Build failed "Execution failed for task ':launcher:checkReleaseDuplicateClasses'."

[happypepper]

Hi guys, I imported the entire GooglePlayPlugins folder to my project.
I'm not quite sure why I'm getting all these duplicate class exceptions when I try to build. Anyone have an idea?

I'm using Unity 2019.4.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':launcher:checkReleaseDuplicateClasses'.

[EricBatlle]

Do you have more plugins added to your project?

[happypepper]

@EricBatlle Yeah. I have a lot. Is there any way to find out which one is causing the duplicate?

[EricBatlle]

I don't think so, you can make a Androd>Resolve, but It works half the times for me ^^'

The brute-force approach is to enable-disable your current plugins, maybe you got one that got the "classes.jar" on the lib folder and you can simply delete the file and compile again.

[jamcohen]

@happypepper were you able to resolve this?

[happypepper]

@happypepper were you able to resolve this?

Yeah I did. i removed the playcore file i got from this repo

[happypepper]

Still, I wish i knew where the other playcore is, I couldnt find it anywhere. maybe it's invisible, built into unity or something

[jamcohen]

Does your project have a mainTemplate.gradle file? That file can declare dependencies which Unity will download during a build.

[happypepper]

Does your project have a mainTemplate.gradle file? That file can declare dependencies which Unity will download during a build.

Ah yes, it does. and it contains the play:core dependency. should that be removed?

[jamcohen]

Depending on the plugins you're using, you could stick with the v1.7.3 version specified in the mainTemplate.gradle file.
You could also remove it if you wanted to use the playcore.aar (v1.10.0) packaged with our plugin instead.

I'd recommend looking at the PlayCore release notes to see if there's a compelling reason not to use v1.10.0.
