How to Include script.js in Javadoc with Ant for JDK 17?

Introduction If you're using Ant to generate Javadocs for your Java applications, you might run into issues like missing resources, such as the script.js file needed for proper documentation functionality. In this article, we will address how to correctly include the script.js file in your Javadoc output and explore why it might not be appearing in your documentation folder after using the task. This guide is tailored for those using JDK 17 and Ant 1.10.14. Understanding the Issue When generating documentation with Ant using the task, additional resources required by the Javadoc HTML pages, such as JavaScript files, are generally not included in the output directory. This typically leads to issues where the generated HTML does not function as expected due to missing scripts, like the script.js file from the official Java documentation. Why is script.js Missing? The reason for the missing script.js file could be due to a few factors: Ant Configuration: The Ant build file may not be copying secondary resources appropriately after the Javadoc generation. File Path Issues: The output destination where script.js should be placed might not be correctly defined.
