How do I compare two files using Eclipse? Is there any option provided by Eclipse?

Question

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:

1. Open the Quick Access search box

   • Linux/Windows: Ctrl+3
   • Mac: ⌘+3

2. Type compare and select Compare With Other Resource

3. 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.

Here is a workround...

• Window > Preferences > Compare/Patch > General Tab
• Deselect checkbox next to "Open structure compare automatically"
