I’m setting up my project, including both desktop and android, to run in multiple environments, but the error below occurred. How can I run my project in different environments?
org.gradle.api.InvalidUserCodeException: Only one of the JVM targets can be configured to work with Java. The target 'common' is already set up to work with Java; cannot setup another target 'dev'

You should create different modules instead of a single module
common
your common module for interfaces
dev
mock
sit
uat
prod
All of these should be depending on
common
and implement the interfaces in their own way

Or if there is some dependency, enable mpp hierarchy(
kotlin.mpp.enableGranularSourceSetsMetadata​=​true
) and insert
dependsOn
.

Or just try to not use withJava()

@Big Chungus without withJava() only work with the desktop only project

Really? Why? Can't you use android() and jvm() targets to separate the two ends?

I have a commonUI module that has jvm() and android() targets, and i implement the commonUI module in my desktop app. If i remove
withJava()
from my desktop app, it will leave the message
Unable to find Gradle tasks to build: [:desktopApp:devMain]. 
			Build mode: COMPILE_JAVA. 
			Tests: All.
and nothing happen, but
withJava()
made it run

Ok, makes sense. Thanks for clarifying.

@Dragos Rachieru your idea sounds great, but I don’t fully understand it yet. Do you have any sample code or any document related to it? It would be great if you can share them with me

common/src/commonMain/ExampleRepository.kt
interface ExampleRepository.kt {
  fun getExamples(): List<String>
}
dev/src/commonMain/ExampleRepositoryImpl.kt
class ExampleRepositoryImpl(
  private val devNetworkSource: NetworkSource
) : ExampleRepository {

  override fun getExamples(): List<String> = devNetworkSource.fetch()

}
mock/src/commonMain/ExampleRepositoryImpl.kt
object ExampleRepositoryMock : ExampleRepository {

  override fun getExamples(): List<String> = List(10) { "Mock $it" }

}
and in your app module you add your dependencies and decide which implementation you want to use, I don't know how to explain this further, you should learn more about dependency injection and type inference
dev/build.gradle.kts
implementation(":common")
mock/build.gradle.kts
implementation(":common")
app/build.gradle.kts
implementation(":common")
implementation(":dev")
implementation(":mock")
app/src/main/kotlin/ExampleRepositoryProvider.kt
...
fun provideExampleRepository(appType: AppType): ExampleRepository {
  return when(appType) {
    AppType.Mock -> ExampleRepositoryMock
    AppType.Dev -> ExampleRepositoryImpl(createDevNetworkSource())
  }
}
...
