how to use the jcoverage java tool by using ANT in eclipse - eclipse

Question

I wanna prepare jcoverage report for my unit tests by using ANT and eclipse. I'm using
Apache Ant(TM) version 1.8.3 compiled on February 26 2012
selenium-server-standalone-2.20.0
junit-4.8.1.jar
eclipse sdk 3.6.1
i tried as mentioned in this link here.
but i'm not able to succeed.please provide if any documents are available or make me clear how to prepare report.
my ant file:
<?xml version="1.0"?>

Answer 1

The error informs you that the javac compiler cannot find the junit jars. Although you specify the junit.class.path as the class path in the compiling ant target, that classpath contains references to the ${libs} property that is not defined anywhere in the build.xml
Also, you should move the property definitions (like lib.dir) before you use them (e.g. before the definition of jcoverage.path that references ${lib.dir})
Note: you can see the classpath used by either calling ant with the -verbose option or calling the <echo>${junit.class.path}</echo> task before the <javac> task
