This article introduces the relevant knowledge of "dependencyManagement Analysis of maven". In the operation of actual cases, many people will encounter such a dilemma. Then let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

When you use maven to build a project, you will often see the following code in the pom file of parent:

Org.springframework.boot spring-boot 2.0.1.RELEASE org.springframework.boot spring-boot-test 2.0.1.RELEASE org.springframework.boot spring-boot-test-autoconfigure 2.0.1.RELEASE

So what's the difference with?

It is used to introduce jar directly and needs to be actually imported into classpath.

It is equivalent to version management of dependencies and does not download the required dependencies directly. It's just a version of the reference record. Its main purpose is to unify references to jar (multiple module). Therefore, this tag is usually in parent.

So what does it have to do with it?

When using introduced dependencies, you don't have to set them. At this point, start from looking for the corresponding dependency, and if it exists, download the corresponding version dependency directly. If not, an error will be reported and the setting will be prompted.

If the version number is set, the corresponding version jar is downloaded and dependency management is ignored.
