Steps to fix:

  1. Delete the JavaFX sdk (you don’t need it).

  2. Delete old Java versions (they are obsolete).

  3. Update your IntelliJ IDE and IDE plugins to the most recent release, 2021.3.2+.

  4. Create a new JavaFX project using JDK and JavaFX 17.0.2+.

    • Select Maven for the build system unless you know and prefer Gradle.

  5. Do not set VM arguments, you don’t need them.

    • Adding modules via the --add-modules VM arguments is unnecessary when you have a valid module-info.java file.
    • The --module-path is still required so that the modules can be found, but Idea will provide the correct path for your modules automatically when it recognizes the modules through your Maven dependencies.
    • So you don't need to explicitly define the --module-path VM argument yourself for a Maven based build (that would be difficult to do anyway because the modules are all downloaded to different directories in your local maven repository).

  6. Test it works following the Idea create new JavaFX project execution instructions.

  7. Add additional modules one at a time by adding their maven dependency to pom.xml and the requires clause to module-info.java.

  8. Test between each addition by building and running the project, to ensure you haven’t broken anything.

  9. Copy your original source code into the appropriate package directories under the new project source directory:

    src/main/java

  10. Place resources in:

    src/main/resources

    following the Eden resource location guide.

  11. Fix any errors, ensure everything compiles and runs, then test it.
