Answer 1

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

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.

Answer 2

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

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

Answer 3

For me this worked.

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

Or

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

Answer 4

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

Answer 5

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

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