[SOLVED] How install custom branding module in openmrs?

I followed all the steps for installing OpenMRS. I downloaded the OpenMRS core source code and then executed mvn clean install in console. Then execute the command mvn jetty: run in the webapp directory and everything worked right. So, I downloaded the custom brading 0.2(.omod) module from openmrs modules repository and I copied this in .../Application Data/OpenMRS/modules and then execute mvn jetty:run for launch. I get the following errors:

anyone knows it could be? Note: My internet connection is behind proxy and the commands of maven worked because I set the proxy in the settings.xml file.
