Hi! cobertura:cobertura executes it's own lifecycle: instruments the classes, instrumented classes are saved to target/generated-classes/cobertura, and executes unit tests. Instrumented classes dump coverage data to target/conbertura/cobertura.ser. There are two things to understand:
1. When cobertura:cobertura is executed, dependencies are not instrumented. You have to have enabled instrumentation, see cobertura:instrument goal. This will produce jars with instrumented classes, so be careful not to distribute them. 2. Each module will write coverage data to it's own target/conbertura/cobertura.ser file. I think it's possible to configure instrumentation so that all jars write to the same cobertura.ser file, but I don't know whether it's normal, and I never tried that. When you have multiple cobertura.ser files, you can merge them with ant script and generate report from the merged file. Check build-configurator project [1], it does what you need. I used instructions from cobertura-maven-plugin to configure the build [2].
