Addressable Assets Error: INCORRECT HASH

Hi,

since a couple of days we have the error INCORRECT HASH when building the Addressables Assets for our project.

The full error looks like this:

Code (CSharp):

1. Exception: INCORRECT HASH: the same hash (53430400) for different dependency lists:
2. source 1: System.Collections.Generic.HashSet`1[System.Object]
3. source 2: System.Collections.Generic.HashSet`1[System.Object]

The error is not 100% reproducible. 7 of 10 times the build of the addressable assets is failing with with INCORRECT HASH.

Unity: 2018.4.8f1
Addressables: 1.2.4

[Update]
I found in the the Addressables 1.2.2 release notes: Fixed hash calculations to avoid collisions.
It seems the change in the hash calculation is causing the issue. We had to downgrade downgrade to 1.1.10.

 

I also just updated to 1.2.4 and see this happening on our build machines. I was previously on 1.1.10 also and didn't have this issue. Looks like I'll have to revert back now.

I'm in Unity 2019.1.11f1

 

@DavidUnity3d Is there a way to move this post into the Addressables forums? Don't want it to go unnoticed.

 

Hi @DavidUnity3d,

I'm sorry I saw too late that there is an own forum for the addressable.
We fixed the issue for now with a workaround condensed from this thread: https://forum.unity.com/threads/bug-lot-of-bundle-dependencies-will-surely-fail.693682/
