It might be related to groovy version. Try to use same version as in CI.

If you identify anything wrong or missing, update readme.
It currently says min version, but I guess it needs to be exact.

It is caused because of version issue only. I have just change my groovy version as same as ci (2.4.8) and report has successfully generated
