& ldquo; CommandInvokationFailure: Unable to convert classes to dex format. & rdquo; with Unity Upsight Plugin Build for Android

advertisements

I am running into an Exception when I try to build my Unity project for Android since I imported and configured the Upsight (http://www.upsight.com/) plugin. The log message is truncated so I cannot see where the conflict comes from (see below).

It would be great, if someone knew how to find the exact source of this error. Maybe the truncating can be deactivated somehow or this problem is known for Upsight when using other plugins. I use some more plugins like Unity Purchasing, Mobile Social and Fyber. Maybe one of these is known to cause problems in combination with Upsight!?

I appreciate any idea or workaround. I need to get the plugin running! Thank you in advance!

I also encountered the same problem two weeks ago. This error usually comes when you have imported more than one plugins that have same ".jar" files in assets folder.

I suggest you to find repeating ".jar" in project folder by typing "*.jar" in search bar. And then find for repeating files and delete one of them.

In my case, I had imported two different versions of Google VR sdks. So they had same .jar files.... When I searched for them, i found "example.jar" two times in search results. and deleted one of them. It solved the problem.
