Tài liệu Ant: The Definitive Guide phần 2

Content
0 n nested <property> elements (all)
Passes a property to the new build process.
Example Usage
Invoke the default target on util_buildfile.xml in the current directory:
<ant antfile=util_buildfile.xml/>
Invoke the clean target on build.xml in the gui directory:
<ant dir=gui target=clean/>
Invoke another buildfile, passing a new value for the builddir property. The value is
explicitly set to utiloutput even if the property was defined elsewhere in the calling
buildfile:
<ant antfile=util_buildfile.xml>
<property name=builddir value=utiloutput/>
</ant>

See the property task for allowable attributes on nested <property> elements.
antcall all
org.apache.tools.ant.taskdefs.CallTarget
Invokes a target in the current buildfile. Properties are passed to the new target using nested
<param> elements. An investigation of the Ant source code reveals that antcall instantiates
and calls the ant task using the current buildfile. This means that a new project instance is
created and properties work the same as they do for ant.
