java.lang.VerifyError: Operand stack overflow for google-ads API and SBT

Question

I am trying to migrate from Google-AdWords to google-ads-v10 API in spark 3.1.1 in EMR. I am facing some dependency issues due to conflicts with existing jars. Initially, we were facing a dependency related to Protobuf jar:

Exception in thread "grpc-default-executor-0" java.lang.IllegalAccessError: tried to access field com.google.protobuf.AbstractMessage.memoizedSize from class com.google.ads.googleads.v10.services.SearchGoogleAdsRequest
    at com.google.ads.googleads.v10.services.SearchGoogleAdsRequest.getSerializedSize(SearchGoogleAdsRequest.java:394)
    at io.grpc.protobuf.lite.ProtoInputStream.available(ProtoInputStream.java:108)

In order to resolve this, tried to shade the Protobuf jar and have a uber-jar instead. After the shading, running my project locally in IntelliJ works fine, But when trying to run an executable jar I created I get the following error:

Exception in thread "main" io.grpc.ManagedChannelProvider$ProviderNotFoundException: No functional channel service provider found. Try adding a dependency on the grpc-okhttp, grpc-netty, or grpc-netty-shaded artifact

I tried adding all those libraries in --spark.jars.packages but it didn't help.

Has anyone ever encountered such an issue?

Solved this by using the google-ads-shadowjar as an external jar rather than having a dependency on google-ads library. This solves the problem of having to deal with dependencies manually but makes your jar size bigger.
