              net.sf.antcontrib.property.PropertyCopy

public class PropertyCopy
extends AbstractPropertySetterTask

Task definition for the propertycopy task, which copies the value of a named property to another property. This is useful when you need to plug in the value of another property in order to get a property name and then want to get the value of that property name.

 Usage:

   Task declaration in the project:
   
     <taskdef name="propertycopy" classname="net.sf.antcontrib.property.PropertyCopy" />
   

   Call Syntax:
   
     <propertycopy name="propname" from="copyfrom" (silent="true|false")? />
   

   Attributes:
     name      --> The name of the property you wish to set with the value
     from      --> The name of the property you wish to copy the value from
     silent    --> Do you want to suppress the error if the "from" property
                   does not exist, and just not set the property "name".  Default
                   is false.

   Example:
     <property name="org" value="MyOrg" />
     <property name="org.MyOrg.DisplayName" value="My Organiziation" />
     <propertycopy name="displayName" from="org.${org}.DisplayName" />
     <echo message="${displayName}" />
