rootDir property
RootDir is where in the repository the build runs, for a project that is not at the repository root. Omitted means the root.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
String? rootDir;
