"Duplicate class .. found in modules ..." triggered by appcompat and lets-plot-common libraries

I am using the kotlin lets plot api, which works 100% on jupyter and in standalone apps,

however I’m trying to use it on an android app and at the moment to build I get a bunch of errors that say like this

Duplicate class kotlin.ArrayIntrinsicsKt found in modules jetified-kotlin-stdlib-1.3.72.jar (org.jetbrains.kotlin:kotlin-stdlib:1.3.72) and jetified-lets-plot-common-1.3.1.jar (org.jetbrains.lets-plot:lets-plot-common:1.3.1)

and

Duplicate class org.jetbrains.annotations.TestOnly found in modules jetified-annotations-13.0.jar (org.jetbrains:annotations:13.0) and jetified-lets-plot-common-1.3.1.jar (org.jetbrains.lets-plot:lets-plot-common:1.3.1)

I understand that I have to choose only one of the libraries to be compiled, but if I remove lets-plot from the gradle the project renders unusable at ‘grafica.kt’

My question is:

Can I remove ‘org.jetbrains.kotlin:kotlin-stdlib:1.3.72’ and ‘org.jetbrains:annotations:13.0’ safely? and If so, how can I do this?

Thanks in advance!

I’ve opened the same issue at :

where I’ve attached a sample project

@descent2oblivion I’ve done what @ilya-g suggested. Could you try upgrading to lets-plot-kotlin-api 0.0.22-SNAPSHOT ? It depends on lets-plot-common 1.4.3-SNAPSHOT which is clear from Kotlin and other external dependencies.

[ilya-g]

It looks like lets-plot-common.jar artifact is an uber-jar that bundles classes from all of its dependencies, including kotlin-stdlib. This approach can cause problems in certain environments, for example in the modular Java environment on the module path or in Android apps as described above.

Consider providing your main artifact lets-plot-api that lists all its dependencies as plain dependencies instead of bundling them, and provide an uber-jar if needed as a distinct artifact variant or a separate artifact.
