自建Maven项目如何发布到Sonatype和Central中央仓库中（三）_maven central repository sonatype

自建Maven项目如何发布到Sonatype和Central中西仓库中（一）

1.配置Maven库的全局Setting.xml文件

	<server>
		<id>sonatype</id>
		<username>sonatype的账号</username>
		<password>sonatype的密码</password>
	</server>

2.配置Maven项目根POM文件，增加发布到中央仓库的profile

    <profiles>
        <profile>
            <id>sonatype-release</id>
            <activation>
                <activeByDefault>true</activeByDefault>
            </activation>

                </repository>
            </distributionManagement>
        </profile>
    </profiles>

3.发布项目到中央仓库

 mvn clean deploy -Psonatype-release

4.需要注意的点

a.根POM文件，必须配置 name、url、description

b.必须生成source和javadoc。在maven plugin中配置响应的插件，见上文
