Description: Allows plug-ins to define arbitrary Ant tasks for use
by the Ant infrastructure. The standard Ant infrastructure
allows for the addition of arbitrary tasks.
Unfortunately, it is unlikely that the Ant Core plug-in
would have the classes required by these tasks on its
classpath (or that of any of its prerequisites).
To address this, clients should define an extension
which plugs into this extension-point and maps a
task name onto a class. The Ant plug-in can then
request that the declaring plug-in load the specified class.
<!ELEMENT extension (antTask*)>
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 antTask EMPTY>
name CDATA #REQUIRED
uri CDATA #IMPLIED
class CDATA #REQUIRED
library CDATA #REQUIRED
headless (true | false)
eclipseRuntime (true | false) >
- name - name of the task to be defined
- uri - The uri that this definition should live in. Only used if using Ant newer than 1.6.
- class - the fully qualified name of a Java class implementing
the task. Generally this class must be a subclass of
- library - a path relative to the plug-in install location
for the library containing the task.
- headless - indicates whether this task is suitable for use in a "headless" Ant environment. If running headless and the attribute is "false",
the task will not be loaded or defined. As well, the plugin class loader will not be added as a parent classloader to the Ant classloader.
The implied value is true, when not specified.
- eclipseRuntime - indicates whether this task requires an Eclipse runtime (i.e. must be run in the same VM as Eclipse). The implied value is true, when not specified.
Examples: The following is an example of an Ant tasks extension point:
<antTask name="coolTask" class="com.example.CoolTask" library="lib/antSupport.jar"/>
In the above example the
antSupport.jar must be created using an Ant project builder. For more information about creating project builders and how they work, please refer to the following help topics: Contributing tasks and types, Ant buildfiles as project builders and Creating a project builder Ant buildfile
Supplied Implementation: The platform itself supplies a number of tasks including
eclipse.incrementalBuild and eclipse.refreshLocal.
