How to get rid of the “Warning: trimming empty div” in Eclipse?

Question

How do I stop this warning showing in Eclipse?

Warning: trimming empty <div>

No, I absolutely cannot make the div non-empty, I cannot change the code.

Answer 1

Even though Ionut G. Stan's method does work, it is probably not the best way to do it, since it will disable this check on all projects."

A better way would be to disable that particular validation for that project only.

To do this right click on the project in the navigator (or package explorer, etc) and select properties. In the preferences you should see "Validation", expand it and select "HTML Syntax". Check the checkbox for "Enable project specific settings". Below this, under the elements section you need to turn off "Invalid empty element tag".

Answer 2

You could add an HTML comment inside that DIV or go to:

Window -> Preferences -> Web -> HTML Files -> Validation

and play a bit with those values.
