@fvarrui Please look into the issue.

Hi @SaptarshiSarkar12!

I fear you can fix it ... unless you code a patch for JavaPackager and make a PR.

I'll take a look into it ASAP.

Anyway, it's showing a warning message, not an error. Have you tried to run the generated AppImage?

@fvarrui Yes, the AppImage runs pretty well.

Thank you for giving your valuable time to resolve the issue!

@fvarrui Please check this docs of freedesktop about metadata file.
It says to create a app_name.metadata.xml file in /usr/share/metainfo/ directory before building the AppImage. I think this file can be auto-created by JavaPackager before initiating the building of AppImages. So, it might be a good feature we should bring in this project.
@fvarrui Let me know your opinion.

@SaptarshiSarkar12 Ok, I've just check this example and it seems that all required data is available in JP. As it's related to issue-345, and there's already a branch for this issue, changes will be made in this branch.

As far as I understand, this is not only for AppImage, but DEB and RPM too, right?

Ok @fvarrui, that's great!
No, there is some problems regarding DEB and might be RPM also. The problem is that the description shown by Software Install application in ubuntu (when trying to install DEB package) is not as what is provided to JavaPackager. Below are the required relevant screenshots and links :

So, do you mean that metadata file has also to be provided by DEB and RPM packages?

Yeah @fvarrui, it might help. Also, the application icon is not present when opening DEB (might be the same case with RPM) through Software Install application in Ubuntu 23.04.
