Using local maven repository and offline mode in network restricted / secured environment

Issue

• I am trying to setup local maven repository in a network restricted / secured environment, how do I prevent maven from connecting to internet.
• I have installed JBoss BRMS / BPM Suite 6 and the local maven repository, but the integrated maven is still trying to connect to public URL, for example, I see this log:

00:02:26,542 FINE  [org.apache.http.impl.conn.tsccm.ConnPoolByRoute] (pool-28-thread-1) Releasing connection [{}->http://repo1.maven.org][null]
... ...
00:02:26,646 FINE  [org.apache.http.impl.conn.tsccm.ThreadSafeClientConnManager] (pool-32-thread-1) Get connection: {}->http://repo1.maven.org, timeout = 0
00:02:26,647 FINE  [org.apache.http.impl.conn.tsccm.ConnPoolByRoute] (pool-32-thread-1) [{}->http://repo1.maven.org] total kept alive: 0, total issued: 2, total allocated: 2 out of 40
00:02:26,647 FINE  [org.apache.http.impl.conn.tsccm.ConnPoolByRoute] (pool-32-thread-1) No free connections [{}->http://repo1.maven.org][null]

• How can I setup offline mode for maven ?
• When I create/build a project via business-central in RHPAM offline env, I get the error.
