java gradletomcatplugin:log4j:WARN找不到记录器的附加程序

Question

我已经配置了gradle tomcat插件，但是当我运行tomcatRun任务时，log4j会被激活。未找到src/main/resources文件夹中的xml配置文件：

log4j:WARN No appenders could be found for logger
...

在记录器的线程中，我可以使用

Thread.currentThread().getContextClassLoader().getResource("log4j.xml"); // project_root/build/resources/main/log4j.xml

这在理论上就是log4j加载文件的方式

如果我在Tomcat安装中部署war，我就不会有这个问题

运行任务的完整日志：

12:03:16: Executing task 'tomcatRun'...

> Task :processResources UP-TO-DATE
> Task :classes UP-TO-DATE

> Task :tomcatRun
Started Tomcat Server
The Server is running at http://localhost:8080/project_context

(this comes from a System.out.println() before trying to use the logger)
File : /C:/Users/MyUsername/IdeaProjects/project_name/build/resources/main/log4j.xml
