I am trying to build the software Online-Whiteboard (<http://code.google.com/p/online-whiteboard/>) using maven. According to the website linked above, I need to use the follow command:

```
mvn jetty:run

```

However, when I run that command I get the following error:

```
[ERROR] Failed to execute goal on project whiteboard-showcase: Could not resolve

```

I've never used Maven before, so really have no clue what I am doing here; I tried looking up what this could be but couldn't find anything (helpful). Any help is appreciated.
