Getting dependencies from jar(war/ear)?

Question

Assuming I have a poor maintained project with all libs located in the CVS/Hard Drive and build running in pure Ant (without Ivy) or even compiled with IDE. Is there a tool that can look on the final product (jar/war/ear) and give me some report about it's dependencies, or even create a sample pom.xml/build.gradle?

Answer 1

What could help is the Advanced Search of Maven Central. With the 'By SHA-1 Checksum' you can select your jars. If that jar is available at Maven Central, you will get its coordinates. This would be a good start and hopefully will resolve most of your dependencies.
