apache-maven在Ideal中的配置

一、

*.lastUpdated
是EveryThing清理下载失败的文件

 二、

一定要记住，每次新建一个Maven时，都要在Settings中配置路径，不然默认在C盘，内存越来越大，电脑越卡。

 Sttings-->Build、Execution...-->Build Tools-->Maven

 图中三条蓝线：前两条能看懂，最后Local_repository是本地仓库，我们自己建一个文件夹m2/repository（最好和Idea目录放到一起）除系统盘外。因为仓库是我们运行项目时下载的一些插件等，会越来越大。

 

 

3、IDEA环境准备（配置来源 sou Hadoop：https://mvnrepository.com/search?q=hadoop）

{$MAVEN_HOME/conf/settings}

F:\m2\repository                 alimaven       aliyun maven       http://maven.aliyun.com/nexus/content/groups/public/       central                       jdk-1.8              true        1.8           1.8   1.8   1.8

 

3.1.0 Maven配置

3.1.1 Maven准备

所有的配置都会下载到我们配置的本地仓库中repository： G:\IntelliJ IDEA Community Edition 2016.3.1\bendicangku\repository     <dependencies>     <dependency>         <groupId>org.apache.hadoopgroupId>         <artifactId>hadoop-commonartifactId>         <version>2.8.4version>     dependency>     <dependency>         <groupId>org.apache.hadoopgroupId>         <artifactId>hadoop-commonartifactId>         <version>2.8.4version>     dependency>     <dependency>         <groupId>org.apache.hadoopgroupId>         <artifactId>hadoop-hdfsartifactId>         <version>2.8.4version>     dependency>     <dependency>         <groupId>org.apache.hadoopgroupId>         <artifactId>hadoop-clientartifactId>         <version>2.8.4version>     dependency>     <dependency>         <groupId>org.projectlombokgroupId>         <artifactId>lombokartifactId>         <version>1.16.10version>     dependency>     <dependency>         <groupId>log4jgroupId>         <artifactId>log4jartifactId>         <version>1.2.17version>     dependency>     <dependency>         <groupId>org.slf4jgroupId>         <artifactId>slf4j-apiartifactId>         <version>1.7.7version>     dependency>          <dependency>         <groupId>junitgroupId>         <artifactId>junitartifactId>         <version>4.12version>         <scope>testscope>     dependency> dependencies>
