Hi guys,
I have a strange error raised by KotlinDce:

error: duplicate target file will be created for '/Users/gaetan/.gradle/caches/modules-2/files-2.1/org.jetbrains.kotlin/kotlin-stdlib-js/1.2.61/6e6ada4e826d8c66053f9383a6778b2324853f2/kotlin-stdlib-js-1.2.61.jar!kotlin.js' and '/Users/gaetan/dev/data2viz/time/d2v-time-js/build/libs/d2v-time-js-0.6.0.jar!lib/kotlin.js

Has anyone already seen this message and understood the problem?

yes

[coder82]

it throws such error when u have a duplicate .js in your jar dependencies

[coder82]

exclude duplicate .js inside your jar task

[gaetan]

It seems to be some gradle plugin desynchronization. It works now without any modification in gradle scripts.

[coder82]

this is what I had to do to avoid it, to me the problem is deterministic:

[coder82]

eachFile {
if(it.path.endsWith("kotlin.js") ||
it.path.endsWith("kotlinx-coroutines-core.js") ||
it.path.endsWith("kotlinx-html-js.js") ||
it.path.endsWith("kotlinx-serialization-runtime-js.js") ||
it.path.endsWith("kotlinx-atomicfu.js"))
it.exclude()
}

[coder82]

this inside the jar {} task

[coder82]

in my case it happens because I have the classic dependency structure core-->app, and I compile the kotlin dependencies already in the core, then in the app as well, hence it finds duplicates

[coder82]

so in the app I exclude the dependency

[coder82]

and don't forget:
duplicatesStrategy = DuplicatesStrategy.EXCLUDE

[coder82]

inside jar {}
