当我们在使用Intellij IDEA进行开发的时候，经常会遇到Cannot Resolve Symbol X的错误提示，出现这样的提示一般是以由于maven项目遇到这类问题基本上是两方面的原因，类对应的依赖没有加载进来、编译器自身的设置和缓存问题引起的，我们可以按下面方法进行操作。

问题一： 1、检查项目的pom文件，是否必要的依赖都写清楚了； 2、是否使用自己的私有库，  release Private  Repository http://xxxxxx   

 

 release PrivateRepository http://xxxxxxx   pom文件中有这样的就是使用自身的私有库，库的用户名密码有没有写清楚，一般在maven程序目录的settings.xml文件中设置，在标签下设置，类似这样：   nexus admin 

aaaaaaaaaa   3、依赖正确的添加后，我们检查本地的类有没有下载下来，通常下载路径为“C:\Users\Administrator\.m2\repository”查看该路径中有没有相应的jar包，如果没有的话，就在编译器中打开”Maven Projects “标签，先进行clean一下，在执行install，这里与在命令行下执行是一样的效果，如图：



若在该路径中可以看到这个包，那么则属于第二类问题。

问题二：

1、 File - Project Structure - Project SDK，查看是否选择SDK，重选一个本地的自己安装的jdk； 2、编译器中的maven是否成功设置，File - Settings - 搜索maven，Maven home directory，设置为自己安装的maven路径；  3、如果还是报错找不到，试试右侧Maven Projects - Report ，刷新样式的按钮，清除下编译器的缓存即可解决。

以上便是小编给大家介绍的Intellij IDEA Cannot Resolve Symbol 的处理方法！
