Kotlin 找不到Heroku任务阶段

我正试图将我的项目部署到Heroku上，我遵循了，但没有一个对我有效

我的gradle看起来像这样：

apply plugin: 'kotlin'
apply plugin: 'application'
apply plugin: 'kotlinx-serialization'

version '0.0.1'
mainClassName = "io.ktor.server.jetty.EngineMain"

task stage(dependsOn: ['clean', 'installDist'])

repositories {
    mavenLocal()
    jcenter()
    maven { url 'https://kotlin.bintray.com/ktor' }
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"

    //Log
    implementation "ch.qos.logback:logback-classic:$logback_version"

    //KTor core
    implementation "io.ktor:ktor-server-jetty:$ktor_version"
    implementation "io.ktor:ktor-server-core:$ktor_version"
    implementation "io.ktor:ktor-client-core:$ktor_version"
...

我已经用

web:./build/install/my-ws/bin/my-ws创建了
Procfile

我在终端上运行了
/gradlew stage
，效果很好

但是当我按下heroku master键时，仍然会出现错误

remote:        Task 'stage' not found in root project 'my-ws'.
remote:        



确保阶段任务位于根项目中。如果不是，则声明一个依赖于子项目的任务：

task stage(dependsOn: [':subproject:stage'])

只需转到build.gradle文件并粘贴以下代码

tasks.create("stage") {
    dependsOn("installDist")
}

同样的结果，如果您想在heroku上部署ktor应用程序，我已经尝试了您所说的和任务阶段（dependsOn:['：subproject:stage'，'installDist']）
