Using GraalVM and NetBeans 12.5 as a replacement for Nashorn capabilities within the Ant framework

After coming back to upgrade my Java and FX code, I'm facing issues with building due to the absence of Nashorn. I am stuck on how to configure graalvm to replace Nashorn in compatibility mode for processing build JavaScript.

Despite suggestions to switch from ANT to Maven, I prefer sticking with my current setup. Can anyone guide me through making necessary changes in Netbeans 12.5 to ensure that JavaScript works seamlessly again?

The complexity of GraalVM is overwhelming for my current needs, so any specific help would be greatly appreciated!

Thank you!

Even though Nashorn was removed from JDK 15, it continues to thrive as a standalone OpenJDK project, much like JavaFX.

To seamlessly integrate standalone Nashorn into your Ant build, simply add the Nashorn JAR file as a dependency. This minimal change will keep you moving forward without any hassle.

If you prefer not to place it in the Ant lib directory, consider including it within your project and then utilizing <classpath> or <classpathref> in the <script> tag to specify its location.

You can acquire the JAR from Maven Central; just make sure to review the POM file for any additional dependencies (such as ASM JARs) that may be required. If you are using a dependency manager like Gradle or Maven, they will handle these automatically.
