Is there a way to force Eclipse to save project / workspace settings? I can't find a "save workspace" or "save project" command.
(I've never had a problem with this in Eclipse, but TI's Code Composer 4 is based on Eclipse and it sometimes crashes and doesn't retain the changes I made in project settings.)
The surest way to force such a save would be to switch workspace.
Switch to an empty workspace, and then switch back to your current workspace: every project settings should have been saved and restored.
Note: the bug 27821 ([Workbench] saving state and preferences) is a duplicate of:
bug 2369 ([Workbench] Would like to be able to save workspace without exiting), which is opened since... 2001!
So even the "switching workspace" trick might not be enough to save every settings, but that is a start.
