1. Maven介绍

Maven这个单词来自于意第绪语（犹太语），意为知识的积累，最初在Jakata Turbine项目中用来简化构建过程。Maven主要是一个针对Java的项目管理和构建自动化工具。Maven主要处理软件构建的两个方面：1、描述软件是如何构建的，即项目构建；2、描述软件的依赖，即依赖管理。

2. Maven安装

下载地址：https://maven.apache.org/download.cgi，解压之后找到Readme.txt按照说明安装即可。也可以按照Maven官网https://maven.apache.org/install.html安装。
作者是在Mac上使用brew install maven命令安装的。

安装成功之后，可以运行mvn -v命令来查看：

# 查看java版本
$ java -version
java version "1.8.0_91"
Java(TM) SE Runtime Environment (build 1.8.0_91-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.91-b14, mixed mode)

# 查看mvn版本，确认安装成功
$ mvn -v/-version
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-11T00:41:47+08:00)
Maven home: /usr/***/Cellar/maven/3.3.9/libexec
Java version: 1.8.0_91, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.8.0_91.jdk/Contents/Home/jre
Default locale: zh_CN, platform encoding: UTF-8
OS name: "mac os x", version: "10.11.6", arch: "x86_64", family: "mac"

注：Maven安装之前要确保你的系统中已经安装了JDK，可用java -version查看。

3. Maven目录结构

Maven是一个项目管理和构建自动化工具。Maven使用惯例优于配置的原则。Maven项目的目录结构如下：

目录 目的
${basedir} 存放 pom.xml和所有的子目录
${basedir}/src/main/java 项目的 java源代码
${basedir}/src/main/resources 项目的资源，比如说 property文件
${basedir}/src/test/java 项目的测试类，比如说 JUnit代码
${basedir}/src/test/resources 测试使用的资源
${basedir}/target 项目输出目录

maven项目编译的classes文件会放在${basedir}/target/classes目录下，打包的文件会放在${basedir}/target目录下。

4. Maven命令

测试mvn命令的项目为Spring Boot项目，项目创建参考我的文章：Spring Boot 2.0.0参考手册_中英文对照_Part II_11-12

4.1 mvn compile 编译项目，编译的内容在target目录（默认）

在使用mvn package进行编译、打包时，Maven会执行src/test/java中的JUnit测试用例，有时为了跳过测试，会使用参数-DskipTests和-Dmaven.test.skip=true，这两个参数的主要区别是：-DskipTests，不执行测试用例，但编译测试用例类生成相应的class文件至target/test-classes下。-Dmaven.test.skip=true，不执行测试用例，也不编译测试用例类。

5. Maven settings.xml

settings.xml是Maven最重要的配置文件，它通常位于两个位置：

  • Maven安装的主目录： $MAVEN_HOME/conf/settings.xml

  • 用户主目录： $USER_HOME/.m2/settings.xml

第一个setting.xml称为全局配置文件，第二个称为用户配置。如果两个文件同时存在，它们的内容将会合并，用户配置将会覆盖全局配置。

下面的内容翻译自Maven安装时的settings.xml文件：

      这是一个可以用许多方式激活的配置文件列表，在这里可以修改构建过程。settings.xml中提供的配置信息是用来提供本地特定机器路径和仓库位置的，
      这允许在本地环境中进行构建工作。例如，你有一个集成测试插件，假设为cactus，它需要知道Tomcat的安装地址，你可以在这提供一个变量，在构建过程中配置cactus插件时这个变量可以被间接引用。正如上面所提到的，可以通过许多方式来激活配置文件，一种方式是通过文档中（settings.xml）中的activeProfiles部分来激活，后面会进行讨论。另一种方式本质上是依赖系统属性的检测，通过匹配属性中的一个特定值或检测其是否存在。配置文件也可以通过JDK版本前缀激活，当在JDK 1.4.2_07版本上执行构建时，值1.4可以激活一个配置文件。最后，配置文件列表可以直接在命令行中指定。
      注意：对于在settings.xml文件中定义的配置文件，你只能指定工件仓库，插件仓库，自由形式的属性作为POM文件中插件配置的变量。
  -->
  <profiles>
    <!-- 
        指定构建过程的一系列介绍，通过上面描述的一种或多种机制来激活。对于继承，可以通过<activatedProfiles/>或命令行来激活配置文件，配置文件必须有一个唯一的ID。
        配置文件识别的最佳实践是在配置文件中使用一致的命名约定。例如'env-dev', 'env-test', 'env-production', 'user-jdcasey', 'user-brett'等等。这样可以更直观的理解引入的配置文件要实现什么，尤其是在调试时只有一系列配置文件的id的情况下。
        这个配置文件例子使用JDK版本来触发激活，并提供JDK特定的仓库。
