url property
URL is the clone URL a git app builds from, stored as sent once the build path's allowlist accepted it (validateRepoURL). It is also what a landed push is MATCHED against, so a push to any other repo never builds this app.
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? url;
