So everything was working just fine before the reinstall. I pushed to git naturally then I reinstalled my OS. After the reinstall, when I try to run the JavaFx application, I get the IllegalStateExceptionL: Location is not set

Is there any reason why this is happening? It worked before and now it isn't. My folder structure is like this:

src:
   main:
       java:
           com.package:
                      Launcher.java
       resources:
           com.package:
                      main.fxml

And this is how I get the resource in my Launcher.java class:

  URL resource = getClass().getResource("main.fxml");

What I've tried:

When I sout the resource, (obviously) null is returned. I have also checked and verified that my resources is marked as the resources root in Project Structure.

I have also tried changing the path to /main.fxml but this doesn't work also. I feel like I shouldn't be even changing the code and maybe Intellij is missing something? But anyways I'm just confused as to why this is happening all of a sudden. Not sure if this is a duplicate since its a common error but I want to know why it just stopped working.

Any help would be appreciated

(The only thing that's changed from the previous set up is the Java version. I was on JDK14 previously and I'm using 15 now.)

The stacktrace is :

    Check the content of the build folder. – James_D Oct 28 '20 at 13:03
  • Please share the stacktrace. Also, we don't know what "the" JavaFX application is so relevant code would help. – Michel Jung Oct 28 '20 at 14:01
  • @James_D the build folder shows the file `build -> resources -> main -> com -> package -> main.fxml` – carlo_webber124 Oct 28 '20 at 15:51
  • @MichelJung I made an edit with the stacktrace. As for the code, its just the main Launcher for my application. I can show the class too but its just your regular JavaFX FXML loading for the `main` method – carlo_webber124 Oct 28 '20 at 16:01
  • Is your project a Java module? If so, `getClass().getResource("main.fxml")` might not work (I can't explain why). And is your project started via Gradle? – Michel Jung Oct 28 '20 at 16:11
  • The build looks wrong to me. `Launcher.class` should be in the same folder (in the build/output structure) as `main.fxml`?. – James_D Oct 28 '20 at 16:41
  • @MichelJung yes it is a Gradle modular project. It was working before though – carlo_webber124 Oct 28 '20 at 16:51
  • @James_D Anything I can do to rectify the build? – carlo_webber124 Oct 28 '20 at 16:53
  • I'd clean and rebuild it first. Then check gradle settings (I'm not a gradle user). – James_D Oct 28 '20 at 16:55
  • Just tried that, no dice. Are you on Maven? I can try switching to it and see if it compiles – carlo_webber124 Oct 28 '20 at 16:58
  • What version of Gradle are you using? Can you share your `build.gradle[.kts]` file? And to clarify, does your code have a `module-info.java` file? – Slaw Oct 28 '20 at 21:04
  • @Slaw here's the `build.gradle` file from the [repo](https://github.com/kawaki-san/DigitalAssistant/blob/master/build.gradle). And yes, I have a `module-info.java` file. Grade is `gradle-6.5.1-all` – carlo_webber124 Oct 28 '20 at 21:26
