Question

I have about 30-40 Jars that are being used by my application. Since the application is old and many have worked on it before me, therefore i want to figure out, if there has been any customization on them or not.

currently i am trying to find all the jars from the available versions and then downloading them. then i am planning to run a diff-merge on them to find out the difference.

I think there should be an alternative way to this. please tell. some can be found out just by looking at the JAR name or Manifest File. but what about others?

please help.

Answer 1

You could calculate a hash code such as MD5. If both jars have the same MD5 hash code, it’s very likely the content is the same as well.

Otherwise if you have a good test coverage you could go for a try and error approach:

• Mavenize your project
• Run the tests
