Maven Build要求提供日志文件和（权限被拒绝）

Question

我有一个我从GitHub下载的开源Maven项目。该项目名为ElasticInbox（https://github.com/elasticinbox/elasticinbox.git）。

当我尝试构建项目时，我收到以下错误：

ERROR in ch.qos.logback.core.rolling.RollingFileAppender[FILE] - openFile(/var/log/elasticinbox/elasticinbox.log,true) call failed. java.io.FileNotFoundException: /var/log/elasticinbox/elasticinbox.log (Permission denied)

最初错误是找不到文件然后我通过终端手动创建了这个日志文件。据我了解，这不是正在执行的项目代码。它似乎是maven构建，抛出这个错误，我无法继续前进。

有人可以帮我解决这个问题吗？

Answer 1

因为不会与他人共享对文件位置的访问权限。因此，您将获得许可拒绝问题。

在logback.xml文件中，https://github.com/elasticinbox/elasticinbox/blob/master/config/logback.xml指定了日志文件的位置。尝试更改其用户目录的路径，它应该工作。

Answer 2

刚遇到完全相同的问题，您可以进行以下检查：

1. 确保path是正确的 - 以/为前缀意味着绝对;
2. 当前用户有权写入文件 - 用sudo ls -alh path_to_the_file检查，如果没有，则使用sudo chown -R user:user the_parent_folder_name进行更改;

我通过首先删除整个文件夹来修复它，然后创建一个具有适当所有者的新文件夹。
