Sign maven central repository

注册Namespace

请务必以github进行登入，这样就可以有免费的namespace可以用

原文
If you do not see this pop-up AND you signed up with GitHub, then Sonatype was able to grant you permissions to the namespace associated with your GitHub identity automatically. As part of your GitHub subscription, GitHub provides you with a github.io domain that reflects your username and allows you to publish GitHub Pages under that domain. Because of this, Sonatype can, in most cases, automatically verify and provision publishing access to a namespace that looks like io.github..

Deployment config

找到namespace

务必确保资料一致

<groupId>io.github.internetms52</groupId>
<artifactId>object-pool</artifactId>
<version>0.1.3</version>
<name>object-pool</name>
<packaging>jar</packaging>
<url>https://github.com/internetms52/object-pool-maven-lib</url>
<description>This is a library that implements an Object Pool, and it supports nested object creation as well as constructor specification.</description>

Generate User Token

View Account > Generate User Token
完成后就会取得settings.xml所需的资讯

指定server(settings.xml)

<settings>
    <servers>
        <server>
            <id>central</id>
            <username>XXXXXX</username>
            <password>YYYYYY</password>
        </server>
    </servers>
</settings>

指定maven central repository server设定(pom.xml)

<plugin>
    <groupId>org.sonatype.central</groupId>
    <artifactId>central-publishing-maven-plugin</artifactId>
    <version>0.5.0</version>
    <extensions>true</extensions>
    <configuration>
        <publishingServerId>central</publishingServerId>
    </configuration>
</plugin>

Java doc

使用Maven Plugin产生Java Doc

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-javadoc-plugin</artifactId>
    <version>3.2.0</version>
    <executions>
        <execution>
            <id>attach-javadocs</id>
            <goals>
                <goal>jar</goal>
            </goals>
        </execution>
    </executions>
</plugin>

GPG

产生GPG Key Pair

sudo apt-get install gnupg
gpg --full-generate-key
gpg --list-keys

GPG签名plugin

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-gpg-plugin</artifactId>
    <version>3.0.1</version>
    <executions>
        <execution>
            <id>sign-artifacts</id>
            <phase>verify</phase>
            <goals>
                <goal>sign</goal>
            </goals>
            <configuration>
                <gpgArguments>
                    <arg>--pinentry-mode</arg>
                    <arg>loopback</arg>
                </gpgArguments>
            </configuration>
        </execution>
    </executions>
</plugin>

上传GPG公钥

GPG的公钥server有两个比较有名的

• pgp.mit.edu
• keyserver.ubuntu.com

gpg --keyserver hkp://pgp.mit.edu --send-keys F1BD06AB06C36BD5EB53B6E8710DEC40549547D2
gpg: sending key 710DEC40549547D2 to hkp://pgp.mit.edu

gpg --keyserver hkp://keyserver.ubuntu.com --send-keys F1BD06AB06C36BD5EB53B6E8710DEC40549547D2
gpg: sending key 710DEC40549547D2 to hkp://keyserver.ubuntu.com
