maven使用笔记

下载maven

http://maven.apache.org/download.cgi

安装java

sudo apt-get install default-jresudo apt-get install default-jdk#通过这个命令看到java安装路径sudo update-alternatives --config java/usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java#配置环境变量export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64export JRE_HOME=${JAVA_HOME}/jreexport CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/libexport PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH

配置maven路径

vim /etc/profileexport MAVEN_HOME=~/java/apache-maven-3.3.9export PATH=$PATH:$MAVEN_HOME/binsource /etc/profile

验证Maven的安装

mvn -versionApache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-11T00:41:47+08:00)Maven home: /home/chenjianhua/java/apache-maven-3.3.9Java version: 1.8.0_91, vendor: Oracle CorporationJava home: /usr/lib/jvm/java-8-openjdk-amd64/jreDefault locale: zh_CN, platform encoding: UTF-8OS name: "linux", version: "4.4.0-23-generic", arch: "amd64", family: "unix"

Maven的生命周期主要有编译、测试、打包、部署。

修改${MAVEN_HOME}/conf/settings.xml配置文件

• 保存仓库的路径

<!-- localRepository | The path to the local repository maven will use to store artifacts. | | Default: ${user.home}/.m2/repository<localRepository>/path/to/local/repo</localRepository>-->#查看下载后的仓库ls ~/.m2/repository

• 修改远程镜像仓库地址

<mirrors>  <mirror>    <id>alimaven</id>    <name>aliyun maven</name>    <url>http://maven.aliyun.com/nexus/content/groups/public/</url>    <mirrorOf>central</mirrorOf>          </mirror></mirrors>

通过maven创建简单程序

`group Id`：com.fenby (包名)`artifact Id`fenby （项目名）mvn archetype:generate -DgroupId=com.fenby -DartifactId=fenby -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

在这个新建的项目中，我们可以看到有个pom.xml文件,pom是对象模型,有pom.xml说明是个maven项目

<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/maven-v4_0_0.xsd">  <modelVersion>4.0.0</modelVersion>  <groupId>com.fenby</groupId>  <artifactId>fenby</artifactId>  <packaging>jar</packaging>  <version>1.0-SNAPSHOT</version>  <name>fenby</name>  <url>http://maven.apache.org</url>  <dependencies>    <dependency>      <groupId>junit</groupId>      <artifactId>junit</artifactId>      <version>3.8.1</version>      <scope>test</scope>    </dependency>  </dependencies></project>

添加依赖包

#在`<dependencies>`标签中加入<dependency>  <groupId>Mysql</groupId>  <artifactId>mysql-connector-java</artifactId>  <version>5.1.30</version></dependency>

项目目录结构

目录 约定的用途 src/main/java 项目的java源代码 src/main/resources 项目的资源，比如property文件 src/test/java/ 项目测试类，比如Junit代码 src/main/resources 测试使用的资源

maven常用命令

#创建Maven的普通java项目mvn archetype:generate -DgrouId=packageName -DartifactId=projectName#创建Maven的Web项目：mvn archetype:generate -DgroupId=packageName -DartifactId=webappName -DarchetypeArtifactId=maven-archetype-webapp#打印整个依赖树mvn dependency:tree#查看有效的pom.xml信息mvn help:effective-pom#将项目转化为Eclipse项目mvn eclipse:eclipse#编译源代码mvn compile#运行测试mvn test#打包项目mvn package#只打jar包mvn jar:jar  #清除产生的中间文件mvn clean#在本地repository中安装jarmvn install#调用 Jetty 插件的 Run 目标在 Jetty Servlet 容器中启动 web 应用mvn jetty:run     #下载源代码mvn dependency:sources -DdownloadSources=true -DdownloadJavadocs=true#生成eclipse的配置文件mvn eclipse:eclipse#查看帮助信息mvn help:help

保留Mybatis Mapper配置文件

<resources>    <resource>        <directory>src/main/java/com/github/chenjianhua    </directory>    <targetPath>com/github/chenjianhua</targetPath>    <includes>        <include>**/*.xml</include>    </includes>    <filtering>false</filtering>    </resource></resources>

添加eclipse的maven插件

Windows –> Preference –> Maven –> Installations –>Add

设置maven配置文件路径

Windows –> Preference –> Maven –> User Settings
