When we are trying to get the Changeset information from groovy we are getting this exception:

java.lang.UnsupportedOperationException: getAffectedFiles() is not implemented by RTC
at hudson.scm.ChangeLogSet$Entry.getAffectedFiles(ChangeLogSet.java:242)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

at java.lang.reflect.Method.invoke(Method.java:498)
at org.codehaus.groovy.reflection.CachedMethod.invoke(CachedMethod.java:93)

We will need that the plugin implements this method in order to obtain the files of a ChangeSet.
