A few months ago, in order to use Hudson as CI for your C++/CMake/CppUnit projects you had to do quite a lot of shell scripting. By now the situation has very much improved as some very useful plugins came into existence. To cover the situation described in my previous post you can now use a combination of the CMake plugin and the CppUnit plugin.
With these extensions Hudson gets more and more useful for C/C++ developers. Yet another new plugin that supports this trend is the CCCC Plugin which uses the CCCC tool to generate trend reports for various software metrics including cyclomatic complexity.
