intellij创建maven项目遇到的问题

现在才开始用maven也是汗。。刚上手就在IDE里碰到不少问题
1.勾选create from archetype时，创建maven项目一直卡在running C://users/xxx/.m2/archetypetemp，卡了很久（并没有等到它创建成功。。。感觉太久了）
网上搜到的解决方法：
1）在创建项目时在下图Properties中点击右边+

弹出如下显示框，输入图中参数

之后开始下一步，速度还可以
2）干脆不用intellij的archetype，不要勾选create from archetype，具体创建过程见下链接http://www.voidcn.com/blog/SJZYLC/article/p-4971448.html

1. 创建项目后发现intellij右侧的maven project选项卡中的maven项目报错，plugin目录下缺少jar包，在file->setting->Build,Deployment,Execution->Maven选项卡中，更改maven使用的目录，最好使用自己下载的最新版（强烈不建议使用intellij自带的maven，简直慢到死），配置如下图
   

改掉maven目录后，一定要记得把下面的user setting file和local repository改掉，改成对应maven目录下的settingfile和repo，setting file目录为%MAVEN_HOME%/conf/settings.xml，不要用原来默认的在C盘的maven配置，这些都是和intell自带maven对应的

比较坑的是如果不改掉User setting file 和 local repository的话，无法在项目目录中导入pom.xml中的依赖（在project的library中什么都没有），而且在pom.xml开头的project上会报错，显示cannot reconnect, inspect maven model for resolution problems，打开日志文件（help->show log in explorer)，报错如下
