将自己的jar包发布到maven中央仓库(2025-08-29)

一、注册账号

https://central.sonatype.com/

二、新建命名空间

这里的命名空间需要填写github的用户名因为我的用户名是daimao0,所以命名空间填io.github.daimao0


这里要求你建一个名为ubuxfc5q7r的公共项目，先创建项目在点confrim

三、创建PUSH的账号密码

四、GPG准备

GPG 用于创建asc文件用于验证你的文件的正确性和安全性，我们直接去官网下载：

https://gnupg.org/download/index.html


用于我是arch-linux, linux系统一般自带gpg


输入两遍密码

这里的密钥发布到keyserver.ubuntu.com服务器上，把你的密钥替换掉 4CB3D9314CD5F1277582A11F4ADBA3851D627E38
备用地址:

keyserver.ubuntu.com 
keys.openpgp.org pgp.mit.edu

gpg --keyserver keyserver.ubuntu.com --send-keys 4CB3D9314CD5F1277582A11F4ADBA3851D627E38

验证密钥

如果出现了下面的内容说明发布成功

五、发布jar包

pom注意点

下面的配置必须都有

    <groupId>io.github.daimao0</groupId><artifactId>easy-http</artifactId><version>1.0.0</version><name>easy-http</name><description>A simple and easy-to-use HTTP client library for Java</description> <!-- 项目描述 --><url>https://github.com/daimao0/easy-http</url> <!-- 项目URL --><licenses><license><name>The Apache Software License, Version 2.0</name><url>http://www.apache.org/licenses/LICENSE-2.0.txt</url></license></licenses><developers><developer><!--   central发布插件 替换你自己的用户名和邮箱和pgp保持一致   --><name>daimao0</name><email>daimao2817@gmail.com</email></developer></developers><!--   scm 改成你自己的项目地址  --><scm><url>https://github.com/daimao0/easy-http</url><connection>scm:git:https://github.com/daimao0/easy-http.git</connection><developerConnection>scm:git:ssh://git@github.com/daimao0/easy-http.git</developerConnection></scm><profiles><profile><id>ossrh</id><build><plugins><!--   central发布插件    --><plugin><groupId>org.sonatype.central</groupId><artifactId>central-publishing-maven-plugin</artifactId><version>0.5.0</version><extensions>true</extensions><configuration><publishingServerId>ossrh</publishingServerId><tokenAuth>true</tokenAuth></configuration></plugin><!--   source源码插件 --><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-source-plugin</artifactId><version>3.3.1</version><executions><execution><id>attach-sources</id><goals><goal>jar-no-fork</goal></goals></execution></executions></plugin><!--   javadoc插件 --><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-javadoc-plugin</artifactId><version>3.10.0</version><executions><execution><id>attach-javadocs</id><goals><goal>jar</goal></goals></execution></executions></plugin><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-gpg-plugin</artifactId><version>3.2.5</version><executions><execution><id>sign-artifacts</id><phase>verify</phase><goals><goal>sign</goal></goals></execution></executions></plugin></plugins></build></profile></profiles>

然后就是执行

mvn clean deploy

点一下发布之后就等待就好了
