This article is about how to get started with maven quickly. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Basic knowledge

As mentioned in the maven tutorial, maven projects manage dependencies on projects through pom.xml files. In pom.xml, dependencies (that is, third-party jar packages) are managed through dependencies tags and their child tags dependency, as shown in the following figure, which introduces springboot framework and log4j dependencies.

Org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-logging org.springframework.boot spring-boot-starter-log4j2 org.springframework.boot spring-boot-starter-jdbc Mysql mysql-connector-java 5.1.34 org.springframework.boot spring-boot-devtools runtime true org.springframework.boot spring-boot-starter-test test

As you can see, maven's projects are managed by dependency tags, and each dependency tag contains some package information, through which maven can find the corresponding package in the repository and install it. Next, we will explain in detail how to do dependency updates by installing a dependency.

The first step is to search the maven warehouse for the packages you need.

Using Aliyun's warehouse, the editor can go to Aliyun's warehouse service page to find the search package function.

Aliyun Warehouse search package page: https://maven.aliyun.com/mvn/search.

Find the package you need and click to generate dependencies.

The second step is dependency import

In the previous step, you can get the dependency writing of the package you need, write it into the dependencies tag, and import the dependency into the project.

However, there is no way for the project to use the dependency right now, and there are two more steps that need to be taken:

Mvn clean description: clean up the temporary files produced by the project, usually the target directory under the module.

Mvn install description: install dependencies.

The two directives can be merged into mvn clean install-e-U, which clears the temporary files of the project and then forces updates, and displays detailed exceptions.

Easier ways to use maven

The above import-dependent method operates on the command line and is not so friendly to beginners. This shows the advantages of IDE and plug-ins. For example, if you use IDEA for maven dependency updates, IDEA will help you guide the package automatically as long as the corresponding dependency is written in the pom file. For example, if you use VSCode's maven plug-in, it encapsulates the common methods of maven and can be used directly.
