Hello Alex, thank you for coming back. We now have four different cases just for the second build step (appimage->deb). Let me first give you an overview:
My Desktop (OpenJDK 16): My Command, Your command Github (OpenJDK 17): My command, Your command On Github I started using OpenJDK11, then switched to 16 and finally to 17. In respect to my build they all seem to behave the same. So I will give the status on all four of the combinations. And btw I use Gradle to trigger command lines which impacts a bit the log output but otherwise should not matter. --My Desktop, my command:-- Starting process 'command 'jpackage''. Working directory: /home/hiran/NetBeansProjects/settlers-installer/app Command: jpackage --app-image build/app-image/SettlersRemake --dest build/distributions --resource-dir build/resources/jpackage Successfully started process 'command 'jpackage'' :app:jpackagePhase2 (Thread[Execution worker for ':' Thread 3,5,main]) completed. Took 12.313 secs. This one runs reliably. I was a bit annoyed that the appdir directory is one level more than for build step 1 (input->appimage) - but maybe that is exactly because I did not specify --name. After all I have a Debian package that I can verify and install. --My Desktop, your command-- Starting process 'command 'jpackage''. Working directory: /home/hiran/NetBeansProjects/settlers-installer/app Command: jpackage --app-image build/app-image/SettlersRemake --dest build/distributions --resource-dir build/resources/jpackage Successfully started process 'command 'jpackage'' :app:jpackagePhase2 (Thread[Execution worker for ':' Thread 3,5,main]) completed. Took 12.313 secs. I added --name as you suggested. It seems I still need to specify the application name on the app-image parameter otherwise the build will fail. A bit strange since build step 1 was run with --dest build/app- image. I have not yet tested the Debian package yet. --Github, my command-- In build step 1 I am running jpackage like so: Starting process 'command 'jpackage''. Working directory: /home/runner/work/settlers-installer/settlers-installer/app Command: jpackage --type app-image --dest build/app-image -i build/jpackage_input/app-0.1.0-SNAPSHOT/lib --main-jar app-0.1.0- SNAPSHOT.jar --main-class settlers.installer.App --name SettlersRemake --app-version 0.1.0-SNAPSHOT --description Settlers 3 remake - see https://github.com/ --vendor Hiran --icon build/resources/main/siedler3-helme-logo.png --resource-dir build/resources/jpackage Successfully started process 'command 'jpackage'' :app:jpackagePhase1 (Thread[Daemon worker,5,main]) completed. Took 12.919 secs. There is no error or any suspect message in stdout- Yet I investigated and found out that the app-image directory is almost empty. This is a problem for the second build step. And it is annoying that Gradle garbles the output with other stuff so I hope to have it separated correctly. :app:jpackagePhase2 (Thread[Daemon worker,5,main]) started. Bundler DEB Bundle failed because of java.lang.NullPointerException: Cannot invoke "java.lang.CharSequence.length()" because "this.text" is null > Task :app:jpackagePhase2 FAILED * What went wrong: Execution failed for task ':app:jpackagePhase2'. > Process 'command 'jpackage'' finished with non-zero exit value 1 Since gradle is not logging the command it invoked I will give you that line from the build file: commandLine 'jpackage', '--app-image', 'build/app- image/SettlersRemake', '--dest', 'build', '--resource-dir', 'build/resources/jpackage' --Github, your command-- Since you suggested to add --name on the second step, the first step runs as it was before. And again most files are missing in the output. Starting process 'command 'jpackage''. Working directory: /home/runner/work/settlers-installer/settlers-installer/app Command: jpackage --type app-image --dest build/app-image -i build/jpackage_input/app-0.1.0-SNAPSHOT/lib --main-jar app-0.1.0-SNAPSHOT.jar --main-class settlers.installer.App --name SettlersRemake --app-version 0.1.0-SNAPSHOT --description Settlers 3 remake - see https://github.com/ --vendor Hiran --icon build/resources/main/siedler3-helme-logo.png --resource-dir build/resources/jpackage Successfully started process 'command 'jpackage'' :app:jpackagePhase1 (Thread[Execution worker for ':',5,main]) completed. Took 12.672 secs. To verify what files had been created I ran a 'find' afterwards. I had expected the full application, and the JDK runtime. But I only see these files for the appimage: build/app-image build/app-image/SettlersRemake build/app-image/SettlersRemake/lib build/app-image/SettlersRemake/bin build/app-image/SettlersRemake/bin/SettlersRemake With that, the second step is called and outputs this much: Starting process 'command 'jpackage''. Working directory: /home/runner/work/settlers-installer/settlers-installer/app Command: jpackage --app-image build/app-image/SettlersRemake --name SettlersRemake --dest build --resource-dir build/resources/jpackage Successfully started process 'command 'jpackage'' Warning: app-image dir not generated by jpackage. :app:jpackagePhase2 (Thread[Daemon worker,5,main]) completed. Took 8.099 secs. I am surprised to see success, so my next step would be to evaluate the content of the .deb file. I doubt jpackage would have created all what was missing just now. However this evaluation will have to wait for a week. Hiran On Thu, 2022-04-07 at 14:16 -0400, Alexey Semenyuk wrote: > Hi Hiran, > > My apologies for not replying to your previous email.
