Kotlin project problem

[davidpodhola]

Following the instructions to add project test, I get this warning

> Configure project :
Gradle now uses separate output directories for each JVM language, but this build assumes a single directory for all classes from a source set. This behaviour has been deprecated and is scheduled to be removed in Gradle 5.0
        at build_6fro0prhrczp7fhe7kzk924yq$_run_closure2$_closure13$_closure16.doCall(/home/david/dev/osgi-starterkit/build.gradle:89)
        (Run with --stacktrace to get the full stack trace of this deprecation warning.)

> Task :test:bndJar
-----------------
Warnings
000: test: Unused Export-Package instructions: [software.hsharp.demo*] 
001: test: The JAR is empty: The instructions for the JAR named test did not cause any content to be included, this is likely wrong

I also changed the kotlin version in the build.gradle to

ext.kotlin_version = '1.2.21'

The resulting JAR is really empty so the servlet does not work.

Hey @davidpodhola, your /bin folder looks empty in the screenshot, have you tried to compile before building the jar out of the *.class in the /bin? I will double check with a Kotlin demo project later. I didn't use BND plugin in any way so no worries there.

Hi, thanks a lot.

When I do

gradle :test:build

I get again

Warnings
000: test: Unused Export-Package instructions: [software.hsharp.demo*] 
001: test: The JAR is empty: The instructions for the JAR named test did not cause any content to be included, this is likely wrong

BTW

• Kotlin classes ARE generated in /subprojects/test/classes/kotlin/main folder.
• when compiling from IDEA, Kotlin classes are generated in the /subprojects/test/bin/ folder. The get deleted as soon as I run the build from the command line
