how use ant it???

the if/else tasks not part of standard ant (requires 3rd party jar)

conditional execution of targets performed follows:

<project name="demo" default="process">      <property name="sourcefile" location="c:\test\application\services\test"/>      <available property="sourcefile.is.a.file" file="${sourcefile}" type="file"/>     <available property="sourcefile.is.a.dir" file="${sourcefile}" type="dir"/>      <target name="process" depends="process-file,process-dir"/>      <target name="process-dir" if="sourcefile.is.a.dir">         <echo message="${sourcefile} dir"/>     </target>      <target name="process-file" if="sourcefile.is.a.file">         <echo message="${sourcefile} file"/>     </target>  </project>
