As of Tuesday, June 21, 2016, all build.gradle files need to reference an updated maven repository hostname, nexus.poynt.com. It used to be nexus.poynt.co however, that has been deprecated effectively immediately. The documentation has been updated to reflect this change (see here).
Any project that is referring to a host on the domain name poynt.co should be updated to poynt.com.
NOTE: Java package names have not changed. They’re still co.poynt.*.
