Program type already present: com.google.common.util.concurrent.internal.InternalFutureFailureAccess

Question

I'm getting this error while compiling my project. I've found out that's because of Guava, and reason why I'm getting this, is other lib is using Guava (this component of Guava) too (maybe other version, or just duplicated). I can't find out which one. I am using Guava to do hashing while saving my password while logging. I know it's necessary to exclude it, but i don't know exactly what and how.

Answer 1

I found a workaround: just use 'com.google.guava:guava:26.0-android' instead of 'com.google.guava:guava:27.0-android'. Then the issue gone!

And, I also hope someone can tell the root cause.

Answer 2

The latest release of Guava (27.0.1: https://github.com/google/guava/releases/tag/v27.0.1) has fixed this problem. Just use this:

implementation 'com.google.guava:guava:27.0.1-android'
