[rules-users] Getting Null pointer exception for applying change set

[Rana]

I reads my changeSet file but it is again not able to read the drl file that
is specified in the changeSet.xml.
My STS (Eclipse) and Workspace is in D: drive, so that files are also in D:
drive.


Caused by: java.lang.IllegalArgumentException:
'D:/Venkat/workspace/pi-affiliate-drools-rule-engine/bin/AndroGel.drl' path
