java-class-enumerator | Simple code to dynamically discover Java classes

java-class-enumerator is a Java library. java-class-enumerator has no bugs, it has no vulnerabilities, it has build file available and it has low support. However java-class-enumerator has a Non-SPDX License. You can download it from GitHub.

Strictly speaking, it isn't possible to list the classes in a package. This is because a package is really nothing more than a namespace (eg com.epicapplications.foo.bar), and any jar-file in the classpath could potentially add classes into a package. Even worse, the classloader will load classes on demand, and part of the classpath might be on the other side of a network connection. It is possible to solve a more restrictive problem. eg, all classes in a JAR file, or all classes that a JAR file defines within a particular package. This is the more common scenario anyways. Unfortunately, there isn't any framework code to make this task easy. You have to scan the filesystem in a manner similar to how the ClassLoader would look for class definitions. There are a lot of samples on the web for class files in plain-old-directories. Most of us these days work with JAR files. To get things working with JAR files, try this simple library.
