when I run Ant in cmd it is showing me error of build.xml not exist while I have build.xml file in my project folder - ant

Question

I am a selenium user trying to generate xslt reports using Ant, but when I run Ant in cmd it is showing me error of build.xml not exist while I have build.xml file in my project folder.
I am using eclispe juno on windows 7 and and kept the build.xml file under the project.
I have java JDK1.7 on my machine and I have already set the environment variables(Java and ant both) as per instructions given on apache.org
Ant version is apache-ant-1.9.1
I have imported all necessary jar files (selenium + maven +saxon + all required for xslt report through ant) in my project in eclipse.
When I am trying to run ant through cmd it is showing me this error:-
BUILD FAILED
D:\Projects\Project\Selenium\Workspace\build.xml:70: Compile failed; see the compiler error output for details.
Below is my build.xml file:-

Thanks you all for your great help, I have resolved that error ..
It was related to the path of the jar files , I provided incorrect path to the jars.
This was line 70 : -
<javac debug="true" destdir="${test.dest}" srcdir="${test.src}"
target="1.7" classpath="${test.classpath}">
this is related to the path to the jars and in the top line of my file I did provided this path - D:\All jars , while all required jars was not in this folder, now I updated the jar folder and it is working fine now.
