## org.apache.tools.ant.taskdefs
Class CallTarget

    java.lang.Object
      org.apache.tools.ant.ProjectComponent
          org.apache.tools.ant.Task
              org.apache.tools.ant.taskdefs.CallTarget

All Implemented Interfaces:
  java.lang.Cloneable

    public class CallTarget

extends Task

Call another target in the same project.

        <target name="foo">
          <antcall target="bar">
            <param name="property1" value="aaaaa" />
            <param name="foo" value="baz" />
           </antcall>
        </target>

        <target name="bar" depends="init">
          <echo message="prop is ${property1} ${foo}" />
        </target>

This only works as expected if neither property1 nor foo are defined in the project itself.

Since:
  Ant 1.2
