Problem description: When using the Kotlin compiler (kotlinc) of any version from the command line (not IntelliJ IDEA, but a separate folder with a .bat file), and when specifying multiple libraries (.jar files) using -cp or -classpath, I get the error: "source entry is not a Kotlin file". The problem only occurs when using multiple libraries; if I use a single library, everything works fine.

Environment: windows: cmd, shell, or Runtime.getruntime().exec() in IntelliJ IDEA

Steps to reproduce: I have tried different delimiters (:,;), as well as different cmd/shell/Runtime.getruntime().exec(), tried to use wildcards(*) instead of listing.

Command in shell/cmd:

C:\Users\MSI\Desktop\COMMANDLINE\kotlin-compiler-1.9.0\kotlinc\bin\kotlinc.bat -cp C:/Users/MSI/Desktop/COMMANDLINE/libs/* C:\Users\MSI\Desktop\bbb\kotlin.kt -include-runtime -d C:\Users\MSI\Desktop\bbb\gigga.jar

Code in IntelliJ IDEA:

val command = ProcessBuilder(
    "C:\\Users\\MSI\\Desktop\\COMMANDLINE\\kotlin-compiler-1.9.0\\kotlinc\\bin\\kotlinc.bat",
    "-cp", "C:/Users/MSI/Desktop/COMMANDLINE/libs/*",
    "C:\\Users\\MSI\\Desktop\\bbb\\kotlin.kt",
    "-include-runtime",
    "-d", "C:\\Users\\MSI\\Desktop\\bbb\\gigga.jar"
)
            val start = command.start()
            val code = start.waitFor()

I want the code to be compiled with all the libraries

  • I'm not sure if Kotlin supports the syntax for including multiple jars from a directory. I know Java does, but not sure about Kotlin. Have you tried using quotes around the directory and asterisk, i.e. -cp "C:/Users/MSI/Desktop/COMMANDLINE/libs/*"? Commented Sep 5 at 11:07
  • Ok, it looks like Kotlin doesn't support it: discuss.kotlinlang.org/t/… Commented Sep 5 at 11:22
  • @k314159 this helped! true * in "" still doesn't work but listing through ; in "" works. This is completely not obvious and it needs to be spread. Thank you so much! Commented Sep 5 at 15:08
