Warning when building app: "Expected stack map table for method with non-linear control flow."

Question

I have a project on which I worked last year. Recently I started working on it again but wanted to update everything that was possible. I managed to resolve basically all problems except this one. I can't find anything online about this warning. I get it when I build the project. I tried downloading and using the latest tapjoy jar but it still appears. In the warning there is a path to a cache folder so I tried deleting it but id didn't change anything; maybe I'm getting this warning because those folders are missing?

The full warning is like this:

AGPBI: {"kind":"warning","text":"Expected stack map table for method with non-linear control flow.","sources":[{"file":"C:\\Users\\black\\.gradle\\caches\\transforms-3\\91514d5ad9a3a762574d6c5e2880beba\\transformed\\jetified-tapjoyconnectlibrary.jar"}],"tool":"D8"}

The problem is that i have around 200 lines of this warning in console and I would like to solve them.

Has anyone seen this warning before and knows how to fix it? Obviously any help is much appreciated.

Answer 1

The missing folder should have nothing to do with this warning. I had this problem in the process of writing custom gradle plug-ins. It seems that ClassWriter or ClassVisitor in ASM did not implement any method, there will be this warning, but that does not affect normal functionality. You can check that your project has used those gradle plug-ins, perhaps these plug-ins are caused by the update of the problem.
