now my question is how do I enable to download artifacts from different repository? is there any setting for Cloud9 workspace?

Answer 1

Your problem could be on the Maven version.

If you execute on the terminal:

$ dpkg --get-selection | grep -i maven

If you have something like maven2 you have installed on your environment the old version 2 of Maven. Apparently some goals or plugins are only available on the latter version 3.

So, on your Cloud9 environment you can install the version 3 like this:

$ sudo apt-get remove maven2
$ sudo apt-get install maven
$ export MAVEN_OPTS="-Xmx256m"

The last command it's to avoid your maven process to be killed by Cloud9 when it exceeds the memory boundaries with maven probably it will happend to you. [ It happened to me :P ]

You can read about this in more detail here: How to use Cloud9 with Maven?
