AssetBundle.Contains does not find assets when bundles are built using CompatibilityBuildPipeline.BuildAssetBundles

Asset Bundles


Reproduction steps:
1. Open the attached project ("")
2. Build asset bundles (Build > AssetBundles: Standalone)
3. Check if they contain "icon.png" asset (Build > Check Bundles)
4. Inspect Console logs

Expected result: 'AssetBundle.Contains' returns true
Actual result: 'AssetBundle.Contains' returns false, even though the asset is in the bundle

Reproducible with: 2018.4.23f1, 2019.4.1f1, 2020.1.0b13, 2020.1.0a15
Reproducible with package versions: 1.5.1, 1.7.3
Couldn't test with package versions 1.8.2, 1.8.4 because of case 1252686

Note: Loading the asset using the path taken from ".GetAllAssetNames()" method succeeds, but ".Contains()" method with the same path fails.

  1. Resolution Note (fix version 2020.2):

    Fixed edge case with AssetBundle.Contains API when the bundle is built with Scriptable BuildPipeline.
