What tools do you use for managing dependencies in legacy Java projects?

Managing dependencies in legacy Java projects can be challenging, especially when they are not on modern build systems like Maven or Gradle. A new tool has emerged that resolves dependencies and generates a ZIP file containing the artifact along with all required transitive JARs. This tool is particularly useful for legacy Ant projects, offline environments, quick prototyping, and debugging. It doesn't require an account and keeps no record of dependency requests. What tools or strategies do you find effective for handling dependencies in older Java projects? Have you tried any similar tools?
