Maven local dependency authentication error - maven

Question

I have a JSF application that use Primefaces, where I've created a custom theme that Primefaces use for the presentation. The theme is placed in a JAR file that I have added as a local Maven dependency.
After months of not touching the code, I made some minor changes today. When trying to build the application, I get an error saying that it failed:
Failed to read artifact descriptor for nivis2:nivis2:jar:2: could not transfer artifact... etc.
When trying to show Artifact details in NetBeans I get some more information:
Error resolving project artifact: Could not transfer artifact
nivis2:nivis2:pom:2 from/to PrimeFaces-maven-lib

I haven't really changed anything and I'm not sure how to interpret the error message - does it try to copy my JAR-file to an external Primefaces repository? Why now all of the sudden?
Regardless. I only need to be able to use the custom Primefaces theme and maybe there are better ways of doing that than this?

Answer 1

Which maven goal are you executing?
If you run mvn clean deploy, use mvn clean install instead.
The install goal will put the built artifact in your local repository under your .m2 folder in your user home, the deploy goal is used to deploy your artifact to a remote repository.

Answer 2

Thank you all for helping me. I got it working in the end through installing the latest version of Netbeans and re-creating the POM. I don't know what or both of this solved the problem or exactly what was causing it in the first place, but now it works.
Once again, thanks for taking your time looking in to my problem.
