Right click on your project and go to build path > Configure build path. Under libraries, click on "Add library..." button. Add JavaFX SDK to your project. This will resolve your issue.

Could this be used for Maven projects?
I believe the choice JavaFX SDK only becomes available if the e(fx)clipse plug-in has been installed. (Please correct me if I'm wrong.) This is available through help/EclipseMarketplace.
@Line I am able to use this with a Java 8 Maven project, yes. I don’t believe it affects dependencies in pom.xml.

Not sure since I can't reproduce this issue, but do you have e(fx)clipse installed? If not, try installing it- it seems to help Eclipse to be more compatible with javaFX.

If you already have it, or if it doesn't help, try the solutions posted here, here, and here.
