Ktor 0.9.3 导入其他配置文件抛出异常

Question

在 Ktor 0.9.3 应用程序中，我想为不同的环境使用不同的 .conf 文件，我扩展了一个主要的 .conf 文件。但是，我收到以下异常：

Exception in thread "main" com.typesafe.config.ConfigException$NotResolved: called valueType() on value with unresolved substitutions, need to Config#resolve() first, see API docs
    at com.typesafe.config.impl.ConfigDelayedMerge.valueType(ConfigDelayedMerge.java:46)
    at com.typesafe.config.impl.SimpleConfig.hasPath(SimpleConfig.java:96)
    at io.ktor.config.HoconApplicationConfigKt.tryGetString(HoconApplicationConfig.kt:33)

    at io.ktor.server.netty.DevelopmentEngine.main(DevelopmentEngine.kt:13)
    at ApplicationKt.main(application.kt:24)

这是我的 application.conf 文件：

ktor {
    deployment {
        port = 8080
        port = ${?PORT}
        watch = [ website ]
    }
    application {
        modules = [ ApplicationKt.module ]
    }
}

ui {
  hotreload {
    enabled = false
    path-prefix = "http://localhost:3000"
  }
}

以及我想使用的扩展：

include "application.conf"

ui.hotreload.enabled = true

知道哪里出了问题以及如何解决吗？

根据我在 Ktor's GitHub page, this is a known bug for which a PR fixing it 上打开的问题已经合并，因此应该在下一个版本中修复。事实上，它在版本 0.9.4-alpha-2

中按预期工作
