- Consider a Matrix build of 2x3 (debug/release x 3-variants)
- add the doxygen generation build step "Generate documentation using Doxygen"
- add the doxygen publisher "Publish Doxygen"
- trigger a build
- see that each build-configuration does a doxygen run
- see that there's doxygen only published once on the "main index" of the matrix build
- run doxygen only once on the parent workspace of a matrix build and there fore publish only one doxygen documentation
- publsh all built doxygen documentations
- add a configuration filter for doxygen and publish all resulting documentations
