The Views plugin in SonarQube allows users to treat projects as directories, aggregating them into arbitrary collections and providing a consolidated view of an application's quality. This enables users to group multiple projects together and get a dashboard for the aggregate application, rather than relying on spreadsheets or manual aggregation. The plugin also provides intuitive interfaces for creating views based on various criteria, such as language, measures, or regular expressions, and allows for drilling down into component-level details. By adding the Views plugin to SonarQube, users can gain a more holistic view of their application's quality, unencumbered by traditional project boundaries.
