It is an Android project with Java and Kotlin code. But, my colleagues using the same code are not facing the issue — user2067340, Apr 23 '18 at 12:37
Try to reduce the level of directory structure. Bring your project as close as possible to your root directory — Sagar, Apr 23 '18 at 12:45

I guess you are the windows user, there is a file path limit of 8191 in Windows XP and above.

http://support.microsoft.com/kb/830473/en-us

The simplest way this shorten the file path, like change the project folder into D:\, and refact your project path, and always use ASCII chars for the folder name. UTF-8 chars use 2-3 bytes. or move useless dependency. or change to MAC platform. ;)

The reason is at the compile step, there is a command like javac xxxx, combine all dependences's path in one line.

Yup, this is the only way I'm aware of. If you don't want to move all your stuff, you still can use **virtual drive pointing to your original folder** ! See this [blog entry](https://www.ubergizmo.com/how-to/mount-folder-as-drive-windows) for detailed explainations ! – Sylfo Aug 30 '18 at 09:55
This is incorrect: Gradle executes its commands using [CreateProcess](https://learn.microsoft.com/en-us/windows/desktop/api/processthreadsapi/nf-processthreadsapi-createprocessa), so the maximum command size is **32,768**. – Mark Whitaker Sep 20 '18 at 08:50
Virtual drive works for me. Create a batch file; subst Z: "D:\Projects\Your Project\...." – kaya Dec 30 '18 at 10:04
This workaround really works. I can't believe how naive the developers of gradle are. – finejustice Mar 07 '19 at 11:29

path change will not work for me i have many files still getting error Any other solution ? – Ahmad Aug 01 '20 at 11:40
I had the same error because there was another instance of OpenJDK which was using some cache resource. Killing the other instances helped. – pkuszewski Mar 16 '22 at 20:55

For me this worked.

Go to Build -> Clean.
File -> Invalidate Cache and Restart

Or

It might be due to network issue. Please check connectivity.

If you are using intellij idea you can shorten command line by doing the following:

go to Run/Debug Configuration
pick classpath file in Shorten command line drop box. Example below.

Stumbled upon this recently as well. This worked for me:

subst X: C:\Users$PATH_TO_YOUR_PROJECT to create a virtual mount
Open cmd
- Type gpedit.msc
- Local Computer Policy > Computer Configuration > Administrative Templates > System > Filesystem
- enable Win32 long paths
- reboot

File -> Invalidate caches & Restart.

In my case all I had to do was move the project folder from it's original location to the desktop. The new project location became - C:\Users\YourPCName\Desktop\YourProjectName
