This article mainly explains "maven coordinates and warehouse introduction and configuration," interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let Xiaobian take you to learn "maven coordinates and warehouse introduction and configuration"!

1. What is maven warehouse?

1.1 Warehouse and component

A repository refers to storing all maven project shared artifacts in one place.

A component can be a plug-in, a jar package, or our own build output.

1.2 Warehouse classification

1.3 The process of finding artifacts in a warehouse?

2. What are maven coordinates (dependencies)?

2.1 Coordinates (Dependency) Definition

Coordinates are unique locations that identify artifacts in the warehouse.

2.2 How do I add coordinates (dependencies)?

For example: Add a dependency procedure for spring-test.jar

1). Open maven's central repository: search.maven.org/

2). Search Warehouse:

http://search.maven.org/#artifactdetails|org.springframework|spring-test|3.2.16.RELEASE|jar

3). Configure maven pom, add a set of dependencies, copy the above coordinate address:

XML code

1. 2. 3. org.springframework 4. spring-test 5. 3.2.16.RELEASE 6. 7. 3. How to publish a project to a repository

mvn install: publish to local repository

mvn deploy : publish to remote repository

Publish local items to local repository: (local repository address: D:\mavenRepository3\com\sohu\train\maven-02\1.0-SNAPSHORT\maven-02-1.0-SNAPSHORT.jar)
