Unable to build iliasDownloaderTool

[Toorero]

I've tried to build the iliasDownloaderTool by myself but I'm running into several errors.

If I compile it with openjdk-14-jdk there is a huge stack-trace:

I should also mention that I have quite similar issues as described in #15 by @vonHartz. I felt it would be a great idea if that could be split out thread #15 because it's not quite related to the original title.

[DeOldSax]

As mentioned in the readme, the current JDK is JDK 8, preferably with javafx included.
To overcome this issue in the future and make it ready for JDK 11 and upcoming LTS versions, see #51

[Toorero]

As I already mentioned EVEN IF I build it with openjdk-8-jdk and openjfx installed I still get the same error.

[DeOldSax]

from the error it looks like not all modules from openjfx are included
--> https://mvnrepository.com/artifact/org.openjfx
--> controls, animation packages
