IDEA 修改配置文件的位置：
妳安裝軟件bin的同級目錄下：
eg:
````
# Use ${idea.home.path} macro to specify location relative to IDE installation home.
# Use ${xxx} where xxx is any Java property (including defined in previous lines of this file) to refer to its value.
# Note for Windows users: please make sure you're using forward slashes (e.g. c:/idea/system)
.#--------------------------------------------------------------------
-# Uncomment this option if you want to customize path to IDE config folder. Make sure you're using forward slashes.
#---------------------------------------------------------------------
idea.config.path=${user.home}/.IdeaIC/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}/.IdeaIC/system
