First, properties passed on the command line are read-only, so you can't
change them. Your first property task will fail if you pass customer on
the command line.
The way around that is to use a naming convention to distinguish
properties from the command line from the properties that you'll use in
the rest of the script. For example, use customer for the property on
the command line, and customer.value everywhere else.
So, you could write:
<property name="customer.value" value="FladDevelopment" />
<property name="customer.value" value="${string::to-lower(customer)}"
if="${customer != ''}" />
though I think you're better off with
<property name="customer.value" value="fladdevelopment" />
<property name="customer.value" value="${string::to-lower(customer)}"
if="${property::exists('customer')}" />
because the user could write something like -D:customer=''
