Why do I still need maven?

Question

Java

Sorry for the stupid question)
I generated a maven webapp, imported it into ide. I'm running
: it doesn't work! I dug, poked around, and could not do anything through it.
As a result, I installed tomcat, added servletapi - it worked. but I could do it anyway. why do I still need maven?

Answer 1

I have several configurations configured in it - launching local development (cargo), uploading to a test server, uploading to production. As Fat Lorry rightly pointed out , it is too complicated for simple applications. But it becomes necessary when you want to integrate development into some corporate processes.

Answer 2

but I could do it anyway

To do nothing. Generally. Set it and forget it, regardless of the size and complexity of the application. In order not to resolve dependencies, pack and deploy the application as needed.
And for hallowords, all this is not necessary, yes.
