The root exception is : "Service ClassMappingTypeService not found".
If you look at the source code (https://github.com/Litote/kmongo/blob/master/kmongo-shared/src/main/kotlin/org/litote/kmongo/service/ClassMappingType.kt#L26), you can see that ClassMappingTypeServices are loaded using ServiceLoader mechanism : it seems you have a classpath issue.

Checks that you have this file in your classpath: https://github.com/Litote/kmongo/blob/master/kmongo-jackson-mapping/src/main/resources/META-INF/services/org.litote.kmongo.service.ClassMappingTypeService

[LarsArtmann]

It is already in the jar file

[zigzago]

Please provide a reproducible test case

[LarsArtmann]

The Velocity version of (AstrideUG/MC-Data@5d33b74) (the Jar (in the Zip))
in the plugins folder of a Velocity Server version 1.0.0

@LartyHD IS there other lib in the classpath? When I try to use the jar, I have this exception :

java.lang.ClassNotFoundException: org.bson.codecs.pojo.annotations.BsonId

Because there is no mongo java driver class

And If I add the bson-3-10-2.jar in the classpath( where there is already only MCData-Velocity-1.0.0.jar + kotlin runtime), this code returns null as expected:

class A(val r:String)

/**
*
*/
fun main() {
println(ClassMappingType.findIdProperty(A::class))
}

// -> print null - no error

[LarsArtmann]

@zigzago sorry i forgot the lib 😞
You can get it here: https://workupload.com/file/wd3ZaXQG

@LartyHD Still ok with the additional jar - and still no bson dependency in it

By the way there is no class org.litote.kmongo.jackson.JacksonClassMappingTypeService in the two jars you provide - and it's a problem ;)

[LarsArtmann]

@zigzago i added the missing class and bson to the jar.
I had this exeption in my test: http://prntscr.com/oyf0rl
I found this line: https://github.com/Litote/kmongo/blob/master/kmongo-shared/src/main/kotlin/org/litote/kmongo/service/ClassMappingType.kt#L38 an i don't know whats the problem is, again 😬

[zigzago]

Sorry but I have not more time to expore a particular case that look like a class path issue
