My query is how to find git logs and the files changed due to a particular commit using a Java Program. Can any 1 help me in this.

Please See : This code is working fine in Ubuntu i.e. no Path problem still I am unable to get the files changed during a commit. It is give me a List as a null.

Solution

This bug was opened a long time ago and just fixed it. Please give it a try , use master branch please, and let me know if it works for you.
