前言
- 前面写过一篇把Jar包上传到GitHub仓库,有个弊端就是必须先声明
repository地址才能把jar包拉下来，这次直接把jar包上传到中央仓库,就没这个烦恼了，直接声明pom坐标即可。
准备
中央仓库
-
打开中央仓库 https://central.sonatype.com/ 注册帐号，建议直接使用GitHub登陆，
Namespace会自动验证好。
-
pom.xml的
groupId就写这个已验证的Namespace。 -
创建
token
-
配置到maven
settings.xml文件中
xml
...省略...
<servers>
<server>
<id>central</id>
<username>生成的Token用户名</username>
<password>生成的Token密码</password>
</server>
..省略...
</servers>
...省略... 生成 GPG 密钥
上传到中央仓库的二进制文件都必须经过签名，以证明它们没有被篡改
- 下载软件：Windows地址 https://www.gpg4win.org
- 生成密钥对
shell
gpg --full-generate-key密钥类型：
RSA and RSA密钥长度:
4096其余按自己情况填写
- 上传公钥
shell
#先查看 ID
gpg --list-keys --keyid-format LONG- 上传到公钥服务器( Key ID是
rsa4096/后面16个字符)
shell
gpg --keyserver keyserver.ubuntu.com --send-keys 你的KeyID项目配置
- 我以自己的项目https://github.com/1030907690/flink-sql-connector-elasticsearch8为例。
- pom.xml要配置项目的描述信息（根据自己的情况替换掉相应描述信息），还有插件。

</build>- 注意：每个类要有注释，否则执行deploy时会报错：
上传jar包
- 我将版本号改为
1.0.4 - 点击
deploy
- 中途会弹窗输入密钥密码。
- 上传成功后在中央仓库后台就能看到如下信息。
- 点击
Publish按钮后，稍侯再搜索便能查到此版本的pom坐标了。
其他
- 如果你有两台电脑，都想使用同一个密钥，可以使用
Kleopatra先备份私钥，然后另一台电脑再导入即可使用。
