Scala getClass.getResource() returning null

Question

I have this code:

val url: URL = getClass.getResource(\"com/mysite/main/test.fxml\")

and it always returns null (or Unit

Answer 1

You have three options:

• take advantage of relative path to your current package (where Test.class is):

  getClass.getResource("test.fxml")
  

• you can use absolute path:

  getClass.getResource("/com/mysite/main/test.fxml")
  

• or load through the ClassLoader (note that it always start from root):

  getClass.getClassLoader.getResource("com/mysite/main/test.fxml")
  

In IntelliJ IDEA, make sure you have added ;?*.fxml to the:

Settings (Preferences on Mac) | Compiler | Resource Patterns.

Answer 2

Late answer but I just had this same problem. The root cause was an incorrect rootProject.name entry in my settings.gradle. Once I fixed that, cleaned, and rebuilt my resource were able to load using getClass().getResource(). Hopefully that helps somebody.

Answer 3

If it does not work, you can try with ClassLoader:

ClassLoader.getSystemResource("filename").getPath

The filename should be in the same directory layer

Answer 4

Possibly it's not being copied to the bin/ directory from the src/ directory? This happens on recompilation, but if you drop it into the src/ directory after the program is already compiled, the IDE won't know.
