I've just installed BlueJ .deb version over Ubuntu 20.04. Installed successfully and created new project also. But it doesn't open editor when I double clicked the java source file. I have openjdk(14) and openjfx(11) installed. Thanks.

Same problem here. It seems that openjfx is not compatible with bluej and others apps. bug openjfx

So I installed the "generic version" of bluej and the recommended openjfx lib: Install bluej:

  • Download the openjfx from gluon Unpack its "lib" dir to /usr/shares/openjfx11 (or another name)
  • Start the installation of bluej with java -jar path/to/bluej.jar
  • In the opened dialog set the correct jfx path as mentioned above..
