Anyone having issues declaring coreLibraryDesugaring inside androidMain dependencies? It seems that this function does not exist for the multiplatform plugin

[Javier]

Are you applying com.android.library plugin?

[leandro]

yep

[Javier]

are you using buildSrc?

[leandro]

no… I just created a project on AS 4.1, then created a new MPP module using the Jetbrains plugin, then for the Android dependencies I declared both compileOptions { coreLibraryDesugaringEnabled true } and inside dependencies coreLibraryDesugaring com.android.tools:desugar_jdk_libs:1.0.10

[leandro]

oh, it works if I dont declare it inside androidMain’s dependencies, but as a top level dependencies block

Hi, I have the same struggle, is there an example to follow? @leandro

[leandro]

What have you tried that it didn't work? The solution is to pretty much copy what an android-only module would have

[leandro]

so basically apply the android plugin, create a dependencies {} block and add the coreLibraryDesugaring inside. You can keep KMM modules depending on kotlinx-datetime

[ptsiogas]

When doing all of the above in an Android module it works fine. I would like to apply coreLibraryDesugaring straight to the KMM module in it’s build.gradle.kts file

[leandro]

does this work for you?

apply plugin: 'com.android.library'
apply plugin: 'org.jetbrains.kotlin.multiplatform'


android {
  compileOptions {
    coreLibraryDesugaringEnabled true
  }
}

kotlin {
  android()
  ios()

  sourceSets {
    commonMain {
      dependencies {
        api libs.kotlin.datetime
      }
    }
    commonTest {
      dependencies {
      }
    }
    iosMain {
      dependencies {
      }
    }
    androidMain {
      dependencies {
      }
    }
  }
}

dependencies {
  coreLibraryDesugaring libs.desugar
}

I worked fine. Thanks a lot
