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?

[Ben Madore]

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

[Ben Madore]

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

[Thomas]

sure good luck:-)

[Ben Madore]

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

.java in src/main/kotlin does not.

[Ben Madore]

solution: just stick everything in src/main/java
