How to install OpenJFX 11

Question

I am trying to install the latest version of BlueJ, and it requires JDK 11 and OpenJFX. I have updated from Java 8 to 11 now, but I cannot find a way to actually install OpenJFX. I've tried to check the version of Open JFX, but I get an error message, and GDebi installer says that the dependancy is not there. No, sudo apt-get install openjfx is not working. Could anyone please help?

Output: dpkg: dependency problems prevent configuration of bluej: bluej depends on openjfx (>= 11); however: Version of openjfx on system is 8u60-b27-4. dpkg: dependency problems prevent configuration of bluej: bluej depends on openjfx (>= 11); however: Version of openjfx on system is 8u60-b27-4.

Answer 1

Looks like your openjfx is in older version, version for Java 8. You can either:

• purge old installation and install openjfx-11,
• download archive from openjfx website, extract it and link your projects to extracted directory.

Maybe there is an option to force installation of openjfx-11 but I prefer to purge old files first. Otherwise you may have a "little mess" later on.
