Java Code does NOT compile.

[contractormarketplace]

The following instructions to get a build on the java source does NOT seem to be accurate.

Install tomcat. You can get it from Tomcat site.
Download the ChargeBee's java library.
Copy the library jar to java/webapp/WEB-INF/lib in this repo.
Compile the classes using ant -f build/build.xml -Dtomcat.home=

I downloaded the ChargeBee's java libary and placed the following files in the java/webapp/WEB-INF/lib directory
chargebee-java-2.8.5.jar
chargebee-java-2.8.5-sources.jar
chargebee-java-2.8.5-javadoc.jar

When I run the ant command, I get the attached error which indicates something is wrong with the libraries included.
