Extending Team Concert 3.0

Hi

We used the RTC2.0 JAVA API's(without any issue) to fetch the files from the RTC workspace.

Now we have migrated to the RTC 3.0 but we are facing the below issue for fetching the file from RTC worksapce:

BUILD FAILED

Please let me know, if any one has any information about the changes in the RTC 3.0 JAVA API's.
