Bug BUG: A meta data file (.meta) exists but its asset 'Assets/StreamingAssets/aa' can't be found

Building a Windows Standalone Player with Unity 2019.3.7f1 and Addressables 1.7.5, causes the Addressables System to output the following warning always:

The entire related log is:

Code (CSharp):

1. Copying Addressables data from Library/com.unity.addressables/StreamingAssetsCopy/aa/Windows to C:/Users/crash/Documents/TestProject/Assets/StreamingAssets/aa/Windows.  These copies will be deleted at the end of the build.
2. UnityEngine.Debug:Log(Object)
3. AddressablesPlayerBuildProcessor:OnPreprocessBuild(BuildReport) (at Library/PackageCache/com.unity.addressables@1.7.5/Editor/Build/AddressablesPlayerBuildProcessor.cs:37)
4. UnityEditor.BuildPipeline:BuildPlayer(BuildPlayerOptions)
5.  
6.  
7. Deleting Addressables data from C:/Users/crash/Documents/TestProject/Assets/StreamingAssets\aa.
8. UnityEngine.Debug:Log(Object)
9. AddressablesPlayerBuildProcessor:CleanTemporaryPlayerBuildData() (at Library/PackageCache/com.unity.addressables@1.7.5/Editor/Build/AddressablesPlayerBuildProcessor.cs:26)
10. AddressablesPlayerBuildProcessor:OnPostprocessBuild(BuildReport) (at Library/PackageCache/com.unity.addressables@1.7.5/Editor/Build/AddressablesPlayerBuildProcessor.cs:17)
11. UnityEditor.BuildPipeline:BuildPlayer(BuildPlayerOptions)
12.  
13.  
14. A meta data file (.meta) exists but its asset 'Assets/StreamingAssets/aa' can't be found. When moving or deleting files outside of Unity, please ensure that the corresponding .meta file is moved or deleted along with it.

Looking at the

AddressablesPlayerBuildProcessor.CleanTemporaryPlayerBuildData

code shows this line:

Code (CSharp):

1. Directory.Delete(addressablesStreamingAssets, true);

... which deletes the directory, but not the .meta file of that directory.

Reproduce

• Build Windows Standalone Player
• Unfocus / Focus Unity editor

1) Please fix that you also delete the .meta afterwards to avoid getting the warning with every build.

2) Is there a way to turn off the "Copying Addressables data" message? I understand that's important to output warnings and errors, but this log isn't particular useful to me.


PS: No idea why Unity generates .meta files for files inside the StreamingAssets directory, this could be another bug. But it's been like this always.

 

I updated Addressables to 1.10.0, the issue described above still persists.

 

I'm being annoyed by this issue as well, but i don't need to build anything. StreamingAssets was auto added to my directory (not sure why/when) and Addressables has been complains about it every time refresh my code:



I've deleted the folder and the errors have stopped. And the folder doesn't seem to come back.

Edit: Nevermind, the folder and error messages came back on build

 

That's because they copy

aa

to streaming assets in the pre-build process, then delete it in the post-build process. Unity itself can generate the meta file within that process that Addressables is not accounting for.

 

Bug still there in Unity 2020.2a19 + Adressables 1.13.1

 

I have no idea what `StreamingAssets/aa` is so it's quite annoying to have it created in my project files and also getting the warning in my console all the time. Any solution to this?

 

Fix it already!!!!

 

I can no longer reproduce the issue with Addressable 1.16.15. I assume it has been fixed. Thank you!

 

Hi.

I am facing a similar problem (or maybe not).

error: Callback provided streaming assets file conflicts with file already present in project. Project file 'StreamingAssets/aa/catalog.json'. Callback provided file 'Library/com.unity.addressables/aa/WebGL/catalog.json'.
UnityEngine.GUIUtilityrocessEvent (int,intptr,bool&)

 

i solved it. it happens when using addressable updated from 2020ver to 2021ver. you need to delete the filename: StreamingAssets in Asset folder.
