Process finished with exit code 1

解决方案： 1.更改window 登录的用户名为英文。（此方法自行百度吧，就不做讲解了）

2.更改idea生成文件的默认路径：

  help->Edit Custom VM Options...  中添加  -Djava.io.tmpdir=E:\resource\idea\Temp

注意： 一定要先创建对应的文件夹 

 

 

既然都更改了临时文件的位置，不如其他的默认路径一起更改了吧：

注意：更改下面的默认路径配置之后，之前的idea插件将全部丢失！！！

1.找到idea安装目录下面的bin文件下的idea.properties

（E:\tools\IntelliJ IDEA 2020.2\bin\idea.properties）

找到：idea.system.path=${user.home}/.IntelliJIdea/system

idea.plugins.path=${idea.config.path}/plugins

更改即可。
