java.lang.IllegalArgumentException: Parameter 'directory' is not a directory in android

Question

I rebuilt my project and got this error. I'm unable to find where it's coming from. The full log is:

share your code as well – Ito

Does this error while executing a Gradle task? If so, include your build.gradle file. – Pint

It might just be an android thing here, not into it, but the error also happens when you try to get a file from a path that just is not there. You might be on another machine than you think you are. Check the working directory and find out whether the paths to all needed files are right. See Parameter 'directory' is not a directory for a parameter which is a directory, with other answers as well. – Disruption

Answer 1

I've had the same problem. All I did was:

1. Delete the .gradle directory under the project root files
2. Invalidate Caches and restart Android Studio.

To clarify, the .gradle directory is under the project instead of the one under user's home directory. – Alveraalverez

Very weird, changed branches and saw this for the first time. Thank you for the solution. – Misapply

As in case of gentleman above, my build broke after just switching between git branches, and this answer helps. – Molecular

The tip for .gradle under project dir was helpful, as I thought people meant the home dir .gradle, which didn't fix it for me – Pooi
