It's normal to not bundle a logging file as your user may wish to configure this separately/externally. I have built a simple project with one main class and log4j in the resources folder and this works running in Netbeans.
不捆绑日志文件是正常的，因为您的用户可能希望单独/外部配置它。我在资源文件夹中构建了一个包含一个主类和 log4j 的简单项目，该项目在 Netbeans 中运行。

You can use the Maven Antrun Pluginto write an ant script which will execute during a lifecycle phase of maven.
您可以使用Maven Antrun 插件编写一个 ant 脚本，该脚本将在 Maven 的生命周期阶段执行。

简单地说你log4j.properties下src/main/resources/META-INF。

<targetPath>${project.build.directory}/</targetPath>
<directory>src/main/java</directory>
<includes>
<include>*.properties</include>
</includes>

If you place your log4j.properties file into
如果您将 log4j.properties 文件放入
src/main/resources/log4j.properties
Then during maven build it will get placed into correct location automatically See, this is a view of my jar file.
然后在 maven 构建过程中它会自动放置到正确的位置 看，这是我的 jar 文件的视图。
