Create a new custom warehouse for private servers

Click Create repository, and select the type as maven2(hosted)

Enter the warehouse name private-release (custom), and select Release in the Version policy column, indicating that the storage dependency of this warehouse is an officially released component, and then select Allow redeploy in the Deployment policy column to allow deployment and update on private servers s component.
After clicking Create repository, you can see the custom warehouse in the warehouse list, and we will add a snapshot warehouse in the same way, just adjust it to Snapshot in the Version policy column. Creation of a snapshot repository

Add roles and users

add role

Add user

Click Create local user, fill in the user name, password and other required information, and associate with the role we created earlier, click Create local user to save, and the creation is successful.

Use Maven private server

Modify the server configuration file

On the server, open /data/nexus-3.25.1-04/system/setting.xml (vim setting.xml)

cd nexus-3.25.1-04/system
vim settings.xml

Adding true here can upload the version with SHAPSHOT, that is to say, it can be uploaded to the snapshot type library. If not added, the SHAPSHOT suffix can only be removed in the idea, otherwise an error will be reported.

Modify the local maven configuration file

Under the label in the local maven configuration file, add the account password and ID configuration for connecting to the private server as follows

<server>
        <id>buba-release</id>
        <username>yjt</username>
        <password>123456</password>
    </server>
    <server>
        <id>buba-snapshot</id>
        <username>yjt</username>
        <password>123456</password>
    </server>

Modify the POM file in idea

Add the following configuration to the POM file in Idea (the url here can be automatically copied through the cpoy button on the warehouse page on the Nexus background)

<distributionManagement>
        <repository>
            <id>buba-release</id>
            <name>buba-release</name>
            <url>http://192.168.216.135:8081/repository/buba-release/</url>
        </repository>

        <snapshotRepository>
            <id>buba-snapshot</id>
            <name>buba-snapshot</name>
            <url>http://192.168.216.135:8081/repository/buba-snapshot/</url>
        </snapshotRepository>
</distributionManagement>

Up to now, we have basically completed the configuration. Execute the deployment command mvn clean deploy or use the deployment plug-in of the IDE to publish. When BUILD SUCCESS appears on the console, it means the release is successful.

At this point, you can view the jar package we released on the warehouse page on the Nexus background
