How to display line numbers in Eclipse

by

By default, Eclipse’s editor will not display line numbers, it’s no good for debugging. Here’s a tip to show you how to turn on the “display line numbers” feature in Eclipse.

In Eclipse IDE, select “Windows” > “Preference” > “General” > “Editors” > “Text Editors” , check on the “Show line numbers” option.

Very helpful – I’m surprised that eclipse doesn’t display line-numbers by default, essential for de-bug especially as line-numbers are reported in LogCat. Thanks again, Neil

In Mac OS , you have to go Eclipse > Preferences > General > Editors > Text Editors or use short command “CMD+,” and than follow General > Editors > Text Editors
