soot.SootResolver$SootClassNotFoundException: couldn't find class: kotlin.Metadata (is your soot-class-path set properly?)

Question

I am trying to use soot to analyze the kotlin project. I have written a HelloWorld.kt script and compiled it. I bring the snippet of code bellow:

fun main(args: Array<String>) {  
   println("Hello World!")         
}

However, when I use soot to generate the CFG of its .class file, I get this errors：

soot.SootResolver$SootClassNotFoundException: couldn't find class: kotlin.Metadata (is your soot-class-path set properly?)

I just executed the following commands:

java -cp sootclasses-trunk-jar-with-dependencies.jar soot.tools.CFGViewer -cp . -pp Helloworld

I can not find what is my mistake. Could you please help me?

Answer 1

you would have to add kotlin jars into the soot's classpath to make it work

-cp .:$HOME/Downloads/kotlinc/lib/kotlin-stdlib.jar:$HOME/Downloads/annotations-23.0.0.jar -pp

PS annotations could be downloaded from https://mvnrepository.com/artifact/org.jetbrains/annotations
