Idea's .jar package maven manages the project

        Let me talk about the background first: the landlord is a chicken, just started working, originally used eclipse to develop the project, and recently transferred the project to Idea development. I just came into contact with it, and I am not familiar with the shortcut keys of Idea, dug or something, the development is a mess. Fortunately, there is a great god with me, thank God in advance. Brush a wave of 66666666666666666666666666666666666666666666666666666666666666666666666666666!

        No bb, let’s get to the topic: Using maven to manage JAR packages under Idea is simple and rude:

        1. Find your pom.xml

        2. Right-click to find Maven, select Reimport (you made a mistake, Phuket Island), and then wait for it to be ok;

        3. Then check if your code is up to date! ! ! If not, update it, do it all over again, wow, that's it! ! !
