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:

Caused by: jav         


        

Answer 1

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

1. Delete the .gradle directory
2. Invalidate Caches and restart Android Studio.

Answer 2

Your "File" type should reference to a FOLDER and not a FILE. Android Source Code does this:

if (!directory.isDirectory()) {
    throw new IllegalArgumentException("Parameter 'directory' is not a directory: " + directory);
}

so you are passing a File variable that doesn't points to a Folder but a something else.
