Hi Muhammad, Are you trying to build the riak-java-client from source? It looks like it. I guess those errors you have listed are from within eclipse. So, when maven downloads the internet, I mean the dependencies, it puts them in a special directory on your machine (your local repo). If you have not messed with your maven settings at all then your local repo is in your home directory, in a folder called .m2 ( ~/.m2/repository )
Eclipse needs to know about the location of your local repo. To tell eclipse where your repo is open eclipse preferences and chose Java -> Build Path -> Classpath Variables. If there is no variable for M2_REPO you need to create it. Hit "new" enter M2_REPO for name and chose "folder" and browse to ~/.m2/repository and hit "ok". If M2_REPO is already set just hit "Edit" and again browse to ~/.m2/repository and hit "ok". Eclipse will ask if it can do a full rebuild of your project, say yes and your problems should be over. In answer to your second question: if you run mvn those jars will be in your local repo (~/.m2/repository). Otherwise you will have to find them on their respective sites (commons http client, apache commons, commons logging, google proto bufs etc.) I recommend you use maven to get yourself started.
