Apache Cassandra is built using Apache Ant therefore the Sonargraph Workspace needs to be set up manually, i.e. the definition of modules and the location of source and class files. For systems built with Maven or that are represented by an Eclipse or IntelliJ Workspace, the Sonargraph Workspace can be set up automatically. For more information, see Chapter 6, Creating a System and Section 8.8, “ Managing the Workspace ” .
