java - Maven: advantages of dependency management -

What are the main benefits of Maven Dependency Management? We have a Linux version on the server and every developer has to import that directory into that IDE and keep it up to date. Can Maven be simpler than that? Using per-project lib seems like a simple solution and it looks like a simple solution.

• Do you remember where you got it from foo.jar ?
• Are you sure that it is a legal source that no hacker tamper?
• Which version is foo.jar okay? Is this the original version or something that you have patched up?
• ?
• Need foo.jar a.jar for which y.jar for which z.jar < / Code> is needed ... do you really want to download it and manage it individually?
• You start another project. You now have the two Libs folder. Do you copy the jar or do you refer to them before the project?
• Your second project requires a different version of a jar How do you manage it?
• Imagine that you want to upgrade foo.jar in the next version. With Maven, this is a one-minute job. With a Lib folder, this means: searching the web, downloading a jar, putting it in the right place, possibly changing its name, removing the old version, adding a new version, making changes, cursing, similar to all dependencies Do you want to share your project with anyone else? They can not consider their versions of JARs - Maven is a simple and efficient mechanism for override dependency.
• Eventually, your legal department will come to ask you to guarantee that your project is clear from incompatible licenses. Maven can give you all the licenses of all your dependencies.
