How to generate exe?

[meoowe]

Hello, how can I generate a Windows executable? Do I make a JvmJar and then use a tool to generate an exe, or is there another way that I am not aware of?

Heya @meoowe 👋🏻

You can use the Gradle Command packageJvmWindowsApp :)

Here are the commands for the following targets: (JVM & JS)

You'll find the built project in <your-module>/build/platforms.

Below you'll see it within an multi-module project (client, server, shared):

Be aware, that you need to ship the entire folder (jvm-win32 in this case) for it to work :)
(You can just rename it tho :))

Error message - Parameter specified as non-null is null: method korlibs.korge.gradle.targets.jvm.JvmKt.getMainJvmCompilation, parameter <this>

this happens during the packageJvmFatJar task while building.
sorry for disturbing you again

I just found out the cause of your error :D

In your gradle.properties file, delete the last two lines like following:

After another Gradle Re-Sync you should be able to build your app :)

Something within packageJvmFatJar seems to be incompatible with the Gradle Cache 😅.

I can reproduce this with the "Hello World" Example :).

Funnily enough I used the "Hello World + KTor"-Template for my project, which still runs on an older version, and upgraded Korge myself.
And those two lines are not present in that template, which is why I was able to build my project without any problems :o

[meoowe]

it worked! thank you so much! you are the most helpful person alive.

Nice 🎉
Happy to help :D

Sorry to disturb you yet again but, whenever I package my project using packageJvmWindowsApp or any other way, I can't see any sprites or images on anything besides the starting screen. If I use runJvm or runJs it works. I have three different scenes: a TitleScreen, an options scene and a GameScene. On the options scene, I can not even see the UI buttons. The TitleSceen works perfectly fine. On the GameScene I can see the UI buttons. Can

Haha don't worry about it :)
I'm here to help :D

I looked at your Game (The repository is public on your GitHub profile :b) and I found your problem:
The images/sprites don't load because you have some typos when accessing some ressources 😅

E.g:
resourcesVfs["img/dog.png"] should be resourcesVfs["img/dog.PNG"] (Notice the upper-case "PNG")

This is some weird behaviour from Korge tho, since it seems to be case insensitive when running using runJVM and then becomes case sensitive after packaging 🤔

And in your case because it couldn't find the "house"-Sprite, it aborted the entire sceneMain function 😅

[maik-mursall]

IMO Korge should have some better error-handling in this case, since this was pretty tricky to find you 😅

[maik-mursall]

One thing that would eliminate this issue is using KR instead of strings for accessing your ressources :)
This is an generated object, which holds your ressources. It gets generated during the build process.

E.g
Instead of resourcesVfs["img/house.png"].readBitmap() you can just call KR.img.house.read().

The object follows your ressource structure.
If you add any ressource you have to re-build the app for KR to get regenerated :)

I hope with that you won't encounter these weird issues anymore :D

[meoowe]

Thank you again! I think the upper case .PNG is because it came from an Apple device.
I have never actually used KR so this is all new to me.

It seems that it triggered this: #599
When using runJvm, maybe it is using resources from the local filesystem that is case insensitive on windows, while packed it is inside a .jar, where it might be case-sensitive.
