我对Kotlin和Ktor以及Gradle很新,想尝试Ktor,所以经历了here解释的步骤,最后得到了这段代码,截图显示的结构:
如所见,有很多错误,如何修复它们?
package blog
import org.jetbrains.ktor.netty.*
import org.jetbrains.ktor.routing.*
import org.jetbrains.ktor.application.*
import org.jetbrains.ktor.host.*
import org.jetbrains.ktor.http.*
import org.jetbrains.ktor.response.*
fun main(args: Array<String>) {
embeddedServer(Netty, 8080) {
routing {
get("/") {
call.respondText("My Example Blog", ContentType.Text.Html)
}
}
}.start(wait = true)
}
build.gradle
文件自动生成为:
group 'Example'
version '1.0-SNAPSHOT'
buildscript {
ext.kotlin_version = '1.1.4-3'
repositories {
mavenCentral()
}
dependencies {
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
apply plugin: 'java'
apply plugin: 'kotlin'
sourceCompatibility = 1.8
repositories {
mavenCentral()
}
dependencies {
compile "org.jetbrains.kotlin:kotlin-stdlib-jre8:$kotlin_version"
testCompile group: 'junit', name: 'junit', version: '4.12'
}
compileKotlin {
kotlinOptions.jvmTarget = "1.8"
}
compileTestKotlin {
kotlinOptions.jvmTarget = "1.8"
}

您有不完整的build.gradle
脚本(缺少依赖项) - 有关详细信息,请参阅here。这是好的:
group 'Example'
version '1.0-SNAPSHOT'
buildscript {
ext.kotlin_version = '1.1.4-3'
repositories {
mavenCentral()
}
dependencies {
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
apply plugin: 'java'
apply plugin: 'kotlin'
sourceCompatibility = 1.8
ext.ktor_version = '0.4.0'
repositories {
mavenCentral()
maven { url "http://dl.bintray.com/kotlin/ktor" }
maven { url "https://dl.bintray.com/kotlin/kotlinx" }
}
dependencies {
compile "org.jetbrains.kotlin:kotlin-stdlib-jre8:$kotlin_version"
compile "org.jetbrains.ktor:ktor-core:$ktor_version"
compile "org.jetbrains.ktor:ktor-netty:$ktor_version"
compile "ch.qos.logback:logback-classic:1.2.1"
testCompile group: 'junit', name: 'junit', version: '4.12'
}
compileKotlin {
kotlinOptions.jvmTarget = "1.8"
}
compileTestKotlin {
kotlinOptions.jvmTarget = "1.8"
}
kotlin {
experimental {
coroutines "enable"
}
}

我建议使用IntelliJ Ktor plugin引导您的应用程序。 ./gradlew run
脚本在使用此配置的情况下即开即用,而无需您随意使用Gradle配置。这是最简单的入门方法。
以下是使用以下配置的示例Ktor应用程序:https://gitlab.com/tinacious/ktor-example
如果您想从IntelliJ中运行应用程序,请查看此答案以获取我使用的运行配置:https://stackoverflow.com/a/65350680/1870884
