IntelliJ + Java11 fails to build, javafx.animation.PauseTransition error

[klabarge]

Creating bug report for documentation purposes.

Issue

Java: AdoptOpenJDK (build 11.0.3+7)
IntelliJ: Community 2018.1
OS: macOS Mojave (10.14.6)

When trying to use AdoptOpenJDK 11/Java 11 to build the project, building may fail with the below error:

Error:(3, 24) java: cannot access javafx.animation.PauseTransition
  bad class file: /Users/kyle/tray/lib/javafx-sdk-11.0.2/lib/javafx.graphics.jar(javafx/animation/PauseTransition.class)
    class file has wrong version 54.0, should be 52.0
    Please remove or make sure it appears in the correct subdirectory of the classpath.

Resolution

If ant builds successfully from the terminal, IntelliJ's internal ant may be causing issues.

• Upgrade to the latest version of IntelliJ. At the time of writing, this was version 2019.1
