> Python SDK currently supports Python-2.7 only.
> The Python interpreter & pip definition in pom.xml points to {{python2}} & {{pip2}} respectively. 
> Users with multiple Python interpreters installed might end up having python2 and pip2 pointing to their 2.6 installation. (This scenario happens mostly on OS X machines.)
> There is no single, valid name for the executables as different OSes install those binaries in various names:
> - CentOS6/EPEL: pip (python 2.6) & pip2 (python 2.6) & pip2.6 (python 2.6)
> - CentOS7/EPEL: pip (python 2.7) & pip2 (python 2.7) & pip2.7 (python 2.7)
> - Debian7: pip (python 2.7) & pip-2.6 (python 2.6) & pip-2.7 (python 2.7)
> - Debian8: pip (python 2.7) & pip2 (python 2.7)
> - Debian9: pip (python 2.7) & pip2 (python 2.7)
> - Ubuntu1204: pip (python 2.7)
> - Ubuntu1404: pip2 (python 2.7)
> - Ubuntu1604: pip (python 2.7) & pip2 (python 2.7)
> - OS X: pip (python 2.6) & pip2 (python 2.6) & pip2.7 (brew / python 2.7)
> - Windows: pip-2.7 (python.org based installer)
> To overcome this problem the pom.xml should be extended to determine the suitable Python interpreter & pip automatically, in a platform independent way.
