How do I access resource files in Java (Intellij)?

I can't seem to get my head around accessing resource files, when the resources-marked folder 'resources' is not inside the source-marked folder 'java'.

Here is my project structure (which follows Maven structure, but I still like it):

|src 
|-main
|--java (marked as sources folder)
|--|projectname
|--|-main.java
|--|-Class2.java
|--|- ..
|--|-Classx.java
|--resources (marked as resources folder)
|--|config.properties
|--|images

this is how it looks in IntelliJ

I have applied every possible change to the following line, still I can't seem to load the config.properties file or any other file from the resources folder.

getClass().getResource("config.properties");

which is being called in the main class. This should be working right? Why doesn't it though?

How do I access a resource with this project structure?

Much love, Jiefu

edit 1: after same testing, it seems to have to do with directories being between the marked source folder and the content root (which is parent of src here) I don't yet know why this is or how to get around it...

Solved: turns out, deleting the output folder and restarting IntelliJ fixes it. I had to do it twice though... Weird.

I was wrapping my head for two days about this and this is what it was ^.^

Your class is in package projectname, so the code is looking for the resource file projectname/config.properties, but the file is not there.

To look for resource file config.properties, use:

getClass().getResource("/config.properties");

as documented in the javadoc of getResource().

And remember, the resource may not be a file on the file system, so don't use e.g. File to access it. To read the content of the resource, use getResourceAsStream() instead.
