Gradle run: getClass().getClassLoader().getResource() return Null

I'm trying to import a file to use in my simple Java project, I'm currently using IntelliJ as IDEE and Gradle to build the project.

Problem:

When I try to check if the program load the resources using URL url = getClass().getClassLoader().getResource(filePath); function, passing "src/main/resources/File" as argument, it work fine, as I build the application (using Gradle) and run it via IntelliJ. However, when I try to get it work with grade run via terminal, the task FAIL because it can't find the resource file, as the function return Null. Here is my path tree:

                            └── progettofinaledatemplate->resources files

Sorry If I repeated an already existing topic, but I can't find any solution.

What I tried:

• Verified the presence of the file in the filepath
• rebuilt the project via Build > Rebuild Project
• used an absolute path
• tried to verify that grade included the resources with:

sourceSets {
    main {
        resources {
            srcDir 'src/main/resources'
        }
    }
}

Solution that worked with my Application:

After hearing the many helpful tips, I removed the nesting of the resource files, given "Tracciato3.txt" the file name and X the class I used, I moved the "Tracciato3.txt" file from:

src/main/resources/it/uni/cs/name/progettofinaledatemplate/Tracciato3.txt

to

src/main/resources/Tracciato3.txt

now if I use

URL url = X.class.getClassLoader().getResource("Tracciato3.txt");

it doesn't return null, instead It get the correct URL.

It worked for me, so I hope this will be helpful
