无法看到资源文件夹

Question

我有一个Scala / Akka项目，我正在使用Maven构建。

我有一个存储常量和配置的文件：

/src/main/resources/reference.conf

但是，现在，我创建了一个父Maven模块和一个子Maven模块。

因此文件移至：

child-project/src/main/resources/reference.conf

现在，当我尝试使用reference.conf中的常量时，就像这样：

system.settings.config.getConfig("some-constant")

我收到此错误：

No configuration setting found for key 'some-constant'.

在查看此处No configuration setting found for key 'akka.version'后，我使用了maven-shade-plugin，但没有效果。

在主pom.xml我有这个可能相关的配置：

<build>
        <sourceDirectory>child-project/src/main/scala</sourceDirectory>
        <testSourceDirectory>child-project/src/test/scala</testSourceDirectory>

</build>

父模块中的pom.xml：

子模块中的pom.xml：

那么如何才能看到resources.conf

中声明的内容
