A modern programming language that makes developers happier.

kotlinlang

i’m sure i’m just doing something silly, but i’ve got a spring boot project containing:

```src/main/kotlin/com/foo/Blah.java
src/main/kotlin/com/foo/bar/WebController.kt```
WebController instantiates and uses a Blah. at compile time, no issues. when i start the app with `gradle bootRun` - at runtime i get:

`java.lang.NoClassDefFoundError: com/foo/Blah`

i shouldn’t _have_ to do anything special to make sure the java classes are on the classpath, right?

ahhh, it looks like by default the java does _have_ to be under `src/main/java`? This documentation appears to be misleading: <https://kotlinlang.org/docs/mixing-java-kotlin-intellij.html#adding-java-source-code-to-an-existing-kotlin-project>

Would agree with this assumption. And also wonder that the error is showing com/foo/bar/Blah, while your class is in com/foo/ directory

sorry, i obfuscated the actual paths, and fatfingered it:D

so, `.kt` and `.java` in `src/main/java` work just fine by default.

`.java` in `src/main/kotlin` does not.

solution: just stick everything in `src/main/java`
