idea更改缓存路径

• idea的默认缓存路径是在C:\Users\Administrator\.IntelliJIdeaxxxxx，后面会越来越大；持续占用C盘空间；还是换到其他盘存储好点。
• 打开idea的安装目录找到bin/idea.properties文件,打开修改四个配置即可

#---------------------------------------------------------------------
idea.config.path=F:/ideaCaches/.IntelliJIdea2017.2/config

#---------------------------------------------------------------------
# Uncomment this option if you want to customize path to IDE system folder. Make sure you're using forward slashes.
#---------------------------------------------------------------------
idea.system.path=F:/ideaCaches/.IntelliJIdea2017.2/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=F:/ideaCaches/.IntelliJIdea2017.2/plugins

#---------------------------------------------------------------------
# Uncomment this option if you want to customize path to IDE logs folder. Make sure you're using forward slashes.
#---------------------------------------------------------------------
idea.log.path=F:/ideaCaches/.IntelliJIdea2017.2/log

• 之前的数据也可以平滑的迁移过来（比如idea的各种插件之类的,放到对应目录即可）。
