XML namespace http://primefaces.org/ui showing warning that no tagLibrary exists for that namespace

问题

I am facing a strange problem with my local workplace in Eclipse. I found out that many people faced the same issue with Maven + Primeface earlier, but unfortunately I didn't get any concrete answer what is the reason of this error. May be I am not going to the right place. That is why posting the same question again

Below are my configurations:

Buildpath looks like:

All the jars are also there in maven dependencies:

But after deploying it is glass fish server, I am getting the below warning:

Warning: This page calls for XML namespace http://primefaces.org/ui declared with prefix p but no taglibrary exists for that namespace.

Any help? Thanks
