First of all: what is maven?
Maven is the project's construction tool, written in Java, so it is used in conjunction with Java.
Function: Create projects, write frameworks, write projects, quickly create projects, and must have a network, manage jar packages, have plug-in support, and automatic packaging and other functions.
Where can I download such a good thing?
Of course it is here.
After downloading, we need to configure the system environment variables.
In the same way, press the win key on the keyboard, enter and edit the system environment variable
click open
Click on Environment Variables
Click the path in the system variable and double-click.
Put the bin file path in.
Then we open the downloaded maven and go in to take a look.
Introduce these folders,
bin: the executable file of the software
boot: Put the external required jar packages and plug-ins
conf: configuration file
lib: The jar package for personal use, don't touch it
reop: It is a folder between me, which is equivalent to a private warehouse
Then the second step: set up maven
Open the conf folder and open settings.xml
The first step is to create a repo private warehouse folder.
Then wrap the path to your reop with <localRepository> tags.
Step two:
Go to this URL and copy this passage
Then put it in the middle of <mirrors></mirrors>
Like this, then maven is set up.
Then let's try to create it in the idea. Open our modus operandi.
There are two creation methods, let’s demonstrate them one by one.
Then right-click add framework support, assuming to be a web page, select web application
Then click pom, pom.xml in the upper left corner
Add the jar package you want in the pom
Click m in the upper right corner to add this package.
When he downloads it, he will not report an error.
The red is gone.
There are functions that come with maven here.
Then we click on the settings in the file
Find this and modify it to the maven you downloaded
ok, this is the end
