I went through http://docs.codehaus.org/display/SONAR/Developing+Plugins , but unfortunately it does not give detailed steps. Can someone help me understand how I need to call a code checker that uses ANTLR to parse code files and then capture the output in Sonar How can I start supporting XPATH-based rules for my Sonar code analysis tool like this is done for Java / Javascript?
A good starting point is to view the code for existing plugins: http://github.com/sonarqubecommunity
I suggest you use the dev sonar mailing list: dev at sonar dot codehaus dot org. The development of the Sonar plugin cannot simply be covered by a "conductor" ...
