ClassGraph is an uber-fast parallelized classpath and module scanner for Java, Scala, Kotlin, and other JVM languages. It inspects classes, annotations, and resources at runtime with zero dependencies and broad JDK/JPMS compatibility.
Use cases
- scan classpath for annotated classes
- find all classes implementing an interface at runtime
- discover resources in jars and modules
- build plugin systems via classpath discovery
- scan JPMS modules for classes
When to choose
- you need fast, parallelized classpath scanning on the JVM
- you want a dependency-free scanner supporting Java, Kotlin, and Scala
- you need JPMS/module-path support
When to avoid
- you only need simple reflection on known classes
- you work outside the JVM ecosystem
