i've modified the the org.apache.tools.ant.taskdefs.Property class to support value overriding.
if the override attribute is present and set to true or yes, allows to
change the value of an existing project property (user properties are
not affected).
this functionality works with all the flavors of the property task
(value, file, etc.)
<property name="favorite.color" value="red" />
<property name="favorite.color" value="green" override="yes" />
attached you'll find the modified Property.java file.
regards.
