NLS missing message: CANNOT_FIND_FACELET_TAGLIB

Question

I am getting this warning in Eclipse:

NLS missing message: CANNOT_FIND_FACELET_TAGLIB in: org.eclipse.jst.jsf.core.validation.internal.facelet.messages ICEfacesPage1.xhtml /myapp/src/main/webapp

On the following lines:

xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"

Any ideas why, and how to solve it?

This is an Eclipse quirk. Try one of the following things:

Close/reopen project.
Rightclick project > Validate.
Project > Clean... and clean selected project.
Restart Eclipse.

The above is the sort of generic advice that I give to new users. Closing the project worked for me, but not validating. Eclipse is bad mojo. – Mike Feb 23 '15 at 02:53
For me, none worked, I don't know if it's related, but I'm using Debian. – ptkato Mar 20 '15 at 01:00

This was also the case when I imported a JSP taglib, for example:

<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:fmt="http://java.sun.com/jstl/fmt">
</html>

I closed the project and reopened, and it worked!

I realize that this is an old post but I hope this may help somebody. I recently installed the ICEfaces plugin (IF-3.3.0-IM-1.3.0-Eclipse-4.3-plugins-B.zip) for Eclipse 4.3 (Kepler).

I created a New ICEface Facelets Composition Page using the page creation wizard.
