This week, I was tasked to create a development infrastructure with the following components: Subversion for Source Code Management, Trac for bugtracking, Hudson for Continuous Integration, Sonar for Quality Reporting, and Nexus, a Maven repository. I added 2 more components: a database in order to store data from each application in the same datastore, and a LDAP in order to authentify oneself in each application with the same credentials.
