Configuring Eclipse Code Analysis

I have been using Eclipse Code Analysis for C++ for a little while. I have now tried applying it to an existing project and am having some problems getting rid of the noise.

Is there a way of excluding files from the analysis? I have found ways of turning off files for individual rules, but am looking for a global control.

Also, I want to be able to set up system headers to be inspected as required and as included so that the undefined variable count is cut down. Is 开发者_JS百科this possible?

The code compiles and runs fine at the moment so this tool is currently too sensitive.

I have alreadyfound some potential bugs using this tool and would like to tune it better. I am using Eclipse Indigo with Codan.

Actually, the feature you want is marked as future work. But, you can always try to create your checker, like it is explained here.
