Start by using the official jdk distribution and not Temurin to rule that part out

[Michael Paus]

Temurin is not the problem. I am using that too and it works. To me it looks as if you have forgotten to eject the DMG drive after an installation attempt which is now blocking the build of a new one. Just a guess from the error message but I once stumbled over that myself too.

[Ch8n]

I will give that a try @Michael Paus.

[Ch8n]

@Kirill Grouchnikov I tried every jdk version avaiable on IntelliJ nothing worked.

@Michael Paus how can i eject DMG cant find anything related to it.

[Michael Paus]

When you double-click on a DMG file it gets mounted as a file system like when you insert an USB stick. With the Finder you can eject that. In the past I had the problem that when the DMG file was still mounted, jpackage could not create the same DMG file again. The error message /usr/bin/hdiutil, attach ... is hinting in this direction but without knowing more details it is just a guess.

[Ch8n]

@Michael Paus I checked with diskutil list command nothing was mounted still I'm getting error any more suggestion you can provide?

[Ch8n]

@theapache64 buddy you know anything regarding this

[theapache64]

@Ch8n Sorry mate. I haven’t tried packaging dmg. I use JAR via packageUberJarForCurrentOS
