Re: [recommenders-dev] Problem while building Code Recommenders

Hi,
It seems like Maven cannot connect to the repositories and download the required libraries.
Are you connecting internet through a proxy?
If you are, you should change the proxy settings of Maven configurations. This link[1] will help you to do that.

The procedure you have mentioned above is correct. Make sure your code is built before you push.

Best Regards,
Madhuranga Lakjeewa

Hi,
I have downloaded source code by cloning the git repository and then
run the command mvn clean install but I am getting the following
error. I follow the following
instructions:https://git.eclipse.org/c/recommenders/org.eclipse.recommenders.git/about/

I am working on a computer running Ubuntu OS. I have tried
reinstalling maven but nothing changed. The only solution I found on
the internet is here:
http://stackoverflow.com/questions/16229129/eclipse-tycho-not-able-to-resolve-the-correct-dependency.
But I am not sure how to proceed.

Can anyone suggest me how can I solve the problem? Thanks.

**********************************************
One more question: I assume the following procedure to contribute to a
project of Code Recommenders. Please correct me if I am wrong:

clone the repository-> import the project using existing maven
projects command-> change the source code of a project-> test it
locally -> and then push the change to Gerrit Code review System

Thanks.
