How to use jssc in Kotlin? - kotlin

Question

I'm developing a program to measure weight by connecting a PC with an electronic scale.
I'm developing a language with Kotlin, and I'm trying to refer to Java's library, JSSC.
but I don't know what to do because I get a reference error every time.
The development tool is IntelliJ from JetBrain.
import jssc.SerialPortList
object Main {
#JvmStatic
fun main(args: Array<String>) {
val portNames = SerialPortList.getPortNames()
for (i in portNames.indices) {
println(portNames[i])
}
}
}
The top one is a kortlin and the bottom one is a java. I used the translator of the development tool.
import jssc.SerialPortList;
public class Main {
public static void main(String[] args) {
String[] portNames = SerialPortList.getPortNames();
for(int i = 0; i < portNames.length; i++){
System.out.println(portNames[i]);
}
}
}
Java executed, but Kotlin was unable to compile due to errors such as
Unresolved reference:jssc
Unresolved reference: SerialPortList
I'm not sure how to avoid these reference errors, so I'm asking for advice.
Please give me a good answer.

Answer 1

It looks like you want to use java-native/jssc library. The error Unresolved reference is a compilation error. Your code does not have access to the class jssc.SerialPortList. You should follow the instructions on the Github page and add the dependency in your maven or gradle config, or manually add the jar dependency into your Intellij Idea.
