Environment variables not passed to Artifactory

im trying to pass property value from file with EnvInject to Artifactory.

1. im using post step to inject the properties
2. using Deployment properties to pass the property to Artifactory
i'm printing the value in post step build and see the correct value
but in artifactory i see the value as parameter e,g ${propertyName} and not the value.

using Artifactory pro 3.4.2
using Artifactory plugin 2.2.5
using jenkins 1.572
using ENVInject plugin 1.9.0

please advice
