Changes by [unknown] in a Git plan
Problem
When a build is triggered by Repository Polling, it shows the message "Changes by [unknown]"
The following appears in the atlassian-bamboo.log
2019-01-18 19:41:01,040 ERROR [9-BAM::PlanExec:pool-15-thread-3] [GitChangeDetector] : Failed to extract changesets, will return a stub changeset.
java.lang.UnsupportedOperationException: JGit implementation does not support Git LFS repositories, please use native Git or mark your repository configuration as non-LFS

Check if the option Enable LFS support is enabled at Repository Settings > Advanced options.
Check if there is any Git capability configured at Administration > Build Resources > Server capabilities.
Cause
Git LFS option is enabled in that repository in Bamboo but JGit does not support it.
Resolution
- Install Git client in the machine hosting Bamboo and configure it at
Administration > Build Resources > Server capabilities.
OR - Disable the option Enable LFS support at
Administration > Build Resources > Linked repositories > reponame > Advanced optionsorPlan Configuration > Repositories > reponame > Advanced options.
