修改IDEA的缓存目录

intellij IDEA在第一次启动时，会在$\{user.home\}目录下建立以.IntelliJIdea开头的文件夹，用来存放IDEA的配置信息、插件和缓存信息。

随着工具使用时间越多，这个文件夹会越来越大。如果用户目录和系统盘在一个分区，那系统盘分区可用空间就会变小，系统重装时，这个目录还会被删除。

于是我们需要将此目录修改到其他分区，修改很简单，如下：

在IDEA安装目录的bin文件夹中找到idea.properties文件，我们需要修改里面的几项内容：

> \#---------------------------------------------------------------------  
> \# Uncomment this option if you want to customize path to IDE config folder. Make sure you're using forward slashes.  
> \#---------------------------------------------------------------------  
> \# idea.config.path=$\{user.home\}/.IntelliJIdea/config
> 
> \#---------------------------------------------------------------------  
> \# Uncomment this option if you want to customize path to IDE system folder. Make sure you're using forward slashes.  
> \#---------------------------------------------------------------------  
> \# idea.system.path=$\{user.home\}/.IntelliJIdea/system
> 
> \#---------------------------------------------------------------------  
> \# Uncomment this option if you want to customize path to user installed plugins folder. Make sure you're using forward slashes.  
> \#---------------------------------------------------------------------  
> \# idea.plugins.path=$\{idea.config.path\}/plugins
> 
> \#---------------------------------------------------------------------  
> \# Uncomment this option if you want to customize path to IDE logs folder. Make sure you're using forward slashes.  
> \#---------------------------------------------------------------------  
> \# idea.log.path=$\{idea.system.path\}/log

将idea.config.path和idea.system.path里面的$\{user.home\}改成将自己想存放的位置，我这里修改为D:/Program Files/JAVA/JetBrains，如下是修改后的结果：

> \#---------------------------------------------------------------------  
> \# Uncomment this option if you want to customize path to IDE config folder. Make sure you're using forward slashes.  
> \#---------------------------------------------------------------------  
> \# idea.config.path=$\{user.home\}/.IntelliJIdea/config  
> idea.config.path=D:/Program Files/JAVA/JetBrains/.IntelliJIdea/config
> 
> \#---------------------------------------------------------------------  
> \# Uncomment this option if you want to customize path to IDE system folder. Make sure you're using forward slashes.  
> \#---------------------------------------------------------------------  
> \# idea.system.path=$\{user.home\}/.IntelliJIdea/system  
> idea.system.path=D:/Program Files/JAVA/JetBrains/.IntelliJIdea/system
> 
> \#---------------------------------------------------------------------  
> \# Uncomment this option if you want to customize path to user installed plugins folder. Make sure you're using forward slashes.  
> \#---------------------------------------------------------------------  
> \# idea.plugins.path=$\{idea.config.path\}/plugins
> 
> \#---------------------------------------------------------------------  
> \# Uncomment this option if you want to customize path to IDE logs folder. Make sure you're using forward slashes.  
> \#---------------------------------------------------------------------  
> \# idea.log.path=$\{idea.system.path\}/log

** 注意：**一定要将配置项前面的注释符（\#）去掉，否则不生效。

接下来，重启IDEA工具就可以了。
