public class ClassFinder extends Object
Find classes under the specified package via some classpath entry Usage:
   // find classes under `me.sunlan` package via classpath entry(directory) `D:/_APPS/git_apps/java8-labs/out/production/classes/`
   ClassFinder.find(URI.create("file:/D:/_APPS/git_apps/java8-labs/out/production/classes/"), "me/sunlan")
   // find classes under `groovy.lang` package via classpath entry(jar file) `D:/_DEV/Groovy/groovy-3.0.1/lib/groovy-3.0.1.jar`
   ClassFinder.find(URI.create("file:/D:/_DEV/Groovy/groovy-3.0.1/lib/groovy-3.0.1.jar"), "groovy/lang")
   // find classes under `java.lang` package via classpath entry(jrt)
   ClassFinder.find(URI.create("jrt:/modules/java.base/"), "java/lang")
   // find classes under the sub-packages too, e.g. we can get GroovydocHolder via the following code
   ClassFinder.find(URI.create("file:/D:/_DEV/Groovy/groovy-3.0.1/lib/groovy-3.0.1.jar"), "groovy/lang", true)
