On Windows you'll need to enable long file name support. There's a key in the registry or something (sorry not a Windows user). Google should help from here :-)

You need to enable the long name support for:

- Windows file system

- Git

- IntelliJ Idea

Idea is the only one that notices the issue by itself and asks if you want to enable it.

Then if you are building workbench projects you might not be able to build the showcases or wars with GWT. This is because the Maven GWT plugin has not support for long file names.

The workaround I use is to use Windows Subsystem for Linux. So I installed Ubuntu into my Windows and I can run the war builds with it. Or you can just use Linux in virtual box.

Thank you for your response !

I'm using Eclipse IDE non IntelliJ. But even if I try to build it with the command prompt I have the same problem !

I will try to build it with the Mac OS
