Targets are collections of project components (but not other targets) that are
assigned a unique name within their project. A target generally performs a specific task
-- or calls other targets that perform specific tasks -- and therefore a target is a bit
function (but a target has no return value).
depend on other targets. For example, if target A
depends on a target B, then when target A is called to be executed, target B will be
executed first. Phing automatically resolves these dependencies. You cannot have
circular references like: "target A depends on target B that depends on target A".
The following code snippet shows an example of the use of targets.
<target name="othertask" depends="buildpage" description="Whatever"> <!-- Task calls here --> <target> <target name="buildpage" description="Some description"> <!-- Task calls here --> <target>
When Phing is asked to execute the
othertask target, it will see
the dependency and execute
buildpage first. Notice that the
dependency task can be defined after the dependent task.
