In android project depending on ktor & coroutines having
More than one file was found with OS independent path 'META-INF/kotlinx-coroutines-core.kotlin_module'

Same files are defined in following deps

org.jetbrains.kotlinx:kotlinx-coroutines-core:1.3.3
org.jetbrains.kotlinx:kotlinx-coroutines-core-common:1.3.3

android.packagingOptions pickFirst/exclude helps as workaround

What AGP version are you using?

[jbruchanov]

AGP=3.5.3
kotlin=1.3.61

I cannot reproduce it. How do you add dependency to kotlinx-coroutines to your build? Can you share the reproducer build file?

[jbruchanov]

quick overview
Project

• app (depends on android_lib_module1 & android_lib_module2)
• android_lib_module1 (depends on ktor& droid coroutines)
• android_lib_module2 (depends on droid coroutines)

both lib_modules released in mavenLocal
app is using them both from mavenLocal

I'll send a repo link later today

both repos have just deps simply as implementation

dependencies {
    implementation "io.ktor:ktor-server-jetty:$ktor"
    implementation "org.jetbrains.kotlinx:kotlinx-coroutines-android:$kotlin_coroutines"


    ...
}

I see. That's because of ktor, but I don't think it is possible to prevent a dependency to kotlinx-coroutines-core from appearing in ktor build, so we need to rename the module name for kotlinx-coroutines-common.
