Line Numbers in Eclipse

It’s 4am in the morning. You’ve been coding in Java for the past 6 hours and realise something’s missing from your Eclipse editor .. something that can confirm that the last 6 hours weren’t a WASTE of time..

and that is line numbers.

To turn on line numbering in Eclipse, simply do the following;

1) Windows -> Preferences
2) General – > Editors -> Text Editors

and click the “Show Line Numbers” checkbox.
Whola?

Now was the last 6 hours a waste?

    Eclipse Helios doesn’t have General in Preferences

  49. player_03 says:

    roco: In that case, try Gerard’s suggestion: right-click the bar where the line numbers should be. The option will be in that menu as well.
