IDEA项⽬的依赖（l⽂件）导⼊问题及解决前⾔
IDEA新建项⽬和l⽂件被修改时，右下⾓都会出现 Maven projects need to be imported（项⽬需要导⼊依赖）
如下，点击 Import Changes导⼊后，有时会⼀直处于加载中或导⼊失败
解决⽅法
第⼀种⽅法：
右击l⽂件，选择Maven中的Reimport重新导⼊项⽬依赖，⼀般这种⽅法都解决不了上⾯的问题，可直接看下⾯的⽅法
第⼆种⽅法：
点击 File 选择 Settings… 直接搜索 Maven，在搜索结果中 Maven home directory：默认为Bundled(Maven 3)，点击选择IDEA⾃带的Maven，再点击应⽤–>OK，重新导⼊(第⼀种⽅法)即可
第三种⽅法：
若第⼆种⽅法还不能解决项⽬的依赖导⼊问题，则需要使⽤国内的Maven类库，IDEA的Maven类库默认都是使⽤国外的，⼀些地区由于墙的原因加载会很慢或者加载不了，此时可以导⼊阿⾥云的 Maven 类库(⼀个l⽂件)来使⽤，我就是⽤这个⽅法才解决的
