I have a Multiplatform app with desktop(compose), Android app and web. When I run the desktop module in windows directly from Idea (Play Button), then the JVM application opens. But, if I run

:packageMsi

, install

.msi

and try to run the

.exe

file, then it is not opening. It doesn't even throw any error. How to fix this and how to check logs of an executive application?

Does it print anything when opening the .exe from CMD or Powershell?

Nope. I tried

FILE.exe > output.txt

as well And the txt file came out blank

maybe something with the packageMSI that needs additional config? Maybe it isn't finding your main class

Did you try the gradle targets runDistributable or runReleaseDistributable? This might provide some more insight into what’s going wrong.

It's unable to find my class Main.kt

Kotlin automatically creates a class to hold your

main()

based on the file name. If you have your

main()

in

Main.Kt

kotlin will generate a

MainKt

class for the JVM

mainClass = "MainKt"

Note the “Kt” in the name.

ah. Just found out the same. It was "Main.kt" earlier (I guess intellij project template has written it like that). And I tried changing it to Mainkt. But overlooked the capital K Thanks everyone. It's fixed now.

Apps just not appearing if the JVM fails to start or if an exception escapes the main thread is an annoying issue. If you use Conveyor instead of the packageMSI task, that is resolved and an error dialog with the exception message and top stack frame will appear, you can also put apps into console mode easily.
