Environment
In our discussion, we will leave the heavy details of network complexities behind us, and will describe our topology as a network which has different restrictions. All we need to acknowledge is that our network has different areas with different restrictions.
Maven Repository Workflow

4. Conclusion
In this quick tutorial, we saw how to prepare for Maven offline mode using maven-dependency-plugin. Also, we got familiar with both a command-line approach and a settings-based approach to enable the offline mode.
