For now I downloaded "Android Support Repository and Google Repository" using below commands and now build is working fine.
/opt/android-sdk/tools/bin/sdkmanager --no_https --proxy=http --proxy_host=127.0.0.1 --proxy_port=3128 "extras;google;m2repository" /opt/android-sdk/tools/bin/sdkmanager --no_https --proxy=http --proxy_host=127.0.0.1 --proxy_port=3128 "extras;android;m2repository" Although this is good for timebeing, I will be interested to hear if someone can point out how can we set proxy, so that packages will automatically get downloaded during build.
