Sir, I'm working on a maven project currently. I face some problem
integrating JMH on my existing project. So I have got a few question. Hope
you'll answer...

1. How to integrate JMH in existing maven project?
2. How to Benchmark a method that takes parameters from another method (See
below scenario)?

I need to compute the execution time of apply(Migratable m) method for each
time it is being called.

Note that Migratable is an interface.

*******************************Scenario********************************

class Test {

public void applyAll() {
....................
....................
Collection<migratable> applicableUpdates =
SomeOtherClass.getApplicableUpdates(int
index);
doUpdate(applicableUpdates);

}

@Benchmark
public void apply(Migratable m) {
....................
....................
}

private void doUpdate(Collection<migratable> applicableUpdates) throws
Exception {
for (Migratable m : applicableUpdates) {
try {

apply(m);

} catch (Exception e) {
logger.error("Falid to apply migration {}" + m, e);
throw e;
}
}
}
}
