Missing artifact org.primefaces.themes:cupertino:jar:1.0.9 [duplicate] - maven

Question

(8 answers)
Closed 3 years ago.
I'm working on a project using liferay 6.1.1 and maven!
I have this error message in pom.xml:
Missing artifact org.primefaces.themes:cupertino:jar:1.0.9
even if the jar file is already there!
When I tried to deploy the project, everything goes well ... but the warning persists even if the project works good.
Any idea?
