• Create a maven project, named nexusdemo
  https://www.jianshu.com/p/042073b7710b
  Suppose you create project information as follows:

    <groupId>net.wanho.nexus</groupId>
    <artifactId>nexus-demo</artifactId>
    <version>1.0-SNAPSHOT</version>

• The modified nexusdemo pom.xml, add the following node in the project below:

    <distributionManagement>
        <repository>
            <id>releases</id>
            <url>http://localhost:8081/nexus/content/repositories/releases/</url>
        </repository>
        <snapshotRepository>
            <id>snapshots</id>
            <url>http://localhost:8081/nexus/content/repositories/snapshots/</url>
        </snapshotRepository>
    </distributionManagement>

• install nexusdemo project
  in C: \ Users \ zhangli.m2 \ repository \ net \ wanho \ nexus \ nexusdemo \ 1.0-SNAPSHOT path below the nexusdemo-1.0-SNAPSHOT jar package and a corresponding mounting pom
• deploy nexusdemo project
  in D: \ soft \ sonatype-work \ nexus \ storage \ snapshots \ net \ wanho \ nexus \ nexusdemo \ path with the 1.0-SNAPSHOT nexusdemo-1.0-SNAPSHOT jar and its corresponding packet pom

Download jar package from PW

• Create a maven project, named nexus-use-jar
• Add the following dependence in the project:

<dependency>
    <groupId>net.wanho.nexus</groupId>
    <artifactId>nexus-demo</artifactId>
    <version>1.0-SNAPSHOT</version>
</dependency>

At this time, the package is introduced into the jar no problem, because it comes from .m2;

• Modify pom.xml nexus-use-jar, adding the following at the project node:

   <repositories>
        <repository>
            <id>abc</id>
            <url>http://localhost:8081/nexus/content/groups/public</url>
            <releases>
                <enabled>true</enabled>
            </releases>
            <snapshots>
                <enabled>true</enabled>
            </snapshots>
        </repository>
    </repositories>
    <pluginRepositories>
        <pluginRepository>
            <id>abc</id>
            <url>http://localhost:8081/nexus/content/groups/public</url>
            <releases>
                <enabled>true</enabled>
            </releases>
        </pluginRepository>
    </pluginRepositories>

• The Apache Snapshots and other configuration applied to the same set of
  clicks save
  the following results
  added to the same group
• Delete the C: \ Users \ zhangli.m2 \ repository \ \ wanho \ nexus folder net
  this time, nexus-use-jar project is dependent error, but later reimport the project, just delete the jar package again downloaded to the C: \ Users \ zhangli.m2 \ repository \ net \ wanho \ nexus folder. Obviously we do not have to re-install, the jar package is automatically downloaded from the PW.
  These are the nexus PW maven jar package to build and upload and download process.
