我从 Git 克隆了项目，但是当我运行应用程序类时出现此错误。

【问题讨论】：

创建该路径的文件夹（/opt/apps/aggregator/api/logs）和文件（Duke-service.log），并提供对/opt/的文件夹和文件的写权限应用程序/聚合器/api/logs/Duke-service.log

标签： java spring-boot gradle build logback

【解决方案1】：

从日志看来，用户（通过它登录，例如 abhishek）没有创建目录 /opt/apps/aggregator/api/logs 的权限

所以首先要确保运行 Springboot 服务器的用户 (abhishek) 有创建目录的权限。

您可以通过在（/opt/、/opt/apps/ 和子目录如果它们已经存在）中执行 ls -ltra 来检查这一点

例如

-rw-r--r-- 1 raviy raviy 655 2019 年 2 月 25 日 .profile -rw-r--r-- 1 raviy raviy 220 2019 年 2 月 25 日 .bash_logout

这里 raviy 是所有者，如果您不是所有者，则更改权限（使用 sudo 或询问管理员）

chmod -R 777 /opt（应避免使用 777，它是运行程序的必要条件）

之后java应该能够创建目录
