Beschreibung

Is there an existing issue?
Build info
  • ObjectBox version: 5.0.0
  • OS: Windows 10
  • Device/ABI/architecture: x64
Steps to reproduce

I am building a KMP project with ObjectBox. When I run the jvmApp module directly (e.g., from the IDE), the ObjectBox .dll file is found and loaded correctly.

However, when I build a distributable package for deployment (e.g., using jpackage), the .dll file seems to be missing from the final package, causing it to fail at runtime.

What could be the problem?

(I apologize for asking this again. I posted this on StackOverflow, but since I haven't received a response yet, I'm posting it here as well.)

Expected behavior

Create objectbox-jni-windows-x64, when the installer installs the executable.

Actual behavior

The .dll file is not included when the installer installs the executable.

Erste Schritte

  1. Lies das ganze Issue und danach den Beitragsleitfaden des Projekts.
  2. Schreib ins Issue, dass du es übernimmst — das erspart doppelte Arbeit.
  3. Forke das Repository und arbeite in einem Branch.
  4. Öffne einen Pull Request, der die Issue-Nummer nennt.

Rechercherichtung

Beginne mit build.gradle.kts in :jvmApp und :data-jvm, und untersuche anschließend die nativeDistributions-Konfiguration von Compose Desktop sowie das Ressourcenverzeichnis der installierten Anwendung. Erzeuge den Windows-Paket-Build erneut und vergleiche ihn mit der direkt ausgeführten JVM-Anwendung, wobei UnsatisfiedLinkError und der Speicherort von NativeLibraryLoader als erste Hinweise dienen. Als erledigt gilt die Aufgabe, wenn das installierte Paket objectbox-jni-windows-x64 enthält und die installierte Anwendung ohne den Fehler der nativen Bibliothek startet.
