Failure to transfer org.apache.maven:maven-artifact:pom:2.0.6 from

Failure to transfer org.apache.maven:maven-artifact:pom:2.0.6 from http://repo.maven.apache.org/maven2 was cached in the 

 local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. 

 Original error: Could not transfer artifact org.apache.maven:maven-artifact:pom:2.0.6 from/to central (http://

 repo.maven.apache.org/maven2): No connector available to access repository central (http://repo.maven.apache.org/
 maven2) of type default using the available factories

I finally resolved the problem, it was such a kind of cleaning, here are the steps

-Right click on project Run as/maven clean

-Right click on project Run as/maven install

-Right click on project Maven/Update project and check the option: Force update of snapshots/releases

-Restart STS or Eclipse IDE
