[SOLVED] Strange Scala Error when Using Scala Reflect

Strange Scala Error when Using Scala Reflect

I added a dependency to the scala reflect library version 2.11.8 to one of my existing project such that I could use TypeTag's but strangely I face some error when running. Here is my error:

Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home/bin/java (0x10a3ab4c0) and /Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home/jre/lib/libinstrument.dylib (0x10b4ce4e0). One of the two will be used. Which one is undefined.
Exception in thread "main" java.lang.AbstractMethodError: Method com/my/csvparser/CSVParser$.scala$App$_setter_$executionStart_$eq(J)V is abstract
    at com.my.csvparser.CSVParser$.scala$App$_setter_$executionStart_$eq(CSVParser.scala)
    at scala.App$class.$init$(App.scala:44)
    at com.my.csvparser.CSVParser$.<init>(CSVParser.scala:13)
    at com.my.csvparser.CSVParser$.<clinit>(CSVParser.scala)
    at com.my.csvparser.CSVParser.main(CSVParser.scala)

Did anyone face a similar issue? My Scala version is 2.11.8

Solution

It worked for me by removing object class extending App and putting all piece of code into main method means doing

object Test {
   def main(args: Array[String]): Unit = {
  }
}

Instead of

object Test extends App {
       
    }

I am still not sure why it just worked as I am also new to scala world.
