@mai93 @sgowroji beta channel is broken, we need a hotfix for this

[mai93]

The release currently in beta v2024.08.27 only contains the first commit from this project, it does not have base/src/com/google/idea/blaze/base/model/ExternalWorkspaceDataProvider.java, is a hotfix still needed?

[mtoader]

If the provider is not in, hotfix is not needed.

Right!
