Eclipse does not recognize this attribute, but you can configure HTML validation options to ignore it.

In the "Settings for HTML files" → "Validation" section, you can ignore the specified attribute names. If you want, you can enter the template here, for example data-* .

This warning does not appear with Eclipse Luna, so the upgrade to Eclipse should go away.
