怎么把JAR发布到maven中央仓库

project   选择community support -open source....
issue    选择new project
summary   填写一些项目简短描述
description 填写项目的描述
group id   这个最重要了, 要与你的工程pom文件里的顶级group id 一致, 而且这个是不能乱填的, 一般来说, 是你自己的域名反写
Project URL 进入到你项目的url, 假如你的项目在github上, 先进到你的项目中, 然后复制地址栏上的地址填进去就可以
SCM url   同上, 但是这个url要填写你的git资源下载地址, 就是项目右侧的clone&download那个按钮弹出来的地址
Username(s) 用户名
Already Synced to Central 默认选NO就可以, 因为暂时我们还不需要同步到中央仓库

group id对应的域名, 会通过以下几种方式验证这个域名是不是你的

please comment on this ticket when you promoted your first release, thanks

$ gpg --gen-key
#按照提示输入信息, 在输入密码的时候, 如果嫌麻烦就直接摁回车就可以, 这样秘钥就没有密码保护了, 密码保护只有在你的私钥泄露的时候才有用, 其他时候没用

$ gpg --list-keys
#这个指令会显示你的秘钥环, 类似于下面这样
#---------------------------------
# pub  rsa4096 2018-09-25 [SC] 
#  EABB59A7BFXXXXXX46604F95ED1503AA8CDxxxx (这个才是秘钥ID)
# uid      [ 绝对 ] xxx (zhushi) 
# sub  rsa4096 2018-09-25 [E]

$ gpg --keyserver hkp://pool.sks-keyservers.net --send-keys 秘钥ID
#发送你的公钥到秘钥仓库, 以后你的jar会使用私钥签名, maven中央仓库会去几个指定的秘钥仓库去找公钥来验证这个签名, 如果不上传是不能通过审核的

$ gpg --keyserver hkp://pool.sks-keyservers.net --recv-keys 秘钥ID
#验证你的公钥是否上传成功, 如果返回结果是 **未改变, 那就是成功了
