SonarCloud has added support for mono-repositories on Bitbucket Cloud, allowing users to configure multiple quality gates per project, receive individualized results, and access project-labeled messages. This feature enables developers to approach code quality and security at the project level, increasing accuracy and visibility in their development strategy. To set up a monorepo in SonarCloud, users can either import an existing repository or convert standard projects into a monorepo configuration, adding additional project keys as needed. With this new support, developers can leverage SonarCloud's feedback at the right level for their individual projects, improving overall code quality and security outcomes.
