I've just installed the latest SonarQube 5.0.1 locally to try it out. The project I'm working with at the moment is hosted in Bazaar (bzr) source control. I looked at the SonarQube list of SCM plugins here:
http://docs.sonarqube.org/display/SONAR/Plugin+Library
Bazaar is not listed. Are there any workarounds or independent projects that I could use to get the scm history information from Bazaar into SonarQube? At this point I am just trying to get a sense of the value of the information to our project, rather than worry about a scalable production-ready solution.
There is currently (2015-04-09) no SCM plugin for Bazaar. If you wish to contribute one, feel free to take inspiration from e.g the SonarQube SCM integration plugin for Git.
