/usr/bin/git log --format=%H --ancestry-path 96a0f365073698bf84f34bf61cd232a577bc65e6..8f4dd668df1178275c41c8a3475fe13404b9a759
Fails with the following message:
1
fatal: unrecognized argument: --ancestry-path
Cause
/usr/bin/git is pointing to an old Git installation, e.g., 1.7.1. Versions prior to 1.7.9 are not supported according to the Bamboo 5.5 Supported Platforms.
Resolution
Upgrade Git to at least 1.7.9, in which version the --ancestry-path parameter was added. Please note that this might not automatically update /usr/bin/git to make it point to this new installation, so please also check if, after the installation, /usr/bin/git is indeed pointing to 1.7.9, by running:
1
/usr/bin/git --version
Also, please check if your Git capability is pointing to /usr/bin/git.
