with updated `build.gradle.kts` works but not with folder.

for example, `/src/main/kotlin/example/Example01.kt`  
I got this message

```auto
$ ./gradlew run -Papplication=example.Example01

Does the first line of `Example01.kt` look like

```auto
package example

```

? For me it works.

```auto
cd src/main/kotlin
mkdir example
cp TemplateProgram.kt example/Example01.kt
vi example/Example01.kt
# make first line equal to `package example`, change color to GREEN
cd ../../../
./gradlew run -Papplication=example.Example01

```

How does `Example01.kt` look like?

hmm? just change the color GREEN and others are totally same.

```auto
import kotlin.math.cos
import kotlin.math.sin
import org.openrndr.application
import org.openrndr.color.ColorRGBa
import org.openrndr.draw.loadFont
import org.openrndr.draw.loadImage
import org.openrndr.draw.tint

fun main() = application {
    configure {
        width = 768
        height = 576
    }

    program {
        val image = loadImage("data/images/pm5544.png")
        val font = loadFont("data/fonts/default.otf", 64.0)

        extend {
            drawer.drawStyle.colorMatrix = tint(ColorRGBa.WHITE.shade(0.2))
            drawer.image(image)

            drawer.fill = ColorRGBa.GREEN
            drawer.circle(
                    cos(seconds) * width / 2.0 + width / 2.0,
                    sin(0.5 * seconds) * height / 2.0 + height / 2.0,
                    140.0
            )

            drawer.fontMap = font
            drawer.fill = ColorRGBa.WHITE
            drawer.text("EX01", width / 2.0, height / 2.0)
        }
    }
}

```

I have no idea, what I missing ? 😕

You are missing the first line: `package example` 🙂

If the file was opened in Idea it would suggest you to fix that automatically.  
If the folder was `example/bla` then you would need `package example.bla` .

btw I upload vscode tasks.json to [repo](https://github.com/icq4ever/openrndr-vscode).  
still need to update how to run subfolder codes, build excutable binary. etc.

When you are comfortable with your setup it would be amazing if you could write a short post `Using OPENRNDR with vscode` (and you can edit the post any time if you want to improve it 🙂 ). Probably some users would like that 🙂

Great work! Thanks for sharing that repo!
