MapDB ClassNotFoundException: kotlin.jvm.internal.Intrinsics

Question

I am trying to run a simple mapdb example, but get the error:

    Exception in thread \"main\" java.lang.NoClassDefFoundError: kotlin/jvm/internal/Intrinsics         


        

Answer 1

Either kotlin-runtime has to be in classpath and verify with $ echo $CLASSPATH.

Or you have to add kotlin-runtime to maven and then assemble inside the jar itself with mvn compile assembly:single,

    org.jetbrains.kotlin
    kotlin-runtime
    1.1.3
    compile



    org.jetbrains.kotlin
    kotlin-stdlib
    1.1.3
    compile

which need to be attached to artifact as well and can be done with assembly-plugin.

    
        maven-assembly-plugin
        
            
                
                    event.handlers.InventoryEventHandler
                
            
            
                jar-with-dependencies
            
        
    

you can verify the kotlin-runtime is added to jar by

$ jar -tf target/amz-wavelength-1.0-SNAPSHOT-jar-with-dependencies.jar | grep kotlin-runtime
META-INF/kotlin-runtime.kotlin_module

or

$ jar -tf target/amz-wavelength-1.0-SNAPSHOT-jar-with-dependencies.jar | grep "kotlin/jvm/internal/*"
