Ant-contrib Tasks: Propertycopy

# Propertycopy

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.

## Parameters

Attribute | Description | Required
--- | --- | ---
property | The name of the property to set. | Yes.
override | If the property is already set, should we change it's value. Can be `true` or `false` | No. Defaults to `false`
name Deprecated | The name of the property to set. | No. Use the `property` attribute instead
from | The name of the property you wish to copy the value from. | Yes.
silent | Do you want to suppress the error if the "from" property does not exist, and just not set the property "name". | No, default is "false".

## Example

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