Android studio: Parameter 'directory' is not a directory

Question

When I try to build my project, I get such a mistake:

FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:dataBindingGenBaseClassesDebug'.
> Parameter 'directory' is not a directory

Does this answer your question? [java.lang.IllegalArgumentException: Parameter 'directory' is not a directory in android](https://stackoverflow.com/questions/54018148/java-lang-illegalargumentexception-parameter-directory-is-not-a-directory-in) — Android_id, Aug 14 '20 at 06:37

From an answer to a similar question:

Delete the .gradle directory (in the project base directory)
Invalidate Caches and restart Android Studio (if necessary)

EDIT: Step 2 doesn't appear necessary on *nix systems

Just the first step, i.e. `rm -rf .gradle/` did the trick for me. – Erik Nov 20 '20 at 15:18

For me was enough first step. `rm -rf .gradle/` – Black_Zerg Feb 24 '21 at 11:28

Worked for me too. I saved the files before delete and grep'ed for the word directory and none had it. Weird... – steven smith Mar 04 '21 at 19:53
