Starting JSPM in force mode

Why its required:
As per JSPM default behavior, JSPM does not allow to deploy an SCA with the same version (release, SP-level, patch-level) as an already deployed component. 
In SDM we had force deployment option where we can depoly the SCA or SDA irrespective of their version.Starting Netweaver 7.1 SDM has been totally replaced by JSPM and we want to have the similar force deployment option in JSPM.

How to start JSPM in force mode :
1. Go to /usr/sap/<SID>/JC<XX>/j2ee/JSPM .(On UNIX like environment , please setup DISPLAY as per X11 /Reflection application).
2.Execute following command:

./go "-config=/jspm/forceMode=true -config=/jspm/deployVersionRule=updateAll"

  Note: On Windows OS quotation marks(" ") should be omitted. On windows execute command mentioned below.

           go -config=/jspm/forceMode=true -config=/jspm/deployVersionRule=updateAll

  This will start JSPM in force mode. 

  Force mode is supported since JSPM 7.0 SP9 / JSPM 7.1 SP2
