How to share resources between test and main?

Question

I'm working on a web application.

This is my project structure

src/
├── main
│   ├── java
│   ├── resources
│   └── webapp
└── test
    ├── java
    └── resources

In my tests I want to call a method from a class in java which uses a file in resources.

So I want to know how to share my resources between main and test?

I don't want to copy files to test-resources every time I edit them.

I tried SymLink but got an error 'Can't copy to test-classes because file does not exist.`

And this is how I access a resource in case it matters

class.getResourceAsStream("/data.yml");

EDIT

So, apparently Maven do share resources between main and test by default but it's not the case here.

When I build I can see my resources from main under target/classes but nothing in target/test-classes.

Files present in main are visible in test.

So you can put resources on the main tree if necessary for both tests and main.

If the resources are necessary only for the test put them on the test subtree.
