The import javafx cannot be resolved

Question

I installed Eclipse IDE today on my Ubuntu Linux and then installed JavaFX using \'Install New Software\' and when I created a javafx project, I got the following error in M

Answer 1

Here's how to set it up on Ubuntu Linux with Maven:

1) Install OpenJFX package, check where did it put the files.

      sudo apt install openjfx
      dpkg-query -L openjfx

You might end up with version for JDK 11. In which case, either follow with installing a new OpenJDK, or set a version of OpenJFX for JDK 8.

2) Put it to your Maven project as a system-scoped dependency.

Note this is the lazy and not-so-nice way. Properly, you should install the jars like this:

dpkg-query -L openjfx | grep -E '.jar$' | xargs -l -I{} \
  mvn install:install-file -Dfile="{}" -DgroupId=javafx \
    -DartifactId=$(echo $JAR | tr '.' '-') -Dversion=1.0 -Dpackaging=jar

And then use it as a normal compile-scoped dependency.
