Setting Your Preferred JavaFX Version in Scene Builder

As a JavaFX developer, you might have encountered an annoying problem while working with Scene Builder. After setting your desired JavaFX version, you notice that Scene Builder keeps overwriting it to a different version each time you make changes. This can lead to warnings when you run your application, causing frustration and halting your development progress. In this post, we'll explore how to fix this issue so that Scene Builder recognizes your preferred version of JavaFX.

Understanding the Issue at Hand

When you work on a JavaFX project, you may notice warnings regarding version mismatches, especially if you are not using the latest JavaFX version. For instance, you might be using JavaFX version 11.0.2, but Scene Builder reverts back to version 15.0.1 every time you edit your .fxml files. This not only leads to compatibility warnings but can also complicate your development process.

Example of the Warning

Here’s a snippet of the warning you may encounter:

The main problem here is that Scene Builder checks the JavaFX version from your project settings, and if it’s not set correctly, you will continue to receive this frustrating prompt.

Solution to Set Your Preferred Version

Fortunately, there’s a straightforward solution to this issue. By editing Scene Builder's configuration file, you can set your preferred JavaFX version, preventing it from reverting back to the undesired one. Here's how you can do it:

Step 1: Locate the Configuration File

Find the installation directory of Scene Builder. Typically, it is located in:

Step 2: Modify the Configuration Settings

Open the SceneBuilder.cfg file in a text editor of your choice.

Look for the section labeled [JavaOptions]. If it doesn’t exist, you can create it.

Add the following line to specify your desired JavaFX version:

Explanation of the Configuration Option

By setting javafx.version to null, Scene Builder will not check for any specific JavaFX version. This means that even if you open the .fxml file with a different JavaFX version, you won’t receive any warnings.

Optional Adjustment: If you prefer to lock it to a specific version, replace null with your desired version (e.g., 11.0.2).

Step 3: Save and Restart

Save the changes in the configuration file.

Restart Scene Builder to apply the new settings.

Conclusion

By following these steps, you can effectively set your preferred JavaFX version in Scene Builder and prevent it from being overwritten in future edits. This change will help you maintain compatibility with your development environment while minimizing distractions from version warnings.

Take control of your development workflow and keep your projects running smoothly! If you encounter more issues or have questions, feel free to explore community forums or contact JavaFX experts for further assistance.

Happy coding with JavaFX!
