Hi,
I already have this error when I have duplicate .jar.
But here it’s not the case.
I spend my day on it, I really don’t understand this error. I tried to uninstall and re-install all my assets from scratch: the same error.
CommandInvokationFailure: Unable to convert classes into dex format. See the Console for details.
stderr[
UNEXPECTED TOP-LEVEL EXCEPTION:WWW.class …
Anybody have an idea?
Thanks a lot.
Best regards,
AB
I dont think this has anything to do with your assets but with the jdk and/or sdk tools. Did you download everything with the sdk manager ?

Are you sure you don’t have any duplicated libraries ?
The DEX tool merges all code into a single package, so in case you have multiple libraries with the same code, it will cause these conflicts.
One way to get this error is to include the same .JAR file in your project more than once.
Another way is that .JARs can actually be merged together (e.g: included in other JARs). For example, you may have some 3rd party plugin that comes as a .JAR file, but includes all of its dependencies inside. In this case you’ll still get the same classes that you already have, included in another JAR file.
Look at all your libraries in your project (JARs or AAR files) and try to analyze what you added when your project broke.
I highly recommend JD-GUI which is a tool that allows you to “peek” into JARs and see what they contain.
Let me know if any of this helped

One thing that I was made wrong is looking for the files in the Unity search. Doens’t work. You have to find the duplicate files direct in the folder.

I got something similar and solved it by removing the arr from Plugins -->Android → unity-ads-1.5.6.aar
I think this can occur when you “turn on” the ADS service by unity (using the studio services component)

For those, who are facing this error — in my case this happens because of having play-services-plus-8.4.0.aar from old version of gpg plugin and new version of plugin — 9.2.1 (which doesn’t have file with such name, or something like that).

I’m having the exact same issue. However, every time I delete the 8.4 files they seem to pop right back… I wound up going to Assets>Google Play Services>Settings and disabling Enable Background resolution.
This happens because of the “Google play resolver” (GitHub - googlesamples/unity-jar-resolver: Unity plugin which resolves Android & iOS dependencies and performs version management )

You have multiple copies of the Android support library. keep only one and you should resolve this issue. If you still can’t fix it, contact me (via the link in my signature below ).
