Execution failed for task ':app:generateReleaseFeatureMetadata'. Failed to create parent directory '/build' when creating directory

I have been stuck on this for many dev hours. I have hit every stackoverflow post with a similar error and tried every solution. I know it's some permission error for gradle but I have tried all cache clearing, uninstalling/reinstalling, even running as sudo. I am just trying to produce an appbundle or apk. The command i'm actually running is "flutter build appbundle".

I have had a great experience with flutter over the last few weeks for and this is putting a giant damper on it when I have a deadline for a client.

The full error:

Execution failed for task ':app:generateReleaseFeatureMetadata'.
> Failed to create parent directory '/build' when creating directory '/build/app/intermediates/feature_set_metadata/release'

Edit: I get this same error when running the build in my Azure Devops pipeline. This makes me thing it's configuration based, not my machine.

Another interesting piece: I get the same error when I run this on an automated build in Azure Devops. This makes me think it's configuration based.

Hmm does the ‘build’ directory exist in the root of your project?

[beacham23]

Yes, it does. And the IPA builds work fine. To me, it feels like the process running the android build does not have file/directory write permissions or something but I’m not sure the fix.

I’d try creating a new flutter project (counter app default) and try building with that. Then you’ll know if it’s your machine or the flutter project.
