Using vpl-junit-0.8.jar with Kotlin classes fails with java.lang.NoClassDefFoundError

[frankneumann]

Hi,

I would like to use vpl-junit-0.8.jar with Kotlin classes as the latest VPL version included support for Kotlin.

When I evaluate the unit tests, I get the following error:

java.lang.NoClassDefFoundError: kotlin/jvm/internal/Intrinsics
--|>
<|--
at: FractionKt.invert(Fraction.kt)

which means that the Kotlin STD Lib is missing, although I included it in class path:

search for Kotlin standard library and include it in class path

kotlin_std_lib=/opt/kotlin/lib/kotlin-stdlib.jar
if [ -f $kotlin_std_lib ] ; then
CLASSPATH=$CLASSPATH:$kotlin_std_lib
fi

and

cat common_script.sh > vpl_execution
echo "export CLASSPATH=$CLASSPATH" >> vpl_execution
echo "timeout $vpl_junit_timeout java -jar $vpl_junit_version $@" >> vpl_execution
chmod +x vpl_execution

I attached all files.

Any hint on that very welcome.

Thanks for the suggestion!
I will test this in the near future and merge it into the codebase if it does not interfer with the current functionality

Thank you for your reply: Do you have any idea how a workaround for me could look like?
I added the Kotlin STD lib to the class path and assume that your JAR should respect the settings of the class path.

Since i am no Kotlin specialist, i have to look up how things are working there.
Nevertheless, it uses the JVM, and there we can inject the classpath via the --classpath option.

Does your solution work on your machine ?

I found a workaround: I included the content of the Kotlin STD lin inside of your VPL JAR file and everything works perfectly.
I still have no clue why setting the classpath does not help.
Thank you for your help and for your lib - it is very helpful.
May be you find a more elegant solution.
