一、预置环境

基于Centos7预置环境（均可以使用我的一键安装脚本）

java 1.8
maven 3.6.3（maven3.8以上不再支持http，弃用）
gpg 2.0+（Centos7内置）

需要去System Dashboard - Sonatype JIRA创建一个Issue，使用的域名还要验证是否真实持有。

创建成功之后，如图所示，此时就可以进行jar包部署了。

二、发布

2.1 创建密钥

安装生成随机字节的工具，用于密钥生成

1 2	yum -y install rng-tools rngd -r /dev/urandom

着手生成密钥

1	gpg --gen-key

将密钥发布到密钥服务器

1	gpg --keyserver keyserver.ubuntu.com --send-keys 你的密钥

去掉空格，建议直接浏览器console
“B515 0A97 DB5A C076 3E6A 0BC2 D241 590E E91B 2A73”.replaceAll(/\s+/g,””);

2.2 配置Maven

在maven的settings.xml里面添加

可以which mvn来获取到路径，进而找到/usr/local/maven/conf/settings.xml

<server>
    <id>ossrh</id>
    <username>sonatype用户名</username>
    <password>sonatype密码</password>
</server>

2.3 配置pom

以我自己的pom为例，主要是将官方提供的plugin都cv了过来。

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

2.4 部署

运行

1	mvn clean deploy -DskipTests=true

使用上面这个命令的前提是，需要在maven的settings.xml里面，额外添加

<settings>
  <profiles>
    <profile>
      <id>ossrh</id>
      <activation>
        <activeByDefault>true</activeByDefault>
      </activation>
      <properties>
        <gpg.executable>gpg2</gpg.executable>
        <gpg.passphrase>the_pass_phrase</gpg.passphrase>
      </properties>
    </profile>
  </profiles>
</settings>
