You can, if your IDE compiles the classes and invokes the annotation
processors along the way -- this will generate the microbenchmark list.
My IntelliJ IDEA does that perfectly well. Other IDEs may require
calling "mvn compile" before invoking the run.

Come again? You generally need a full compile session for the project
holding your benchmarks, as this will generate the microbenchmark list.
After that, you may invoke the JMH in any way you want.
