How can I show line numbers by default in Eclipse?
Found it somewhere on Google...:)
Window → Preferences → General → Editors → Text Editors → Show line numbers.
Edit: I wrote this long ago but as @ArtOfWarfar and @voidstate mentioned you can now simply:
Right click the gutter and select "Show Line Numbers":
As simple as that. Ctrl+F10, then N, to Show or hide line numbers.

Eclipse has a search feature in the top left box of the Preferences. Type in 'line numbers' in that search box, and presto...
In case you're tired of googling each time you forget...
If this doesn't work it may be overridden by your current settings. You can right-click in the bar to the left of the code where line numbers would normally appear and turn them on with the context menu.
On a Mac do this:
cmd + , or ADT -> Preferences
Expand General -> Editors ->Text Editors
Check box: Show line numbers
Slight variation on Mac OSX:
Eclipse → Preferences → General → Editors → Text Editors → Show line numbers
The top answer is good but you can also bind it to a key ( shorcut ) to toggle it..
Window > Preferences > Keys then enter "Line Numbers" in filter and bind it to a key.
I use CTRL + S + L.
Windows → Preferences → General → Text Editors → Show numberlines

make sure the parameter
is NOT 255,255, 255, which is white
the eclipse changes the perferences's position
to eclipse -> perferences
this will be the appropriate solution for asked question:
String lineNumbers = AbstractDecoratedTextEditorPreferenceConstants.EDITOR_LINE_NUMBER_RULER; EditorsUI.getPreferenceStore().setValue(lineNumbers, true);
