Why is `class.getResource()` returning null despite having a resource in the project?

Identifying the Null Response from class.getResource

Despite utilizing the class.getResource() method to retrieve the URL of a resource, the returned value is often null. This issue can arise due to various reasons, requiring an investigation of the underlying cause.

Fortunately, assistance is available for resolving this issue. The following answer provides a practical solution:

Solution:

For those utilizing Intellij Idea, it is essential to verify the Resource Patterns settings within the project. These settings govern the extensions recognized as resources by the Java compiler. If an extension used within a resource does not align with any of the designated patterns, the class.getResource() method will yield null.

Addressing the Issue:

1. Access the Intellij Idea settings.
2. Navigate to Build, Execution, Deployment.
3. Select the Compiler tab.
4. Examine the Resource Patterns section.
5. Ensure that the extension of the resource you are attempting to access is included within the specified patterns.

By incorporating this solution, you can resolve the null response issue and effectively retrieve the URL of the desired resource.
