Upgrading any module on OpenMRS standalone 2.3 takes for ever

Hi,
I cannot upgrade any module on OpenMRS standalone 2.3. I am trying to add OpenMRS radiology module on OpenMRS standalone 2.3 and for that it needs emrapi 1.13. But emapi 1.13 omod file depends on other dependencies.
Following are the necessary dependencies:

providermanagement - version 2.3
uiframework - version 3.4
uilibrary - version 1.5
emrapi - version 1.13
event - version 2.2.1
reporting - version 0.9.8.1
htmlwidgets - version 1.7.0
calculation - version 1.1
serialization.xstream - version 0.2.9
metadatasharing - version 1.1.9
metadatamapping - version 1.0.1
I tried to upgrade any of the above dependencies and it takes for ever to finish the process. It keeps hanging. I tried couple of times on different machines (MAC, Ubuntu 16.04, Windows 10) at different times, different network. Still I am unable to upgrade any of the above dependencies.
Here is the log file:
