scroll the project explorer to the top and right-clicking on the project.
If there are no such shortcuts, how can I create them?
As john.k.doe indicates, that's the right solution, but you also need to do something else in order to make the shortcut actually work, which is go to Window > Customize Perspective > Command Groups Availability and there just check the SVN box ;)
you can almost always get the key shortcuts you want by
go to preferences type "keys" or go to General -> Keys
in the field presented when you click on "Keys"
in the left pane, type the command you are interested in setting up a shortcut for:
the image below is from my mac, but it works the same way on windows/linux, you just might choose something besides Cmd-Y as your shortcut modifier. the U under User indicates that i was the one to add that modification.
I have written a small Eclipse plug-in which selects the active project in the Package Explorer so you can execute other actions (like 'Sync with repo' and 'Update') on it. I think this approach is more flexible compared to writing a plug-in that selects the project and executes a predefined action.
You can get the plug-in at http://code.google.com/a/eclipselabs.org/p/eclipse-tweaks/downloads/list, it is named "com.xakcop.select". Download it and put it in the dropins/ folder of your Eclipse installation. Then when you restart Eclipse, you will find a new command Select project in Windows->Preferences->Keys. The default key binding is Ctrl+Shift+Backspace but you can change it to whatever you want.
When you are in the Java editor just press Ctrl+Shift+Backspace, this will select the project that the current file belongs to in Package Explorer. Then press the shortcut for "Synchronize with repository" and you are done.
The source code of the plug-in is also available as part of my eclipse-tweaks project: http://code.google.com/a/eclipselabs.org/p/eclipse-tweaks/source/browse/com.xakcop.select
I think the answer to this question adresses the issue.
The quickest way I've found to update/synchronize, after having set the shortcut keys, is to click on the minimize button in the Project/Package Explorer and then press the keys. After the update, simply clicking on the last used file in the editor returns to the previous workspace state (provided the "Link with Editor" button in Project Explorer is selected).
I should clarify: I use a working set for each project. The working sets are displayed as default Top Level Elements in the Package Explorer so, by clicking on the minimize button the desired Project' working set, they collapse and are easy to select. Then, I apply the shortcut on the selected working set.
From my point of view, the problem is the focus of the commands you execute.
The Team commands Snychronize and Update are executed on the current object (In my case). As you noticed, when you execute the command on the project, the project is synchonized - when you do it on a file, only the file is synchronized.
What I did as workaround is the following:
I created Key-Bindings for the commands Show in (Navigator) (Alt-N), Go to (Alt-G), and Show View (Naviator) (CTRL+SHIFT+Q, N).
With Alt-N I show the current File in the Navigator. I can then use the keys to navigate to the root that I want to synchronize (it's not always the whole project for me). If the root is to far away I use Alt-G and type the Project or Folder where I want to go to and execute afterwards the Synchronize commands.
(Go to works only in the current view)
If you have selected the Project once you just have to switch to the navigator (Show View command) and execute your synchronize commands.
You could also use rgerganov's plugin then you would not have to execute as many commands.
The procedure works also with other views (package explorer, project explorer)
What about this approach? It should also work for other SCM's or commands you want to execute on any object in the explorer views.
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 .
I have many types of file in my eclipse workspace, so i want some files to be open in a particular editor. say a war or a jar with winrar. sql with some eql developer, xml,s with xml editor etc how to set that? so that whenever i open them, they should open a assigned editor.
there is an entry in the eclipse preferences that associates file types with editors. You select your file type (e.g *.html) and assign it one of your installed editors.
On Mac OS, the preference you want is:
Preferences -> General -> Editors -> File Associations.
Goto
Window-Preferences
then
General->Editor->fileAssociations navigation
then
select or add the extension in the right top dialog
then click add on the right bottom dialog, select the appropriate application and save :-)
You want to add an entry in the Preferences for General->Editors->File Associations.
If I've got a file open in Eclipse, how can I figure out where it is on the filesystem?
For example, in Vim I would use :pwd.
Use the Eclipse menu:
File->Properties
or the shortcut:
Alt-Enter
You should be able to see the Location associated with the Resource
Just hit Alt-Enter.
The other solution ("File-->Properties" or "Alt+Enter") didn't work for me.
I use:
Right Click (in current editor) --> Show In (shortcut: Alt+Shift+W) --> Project Explorer
This shows in Project Explorer the location of the file. If the file is a class in a referenced library, the dependency tree is automatically opened.
What you're looking for is the 'Properties' dialogue for the current file. This can be activated in two ways:
Selecting from the menu: File -> Properties
Using the shortcut: Alt + Enter
This gives you a dialogue which contains both the full path of the document, as well as the relative path from the workspace root.
The dialogue can be quite handy: it allows you to highlight and copy the file path.
Linking to Project Explorer won't work if you have many files - it will select the right file in the list, but it won't "scroll" to that portion so it is visible.
You'd have to manual scroll the Project Explorer view to see where the file is. It could also be nested so deeply that the full location will be obscured by truncation.
Another way to quickly (keyboard-free) see the path is to hover over the file type icon (on top of the open editor window).
Eclipse also has the ability to link the explorer view with the current file, so that whenever you change a file, it is expanded and selected in the explorer view.
Just look for the following image at the top of the view:
