how would I go about loading an image from a test directory's resources in kotlin? Tried it using the class loader but ran into a NPE:

var byteArray = this::class.java.classLoader.getResource("abc.jpg").readBytes()

[Jonathan Olsson]

Not sure if the folder should be named resources, not res?

[Cath]

not sure it matters, it's marked as resource directory and the one I use for the src dir has the shortened name too

[Timo Gruen]

What build system are you using? Anything like Gradle?

Generally speaking you can use:

var byteArray = this::class.java.classLoader.getResource("/abc.jpg").readBytes()

(Note the absolute path of the resource)

[Timo Gruen]

Generally speaking the res directory should be named resources , which is the convention for such directories. If you are using gradle, this is the one being picked up by gradle while building and running your code.

[Cath]

Yea, Gradle w the Kotlin DSL. I'll try that again but I think I experimented with both to no avail. It's a KMM project if that makes a difference, currently only working on the androidApp module though

[Timo Gruen]

So test
1. Having a absolute path (/abc.jpg )
2. Rename res to resources
If its still not working, just ping me and we ll see if I can help you somehow.

Oh actually changing the name from res seems to have fixed it, without absolute path. Thanks!

Without the starting slash in the path it will be relative to the class doing the lookup, so e.g. if you are loading from com.example.app.MyClass then the file would need to be at resources/com/example/app/abc.jpg
