Coordinates and repositories in maven

A build and coordinates

The build passes the coordinates as its unique identifier.

Coordinates are usually composed of the following three elements.

<groupId>com.cakin24.maven01</groupId>

<artifactId>maven01-model</artifactId>

<version>0.0.1SNAPSHOT</version>

 

Second warehouse

Used to manage project dependencies, warehouses are divided into two types: local warehouses and remote warehouses: local warehouses and remote warehouses.

If the dependency is not found in the local warehouse, it will go to the global central warehouse to find it. After finding it, it will be downloaded to the local warehouse. If not found, an error will be reported.

Global central warehouse address: https://repo.maven.apache.org/maven2
