1.问题

今天在vscode 学习如何使用 plantUML生成图片的时候，发生错误

java.util.concurrent.ExecutionException: java.net.UnknownHostException: raw.githubusercontent.com

issue raw.githubusercontent.com java.util.concurrent.ExecutionException: java.net.UnknownHostException: raw.githubusercontent.com

原因在于无法访问 raw.githubusercontent.com

2.修改Hosts解决

Vscode 打开C:\Windows\System32\drivers\etc\Hosts文件添加一行
