How can we run eclipse in clean mode and what will happen if we do so

Question

I often get suggestion to open Eclipse in clean mode. So, how to run in clean mode? and what happens if I do so?

Answer 1

if set to "true", any cached data used by the OSGi framework and eclipse runtime will be wiped clean. This will clean the caches used to store bundle dependency resolution and eclipse extension registry data. Using this option will force eclipse to reinitialize these caches.

How to use it:

• Edit the eclipse.ini file located in your Eclipse install directory and insert -clean as the first line.
• Or edit the shortcut you use to start Eclipse and add -clean as the first argument.
