There is a package on the Nexus private server but cannot be downloaded Could not find artifact

Problem Description

I encountered this problem during the process of learning Nexus, and then Nexus was installed on the local computer.

The project error is as follows:

There is nothing wrong with maven configuration

There is indeed the jar package in nexus, which is strange.

problem solved

<mirror>In fact, there is a problem with the configuration. Many tutorials on the Internet let you configure tags in maven . In fact, it is not possible to configure him at all. Configure the following configuration in maven's setting.xml to download:

<servers>
  <!-- 这是配置访问私有仓库的用户名密码 -->
  <server>
    <!-- id标签可以随便填，只需要在servers中唯一即可，后面很多地方会使用该id -->
    <id>self-maven</id>
    <username>deplyment</username>
    <password>deplyment123</password>
  </server>
</servers>
