What property needs to be set to change the branch value when using Git?

The property that needs to be set to change the branch value when using Git is Glide.source_control.default_branch. This property is crucial because it specifies which branch is considered the default branch for a git repository within the ServiceNow platform. By setting this value, you can establish what branch will be used for operations when no specific branch is indicated.

In the context of version control, the default branch typically serves as the main line of development. Therefore, setting this property directly impacts how changes are managed and integrated in the system. It determines the baseline from which features and fixes can be branched out and later merged back, facilitating organized workflow and collaboration in a development environment.

As for the other options, they may relate to functionalities within Git or ServiceNow but do not specifically pertain to changing the active branch value. They either control different aspects of branching or have specific purposes that do not directly affect the default branch setting.
