[英]ktor dependencies not resolved in ios module of multiplatform project
I have a kotlin-multiplatform project targeting iOS and Android.我有一个针对 iOS 和 Android 的 kotlin-multiplatform 项目。 Ktor http client is used in common module. Ktor http 客户端用于公共模块。
Everything works great with Android app.一切都适用于 Android 应用程序。 But when building project with iOS lib, I receive following exceptions:但是在使用 iOS lib 构建项目时,我收到以下异常:
> Task :app:compileKotlinIos FAILED
src/commonMain/kotlin/com/ottamotta/mozoli/api/MozoliApiKtor.kt:4:8: error: unresolved reference: io
import io.ktor.client.HttpClient
^
src/commonMain/kotlin/com/ottamotta/mozoli/api/MozoliApiKtor.kt:5:8: error: unresolved reference: io
import io.ktor.client.features.feature
...and other ones, saying none of the ktor dependencies have been resolved. ...和其他人,说没有任何 ktor 依赖项已解决。

Here is the code of the file from common module which generates errors:这是来自 common 模块的文件的代码,它生成错误:

I was having the same exact issue as you.我和你有同样的问题。 Built and works flawlessly for the Android app, but the iOS module cannot find any Ktor, coroutine, or kotlinx serialization class.为 Android 应用程序构建并完美运行,但 iOS 模块找不到任何 Ktor、协程或 kotlinx 序列化类。
Following along https://github.com/adrianbukros/github-multiplatform-example , and trying to copy their set up, I finally got the packForXCode
task to work by copying some of their gradle set up namely:沿着https://github.com/adrianbukros/github-multiplatform-example ,并尝试复制他们的设置,我终于通过复制他们的一些 gradle 设置来使packForXCode
任务工作:
Their common module build.gradle
, which should look like this:他们的公共模块build.gradle
,应该是这样的:
apply plugin: 'kotlin-multiplatform'
apply plugin: 'kotlinx-serialization'
kotlin {
targets {
fromPreset(presets.jvm, "android")
fromPreset(presets.iosX64, "ios_x86_64")
fromPreset(presets.iosArm64, "ios_arm64")
configure([ios_x86_64, ios_arm64]) {
compilations.main.outputKinds("FRAMEWORK")
}
}
sourceSets {
commonMain.dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib"
implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core-common:$coroutines_version"
implementation "org.jetbrains.kotlinx:kotlinx-serialization-runtime-common:$serialization_version"
implementation "io.ktor:ktor-client-core:$ktor_version"
implementation "io.ktor:ktor-client-json:$ktor_version"
}
androidMain.dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core:$coroutines_version"
implementation "org.jetbrains.kotlinx:kotlinx-serialization-runtime:$serialization_version"
implementation "io.ktor:ktor-client-core-jvm:$ktor_version"
implementation "io.ktor:ktor-client-json-jvm:$ktor_version"
}
iosMain.dependencies {
implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core-native:$coroutines_version"
implementation "org.jetbrains.kotlinx:kotlinx-serialization-runtime-native:$serialization_version"
implementation "io.ktor:ktor-client-ios:$ktor_version"
implementation "io.ktor:ktor-client-core-ios:$ktor_version"
implementation "io.ktor:ktor-client-json-ios:$ktor_version"
}
configure([ios_x86_64Main, ios_arm64Main]) {
dependsOn iosMain
}
}
}
// workaround for https://youtrack.jetbrains.com/issue/KT-27170
configurations {
compileClasspath
}
task packForXCode(type: Sync) {
final File frameworkDir = new File(buildDir, "xcode-frameworks")
final String configuration = project.findProperty("CONFIGURATION")?.toUpperCase() ?: "DEBUG"
final String arch = project.findProperty("ARCHS") ?: "x86_64"
dependsOn kotlin.targets."ios_${arch}".compilations.main.linkTaskName("FRAMEWORK", configuration)
from { kotlin.targets."ios_${arch}".compilations.main.getBinary("FRAMEWORK", configuration).parentFile }
into frameworkDir
}
tasks.build.dependsOn packForXCode
And their settings.gradle
file which should look like this:他们的settings.gradle
文件应该是这样的:
enableFeaturePreview("GRADLE_METADATA") // IMPORTANT!
include 'commoncode'
include 'app'
If it's still not working, look at all of their *.gradle
and gradle.*
files and see how yours are different.如果它仍然不起作用,请查看他们所有的*.gradle
和gradle.*
文件,看看您的文件有何不同。
That finally allowed the task to pass for me, and I can use my Kotlin Ktor code in XCode.这最终让我完成了任务,我可以在 XCode 中使用我的 Kotlin Ktor 代码。 However, now Android Studio is saying "Kotlin is not configured" for the shared iOS module.但是,现在 Android Studio 对共享的 iOS 模块说“未配置 Kotlin”。 I will report back if I figure out why, and if you find something, please share!如果我找出原因,我会报告回来,如果你发现了什么,请分享!
EDIT Changed the common module build.gradle
to look like this, seems like everything is working well!编辑将通用模块build.gradle
更改为如下所示,似乎一切正常!
apply plugin: 'kotlin-multiplatform'
apply plugin: 'kotlinx-serialization'
kotlin {
targets {
fromPreset(presets.jvm, 'android')
// Change to `presets.iosArm64` to deploy the app to iPhone
fromPreset(presets.iosX64, 'ios') {
compilations.main.outputKinds('FRAMEWORK')
}
}
sourceSets {
commonMain.dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib"
implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core-common:$coroutines_version"
implementation "org.jetbrains.kotlinx:kotlinx-serialization-runtime-common:$serialization_version"
implementation "io.ktor:ktor-client-core:$ktor_version"
implementation "io.ktor:ktor-client-json:$ktor_version"
}
androidMain.dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core:$coroutines_version"

implementation "io.ktor:ktor-client-core-ios:$ktor_version"
implementation "io.ktor:ktor-client-json-ios:$ktor_version"
}
}
}
// workaround for https://youtrack.jetbrains.com/issue/KT-27170
configurations {

}
task packForXCode(type: Sync) {
final File frameworkDir = new File(buildDir, "xcode-frameworks")
final String mode = project.findProperty("XCODE_CONFIGURATION")?.toUpperCase() ?: 'DEBUG'
inputs.property "mode", mode
dependsOn kotlin.targets.ios.compilations.main.linkTaskName("FRAMEWORK", mode)
from { kotlin.targets.ios.compilations.main.getBinary("FRAMEWORK", mode).parentFile }
into frameworkDir
doLast {
new File(frameworkDir, 'gradlew').with {
text = "#!/bin/bash\nexport 'JAVA_HOME=${System.getProperty("java.home")}'\ncd '${rootProject.rootDir}'\n./gradlew \$@\n"
setExecutable(true)
}
}
}
tasks.build.dependsOn packForXCode
As of now kotlin multiplatform for iOS does not run on windows.截至目前,适用于 iOS 的 kotlin 多平台无法在 Windows 上运行。 This would explain why only the dependencies in your iosmain code wont resolve.这将解释为什么只有 iosmain 代码中的依赖项无法解析。
