There are preferences one can turn on in Eclipse that are useful but may not be turned on my default.
- 'Refresh automatically' - If you find yourself needing to manually refresh files in projects, you can turn on the 'Refresh automatically' preference. Go to the menu for Eclipse->Preferences, click on the "Workspace" preference (without expanding that preference) and you will see 'Refresh automatically' checkbox near the top under the 'Build automatically' checkbox.
