We are using Repository git now. We should use this option ("Build Condition : If changes found in referenced repositories") now because It's inefficient to build even if there are no changes in the repository.
I've visited the link below to use this feature, but I can't understand how to use the option with only the description there. Is there a sample node I can refer to? Please tell us how to use the function in detail.

options
1) Build Condition : If changes found in referenced repositories
2) Build Condition : If changes found in referenced repositories or last build failed
