请帮忙。我将 Android studio 从 Iguana 更改为 LadyBug，但该项目无法编译。编译期间出现两个错误 :app:kaptGenerateStubsDebugKotlin' 和 Unknown Kotlin JVM target: 21:
Execution failed for task ':app:kaptGenerateStubsDebugKotlin'.
> Error while evaluating property 'compilerOptions.jvmTarget' of task ':app:kaptGenerateStubsDebugKotlin'.
> Failed to calculate the value of property 'jvmTarget'.
> Unknown Kotlin JVM target: 21
我重新安装了 JVM 和 JDK。与所有实现一样，我在当前版本中添加了它们。
这是我的 gradle 文件： ...
plugins {
id("com.android.application")
id("org.jetbrains.kotlin.android")
id("org.jetbrains.kotlin.kapt")
}
android {
namespace = "com.ollo.stopsindicator"
compileSdk = 34
defaultConfig {
applicationId = "com.ollo.stopsindicator"
minSdk = 26
targetSdk = 34
versionCode = 28
versionName = "1.28"
testInstrumentationRunner = "androidx.test.runner.AndroidJUnitRunner"
vectorDrawables {
useSupportLibrary = true
}
}
buildTypes {
release {
isMinifyEnabled = false
proguardFiles(
getDefaultProguardFile("proguard-android-optimize.txt"),
"proguard-rules.pro"
)
}
}
compileOptions {
sourceCompatibility = JavaVersion.VERSION_1_8
targetCompatibility = JavaVersion.VERSION_1_8
}
kotlinOptions {
jvmTarget = "1.8"
}
buildFeatures {
compose = true
}
composeOptions {
kotlinCompilerExtensionVersion = "1.5.15"
}
packaging {
resources {
excludes += "/META-INF/{AL2.0,LGPL2.1}"
}
}
}

我不知道为什么 JVM 目标是 21，我没有在任何地方设置类似的东西。 ...

我希望我的经历能帮助别人。最重要的是仔细填写 build.gradle.kts(app) 文件中配置的准确选择。
我做了以下更改来运行我在 Android Studio Iguana 中编写的项目。它在 Android Studio Lady Bug 上不起作用。我安装了 Android Studio Koala Feature Drop，然后更改了配置。
要让一切顺利进行，最重要的是选择 Compose to Kotlin Compatibility Map：
https://developer.android.com/jetpack/androidx/releases/compose-kotlin
compileOptions {
sourceCompatibility = JavaVersion.VERSION_17
targetCompatibility = JavaVersion.VERSION_17
}
kotlinOptions {
jvmTarget = "17"
}
buildFeatures {
compose = true
}
composeOptions {
kotlinCompilerExtensionVersion = "1.4.2"
}
再次非常感谢 Robert，他给了我检查配置的提示。
