Did you check that you can access the repository? Is the pom/artifact available in the repository? If so, check the local ~./m2/com/xyz/list folder if the artifact or an error message is there. Delete and re-try if required.

i realized that i have to add more dependent maven projects to the build path, and do mvn clean install and after a laborious 2 hours the thing is fixed!

In some cases (my case in particular) some additional security tweaks might be involved.

What I mean is that if you work with a central repository that available through a certificate, you might have to check if your JAVA_HOME\jre\lib\security\cacerts file stores the certificate in question. In my case after importing the certificate file in there (I used the KeyStore Explorer application, but it can be done on the command line either) and all my processes continued normally.
