I follow the instructions but when downloading OpenJDK 11 + OpenJFX 11 from the download link I only have the file jdk-11.0.1.
Should I download OpenJFX 11 separately? In the affirmative case, do I have to in the same folder c: \\java?
Run the project in release mode. Zip the project folder (NOT with File - Export as zip), including all nested folders and upload it. You will probably need to upload it to Google drive or a similar service and post the link.
I don't know how, but that must be the problem. I have had to decompress the library in the same folder.
I have tried decompressing the example in a new folder, those files do not appear and everything works.
I am very sorry for the time I have wasted.
