IDEA项目的依赖(pom.xml文件)导入问题及解决_Java

前言

idea新建项目和pom.xml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pom.xml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settings_aliyun.xml文件)来使用，我就是用这个方法才解决的😂😂
