How do you clear the validation errors in Eclipse?

Question

I accidentally clicked on "Validate" for all of my projects (instead of going to Team > synchronize...) and I have several validation errors and tons of warnings.

I can't figure out how to clear these so it goes back to just having the standard errors.

(One way is to go to "Configure Contents" of the "Problems" view and deselect the validation errors, but I know they're still there, just hidden... it bugs me that they're not actually removed)

I've tried restarting eclipse, tried cleaning all projects but that doesn't clear these validation errors.

Answer 1

You should be able to select all the offending markers in the Problems View, right-click and choose Delete from the context menu. Clean-building causes all builders to remove only the markers that they produced, but these markers weren't produced by a builder (you created them through an explicit invocation of the "validate" command.)

Answer 2

I'm not aware of a built-in way to clear them all. You might try deleting the markers file in

[workspace dir]/.metadata/.plugins/org.eclipse.resources/.projects/[project name]
