Empty Errors in Eclipse Problems View

Question

I recently converted my work dev environ from Idea to Eclipse. I've got everything in and building properly, but I have 23 empty error messages in my Problems view. I can still build everything despite these errors, but it is quite annoying to have the "Errors in project" popup when building.

The project "Web_ImageViewer" is a GWT project.

I have a hunch that these errors are somehow related to ignoring GWT output folders, but I'm not sure.

I can delete these errors, but they just come back. Anyone have any idea how I can permanently get rid of these? Or if they are actually trying to tell me something useful?

(I can't post an Image since I'm a new user)

Answer 1

Check the Problems tab "Type" column to see what validator the errors are being generated from. If the errors are useless, try turning off that kind of validation and doing a clean and build. Go to Preferences > Validation at the global level, or turn off validation for individual projects by right-clicking project > Properties > Validation

I regularly turn off my HTML validator since the HTML isn't well-formed when you are working with JSPs.

Update

Seems like a lot of people are narrowing unknown errors down to the Web (2.2-2.4) Validator. Try turning that one off and rebuilding.

Answer 2

I narrowed it down to "Web (2.2-2.4) Validator". After disabling it you need to Clean the project for the error to disappear.
