Maven downloads metadata.xml even after setting 'updatePolicy' to 'never'

Question

I use Maven to handle the dependencies and also Nexus as a repository manager. In my new project, I have several dependencies for which Maven downloads metadata.xml files every day. Since they are released versions , I just don`t want maven to spend some time downloading these files.

Here are the dependencies in pom.xml 

    <dependencies>
    <dependency>
        <groupId>org.apache.maven.shared</groupId>

I considered this question and also this one. They suggest setting UpdatePolicy to never for releases or snapshots in settings.xml or pom.xml , but it did not solve my problem. What are the possible reasons for this? Any other solution?

If you have updated ~/.m2/settings.xml and the metadata is still downloading each time, check the $MAVEN_HOME/conf/settings.xml file. (you can quickly determine $MAVEN_HOME by the results of "mvn -v")
