How to find annotated methods in a given package?

Question

I have a simple marker annotation for methods (similar to the first example in Item 35 in Effective Java (2nd ed)):

/**
 * Marker annotation for met

You should probably take a look at the open source Reflections library. With it you can easily achieve what you want with few lines of code:

Reflections reflections = new Reflections( 
    new ConfigurationBuilder().setUrls( 
    ClasspathHelper.forPackage( "com.acme.installer" ) ).setScanners(
    new MethodAnnotationsScanner() ) );
Set methods = reflections.getMethodsAnnotatedWith(InstallerMethod.class);
