下载Maven和Nexus
apache-maven-3.3.9
nexus-2.12.0-01

解压nexus,进入目录
D:\nexus-2.12.0-01-bundle\nexus-2.12.0-01\bin>
安装服务
D:\nexus-2.12.0-01-bundle\nexus-2.12.0-01\bin>nexus.bat install
启动服务
D:\nexus-2.12.0-01-bundle\nexus-2.12.0-01\bin>nexus.bat start
wrapper | Starting the nexus service...
wrapper | Waiting to start...

访问如下地址测试Nexus私服是否安装成功
http://127.0.0.1:8081/nexus

管理员的默认密码是
admin/admin123

同步Maven中央库的索引文件

修改配置,下载远程的索引

然后Repair索引.

可以看到正在执行的RepairIndex的任务.

在项目的pom.xml文件中,配置私服地址

<repositories>
<repository>
<id>nexus</id>
<name>Team Nexus Repository</name>
<url>http://localhost:8081/nexus/content/groups/public</url>
</repository>
</repositories>
<pluginRepositories>
<pluginRepository>
<id>nexus</id>
<name>Team Nexus Repository</name>
<url>http://localhost:8081/nexus/content/groups/public</url>
</pluginRepository>
</pluginRepositories>

或者拷贝maven/conf/settings.xml文件到用户家目录的.m2文件夹下
修改该文件

<mirrors>
<mirror>
<id>central</id>
<mirrorOf>*</mirrorOf>
<name>central-mirror</name>
<url>http://localhost:8081/nexus/content/groups/public/</url>
</mirror>
</mirrors>

如果需要从本地发布jar包到私服
需要先在私服上创建一个账号

设置用户,注意权限

然后在项目的pom中加入如下配置

<distributionManagement>
<repository>
<id>deployment</id>
<name>Nexus Release Repository</name>
<url>http://127.0.0.1:8081/nexus/content/repositories/releases</url>
</repository>
<snapshotRepository>
<id>deployment</id>
<name>Nexus Snapshot Repository</name>
<url>http://127.0.0.1:8081/nexus/content/repositories/snapshots</url>
</snapshotRepository>
</distributionManagement>

然后修改家目录.m2文件下的settings.xml文件

<servers>
<server>
<id>deployment</id>
<username>dev</username>
<password>123456</password>
</server>
</servers>

标红的ID需要一致.

这时候运行如下命令
E:\workspace\test>mvn clean deploy
就可以将jar包直接发布在私服了.
