Kotlin 将ktor应用程序部署到Heroku后日志中出现错误

我已经用ktor构建了一个测试应用程序，它在我的本地主机上运行良好，但是当我将它上传到heroku并处理它时，它显示构建成功，但当我打开链接时，它显示应用程序错误

• 这是我的应用程序类：

• 这是我的文件：

*这是我的格拉德尔：

buildscript {
    repositories {
        jcenter()


    }
    
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

    }
}
apply plugin: 'java'
apply plugin: 'kotlin'
apply plugin: 'application'
group 'ktor.api.com'
version '1.0-SNAPSHOT'
sourceCompatibility = 1.8
mainClassName = "io.ktor.server.netty.EngineMain"

compileKotlin {
    kotlinOptions.jvmTarget = "1.8"
}
compileTestKotlin {
    kotlinOptions.jvmTarget = "1.8"
}

sourceSets {
    main.kotlin.srcDirs = main.java.srcDirs = ['src']
    test.kotlin.srcDirs = test.java.srcDirs = ['test']
    main.resources.srcDirs = ['resources']
    test.resources.srcDirs = ['testresources']
}

task stage {
    dependsOn installDist
    println "Running Stage"
}

repositories {
    mavenLocal()
    jcenter()
    maven { url 'https://kotlin.bintray.com/ktor' }
    maven { url 'https://kotlin.bintray.com/kotlin-js-wrappers' }
    maven { url "https://plugins.gradle.org/m2/" }
    maven {url 'https://jitpack.io'}
    maven {url 'https://github.com/psiegman/mvn-repo/raw/master/releases'}
    maven {url 'http://dl.bintray.com/kotlin/kotlinx.html'}
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"
    implementation "io.ktor:ktor-server-netty:$ktor_version"

    implementation "io.ktor:ktor-client-apache:$ktor_version"
    testImplementation "io.ktor:ktor-server-tests:$ktor_version"
}

• 这是连接到heroku帐户并获取日志后，我的cmd出现的错误

PS：我部署我的ktor应用程序的方式是简单地创建一个git并提交我的文件，然后在heroku网站内，我创建一个应用程序并连接到我的github并部署该应用程序，任何帮助都将不胜感激。谢谢各位。

我刚刚解决了同样的问题

“kotlinserver”是一个错误的名称，我在控制台中运行了gradlew stage并转到Procfile（build/install/…）中指定的路径来检查它 我认为正确的名称是项目（模块）名称

我也想提几件事

• 首先，

  application.conf

  文件中的

  ${PORT}

  将接收系统环境变量值，因此您不需要在应用程序模块函数中处理

  val PORT=system.getenv（“PORT”）？.toInt（）：23567

  。在

  application.conf

  中添加两行，例如下面的

  port=8080

  port=${？port}

  将端口设置为8080，然后设置为SystemEnv端口（如果存在）
• 第二，提醒一下，别忘了为你的应用程序运行

  heroku ps:scale web=1

  （你也可以在

  web=1

如果您想在heroku上部署ktor应用程序，请阅读关于ktor应用程序部署的中型博客

ktor {
    deployment {
        environment = development
         port = ${PORT}
    }
    application {
        modules = [ ktor.api.com.ApplicationKt.module ]
    }
}
