How to disable usage of public maven repo - maven

Question

I've setup a maven repository(Artifactory) in my LAN which has no internet access. I've also change my maven settings.xml to use this internal repo only. However when I try to create a maven project, it still try to access the public repo(http://repo1.maven.org/maven2) for some downloads. Where has I done wrong?
For example, when I perform the following:
mvn archetype:generate -DgroupId=demo.john -DartifactId=struts2demo
-DarchetypeGroupId=org.apache.struts
-DarchetypeArtifactId=struts2-archetype-starter
-DinteractiveMode=false
there is the following waring reported:
... ...
[INFO] Generating project in Batch mode
[WARNING] Error reading archetype catalog http://repo1.maven.org/maven2
org.apache.maven.wagon.TransferFailedException: repo1.mavne.org
at org.apache.maven.wagon.shared. ...
... ...
Sometimes the it build successfully with this waring, but sometime it won't.
Below is my maven's settings.xml
