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????????

导入xml文件:进入第二种方法的 maven 界面勾选右侧第一个override
按第一种方法重新导入一下即可
至此,sync出现绿√即导入项目依赖成功啦!
