I would like Eclipse to automatically save every time I edit a file, in much the same way that it builds automatically. Because I've been using IntelliJ for the last year (which saves automatically by default), I keep having the following problem:
- Make some changes in Eclipse
- Forget to press save
- Run the build, unit tests, and notice some strange behaviour
- (Some time later....) realize that the unexpected behaviour occurred because I forgot to save the changes
Is there any way I can make Eclipse save automatically?
Eclipse Neon (4.6)
Window > Preferences
General > Editors > Autosave > check Enable autosave for dirty editors > choose the value for autosave interval (in seconds)
Details in M7:
Auto-save of dirty editors is now available in Eclipse. The autosave option is disabled by default. A new autosave preference page (Preferences > General > Editors > Autosave) is available and allows to enable/disable the autosave and change the interval of autosave. The countdown is reset on keyboard activity, mouse click, or when a popup is displayed (e.g. content assist, preference page, ...).
You can go here and check the box Save automatically before build
Windows > Preferences > General -> Workspace
You can do it with the saveDirtyEditor plugin as referenced in this question/answer. There is no non-plugin way of doing it.
First, try Window -> Preferences -> General -> Workspace. There you can check "Save automatically before build" and "Build automatically."
If that does not work,
PLEASE TRY
Preferences -> Run/Debug -> Launching -> "Save dirty editors before launching"
I wrote an Eclipse plugin for this called smartsave. It's available in the Eclipse Market Place.
It saves your files at a specified interval and you can even tune it to prevent saving if errors, or warnings, are present in the preferences dialog.
In Helios this can be done by going to preferences and setting:
Run/Debug > Launching > Save required dirty editors before launching
For Eclipse Mars 2, the settings are below Window > Preferences > General > Workspace. These settings are in minutes and not in seconds.
You could go to Windows > Preferences > Autosave and set the auto intervals to 1.
