            </configuration>
        </plugin>
    </plugins>
</build>

5, 修改 Maven settings.xml
添加

<settings>
  <servers>
    <server>
      <id>ossrh</id>
      <username>your-jira-id</username>
      <password>your-jira-pwd</password>
    </server>
  </servers>
</settings>

6，生成密钥，这个一定要，不然不能发布。
下载地址：https://www.gpg4win.org/download.html
图形界面生成一个,右击证书在服务器上发布。
7，发布

mvn clean deploy

没有mvn的吧，去apache下载一个，设置好path，然后去代码目录执行上面的命令发布。

set path=%path%;C:\Users\tanmingxin\Downloads\apache-maven-3.8.6-bin\apache-maven-3.8.6\bin

8,去这个地址https://s01.oss.sonatype.org/#stagingRepositories登录点击上面的Release
然后会收到一封邮件通知，Issue中也会收到Comment
Central sync is activated for net.eudu. After you successfully release, your component will be available to the public on Central https://repo1.maven.org/maven2/, typically within 30 minutes, though updates to https://search.maven.org can take up to four hours.
