I have a Parameter in jenkins job whose value is a windows file path.for example , consider the following parameter

LICENSE_FILE=C:\Softwares\abc.lic

after this i have used the Build action "Export Parameters to File " and i have configured this action to export parameters to a file which is of format .properties.

for example let the file name to which i exported parameters be "installer.properties"

after the build is done . if i verify the contents of the installer.properties file , the parameter LICENSE_FILE  has reflected in the file in the following format

 LICENSE_FILE=C\:\\Softwares
abc.lic

There is "\" after the colon ":" and there is an extra "\" for each "\" in the value of the parameter . 

Because of this issue i was not able to export the value i intended to the properties file
