代码的基本目录

1.${basedir} 表示工程目录

配置项默认值source code${basedir}/src/main/javaresources${basedir}/src/main/resourcesTests${basedir}/src/testComplied byte code${basedir}/targetdistributable JAR${basedir}/target/classes

2.环境配置 JAVA_HOME

操作系统输出Windows使用系统属性设置环境变量。M2_HOME=C:\Program Files\Apache Software Foundation\apache-maven-3.2.5 M2=%M2_HOME%\bin MAVEN_OPTS=-Xms256m -Xmx512mLinux打开命令终端设置环境变量。export M2_HOME=/usr/local/apache-maven/apache-maven-3.2.5 export M2=$M2_HOME/bin export MAVEN_OPTS=-Xms256m -Xmx512mMac打开命令终端设置环境变量。 export M2_HOME=/usr/local/apache-maven/apache-maven-3.2.5 export M2=$M2_HOME/bin export MAVEN_OPTS=-Xms256m -Xmx512m

POM.xml文件

在创建 POM 之前，我们首先确定工程组（groupId），及其名称（artifactId）和版本，在仓库中这些属性是工程的唯一标识。

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.companyname.project-group</groupId> <artifactId>projectname</artifactId> <version>1.0</version> </project> 查看 Super POM 默认配置的一个简单方法是执行以下命令：mvn help:effective-pom <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>12</groupId> <artifactId>12</artifactId>
