How to create a Groovy JAR file for SoapUI using Eclipse

"no such Property - com - for class customScripts...." - hmmmm

Does this mean that "com" has to be added as a Property to my class? Like "log", "context", "testCase" and "testSuite" are Properties and are included in my constructor? How do I add the com property, since the location from where I am calling this particular TearDown() method doesn't have a "com" Property?

Somehow, I should be able to tell my custom scripts that com is a valid Property, and I should be able to use com.?? in my scripts.
