Maven学习笔记1

1.搭建Maven环境

1.1检查jdk是否安装：

JAVA_HOME=D:\java\Jdk1.6

%JAVA_HOME%\bin

%JAVA_HOME%\jre\bin

 

java -version

java version "1.6.0_24"

Java(TM) SE Runtime Environment (build 1.6.0_24-b07)

Java HotSpot(TM) Client VM (build 19.1-b02, mixed mode, sharing)

 

1.2下载安装Maven，下载maven的zip文件，解压后并配置环境变量就可以了

MAVEN_HOME=D:\java\Maven

%MAVEN_HOME%\bin

http://maven.apache.org/

mvn -v

Apache Maven 3.0.4 (r1232337; 2012-01-17 16:44:56+0800)

Maven home: D:\Java\maven\apache-maven-3.0.4\bin\..

Java version: 1.6.0_24, vendor: Sun Microsystems Inc.

Java home: D:\Java\Jdk 1.6\jre

Default locale: zh_CN, platform encoding: GBK

OS name: "windows xp", version: "5.1", arch: "x86", family: "windows"

请按任意键继续. . .

注：当Maven由于某些原因(maven升级或原maven安装文件损坏)改变了安装文件的路径，重新配置maven的环境变量并且复制原Maven的配置(比如conf/settings.xml的全局配置)就ok了

 

1.3Maven优化

1.3.1配置MAVEN_OPTS环境变量(解决内存溢出、乱码问题)

-Xms128m -Xmx512m -Dfile.encoding=UTF-8

mvn -v

会出现这样的语句

Default locale: zh_CN, platform encoding: UTF-8

配置ok

1.3.2在Maven项目中配置 maven 插件

<!--maven plugn version-->

<properties>

<maven-compiler-plugin-version>2.5.1</maven-compiler-plugin-version>

<maven-clean-plugin-version>2.5</maven-clean-plugin-version>

<maven-resources-plugin-version>2.5</maven-resources-plugin-version>

<maven-war-plugin-version>2.3</maven-war-plugin-version>

</properties>

<!--清理插件-->

<plugin>

<groupId>org.apache.maven.plugins</groupId>

        <artifactId>maven-clean-plugin</artifactId>

        <version>${maven-clean-plugin-version}</version>

</plugin>

<!-- java文件编译class文件插件 -->

<plugin>

</configuration>

</plugin>

<!--war-->

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-war-plugin</artifactId>

<version>${maven-war-plugin-version}</version>

<configuration>

<!-- 指定文件,否则"非.java”文件将被忽略 -->

<packagingExcludes>WEB-INF/web.xml</packagingExcludes>

</configuration>

</plugin>
