Building an AppImage from Windows

Creating AppImages
1

Hi,
I have a Java Application for which I’d like to make an AppImage.
I’m packaging that application with the maven’s javapackager plugin targeting Linux, on a Windows workstation.
For now, the output of that packaging is:
The content of the tar.gz file is:

  • a PNG file (provided by me - 128px/128px )
  • a folder with all the .jar libs
  • an executable file (bash shell)

I’d like to make an AppImage out of this in order to have the right .desktop file created.

Is there a way to build an AppIlmage from Windows ?

PS: I’m using Netbeans as IDE.
