Maven的日常

强烈建议把 Maven 的 settings.xml 文件同时放在：%USER_HOME%/.m2/settings.xml 和${maven.home}/conf/settings.xml 两个地方。避免使用终端的时候默认去调用用户目录下的。

更多只使用阿里云仓库的setting.xml配置、使用nexus私有仓库+阿里云仓库的settings.xml配置。（自己日常是用阿里云镜像。）

【profile】为了解决不同环境所需的不同变量、配置等问题。

profile 一般可以在三个地方：settings.xml（仓库），pom.xml（dev和prod），profiles.xml（这个不常用）

在 settings.xml 上，一般大家用来做仓库的选择，设置全局的 profile，一个是 nexus 仓库，一个是 aliyun 仓库，默认激活的是 nexus 仓库。（activeProfiles）

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"

          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

在 pom.xml 中，一般用来激活环境配置(打包的时候，默认是 dev 模式，打包 src/main/env/dev 下的配置文件，如果选择 product 则打包 src/main/env/product 下的配置文件)

<profiles>

    <profile>

        <id>dev</id>

        <properties>

            <package.environment>dev</package.environment>

        </properties>

        <activation>

            <activeByDefault>true</activeByDefault>

        </activation>

        </build>

    </profile>

    <profile>

        <id>product</id>
