Build Failed: ant Remove, ant Install

Hi I am a bit new to this so I know really the very basic things.

My CI2260 folder is in a H Folder in my Home Directory.

This is what happens
Right when type ant clean in the CI2260 folder
------------------------------------------------------------------------
linux-phax:/home/rudu/H/CI2260 # ant clean
Buildfile: build.xml

clean:

ant remove
------------------------------------------------------------------------
linux-phax:/home/rudu/H/CI2260 # ant remove

.... I have attached my Build.xml and Build Properties

------------------------[SOMETHINGS YOU SHOULD KNOW]-------------------------
----->  Also you should know is that the Build and Build Properties and files from my university so I have not made them

---->  I have Apache2 Installed and Tomcat6

----> I followed the instructions of my tutor http://www.ubiubi.org/wrk/notes/SETUPS/ToolChainOpenSuse11.html
in which I found where he says :

To configure Tomcat and Ant
in /etc/ant.d create (as superuser) a file called catalina-ant5
in this file enter the text /tomcat/catalina-ant
check /etc/tomcat6/tomcat-users.xml looks like this and IS NOT COMMENTED OUT:

/tomcat/catalina-ant

"ant clean" did not work... but then I changed it to /tomcat6/catalina-ant
then ant clean did work...

----> type sudo /etc/init.d/tomcat restart to restart the server also i had to change it to: sudo /etc/init.d/tomcat6 restart to make this command work.
