The build.properties file contains the following contents..

appserver.home=D:/apache-tomcat-6.0.18
appserver.lib=${appserver.home}/lib
deploy.path=${appserver.home}/webapps

tomcat.manager.url=http://localhost:8080/manager
tomcat.manager.username=tomcat
tomcat.manager.password=s3cret

Still i'm having the same problem...
