Jlink can be invoked using whichever means works best for your build environment e.g. The command could be run from the command line manually or automatically via an appropriate build tool plugin.
This can be done with one command (running it on a single line and using your values instead of the %% variables): %WARP_DIR%\warp-packer Then, create a single file application executable. Generate an image for your application using jlink.Copy warp-packer from this download link.Use warp-packer to create a exe out of the image and app launcher created by jlink.
