Ant Properties

###### Identifier:

org.eclipse.ant.core.antProperties

###### Since:

3.0

###### Description:

Allows plug-ins to define Ant properties for use in Ant build files.

###### Configuration Markup:

<!ELEMENT extension (antProperty*)>

<!ATTLIST extension

point CDATA #REQUIRED

id CDATA #IMPLIED

name CDATA #IMPLIED>

- point - a fully qualified identifier of the target extension point
- id - an optional identifier of the extension instance
- name - an optional name of the extension instance

<!ELEMENT antProperty EMPTY>

<!ATTLIST antProperty

name CDATA #REQUIRED

value CDATA #IMPLIED

class CDATA #IMPLIED

headless (true | false)

eclipseRuntime (true | false) >

- name - The name of the property.
- value - The value of the property. If a value is provided here, the "class" attribute is ignored.
- class - If there is no 'value' attribute provided, this class is called to return the dynamic value for the Ant property. If null is returned, the value is not set.
- headless - indicates whether this property is suitable for use in a "headless" Ant environment. If running headless and the attribute is "false", the property will not be set and any specified `org.eclipse.ant.core.IAntPropertyProvider` will not be instantiated. The implied value is true, when not specified.
- eclipseRuntime - indicates whether this property should only be considered when run in the same VM as Eclipse. The implied value is true, when not specified.

###### Examples:

The following is an example of an Ant properties extension point:

       <extension point="org.eclipse.ant.core.antProperties">
          <antProperty name="eclipse.home"
               class="org.eclipse.ant.internal.core.AntPropertyValueProvider"/>
          <antProperty name="eclipse.running"
               value="true"/>
       </extension>

###### API Information:

The class named in the `class` property must implement the `org.eclipse.ant.core.IAntPropertyProvider` interface.

###### Supplied Implementation:

The platform uses this mechanism to set the Ant property eclipse.home to the Eclipse installation directory and to set the eclipse.running property.
