JDepChk is a dependency checker for Java virtual machine (JVM) class files. It can be used for any code that runs on the JVM. Highlights:

• Specify components and dependencies using high-level rules.
• Transitive dependencies (if B extends A, users of B inherit A).
• Regular expression matchers and include/exclude lists.
• Check for accesses to entire classes or individual members.
• Multiple rule sets loadable from different files.
• Use annotations, on package-info.java, and on restricted elements.
• Very fast. Based on a stripped-down version of ASM's class reader.
• Processes class files one by one (unlike some other such tools).
• Has an Eclipse plugin with smart error highlighting.

JDepChk was directly inspired by Macker, but is a lot faster and easier to use in typical scenarios (due to component-oriented rules).
