Need help setting jLinkOptions for jpackage plugin

[david-hall]

Hi Petr,

I have a working gradle 7.5.1 build.gradle for my project. It includes the jpackage plugin:

plugins { id "application" id "org.panteleyev.jpackageplugin" version "1.5.1" }

It has no linux configuration block, but does have one for mac and windows. It currently builds successfully on windows, mac and linux.
The entire build.gradle file can be seen at https://github.com/david-hall/vzome/blob/linux-distro/desktop/build.gradle

I can't figure out how to pass any jLinkOptions to the linux build as shown at https://github.com/petr-panteleyev/jpackage-gradle-plugin.

I tried adding the following linux configuration block and then building on linux:
linux { jLinkOptions = listOf( "--compress=0", "--no-man-pages" ) }
The build failed, saying Could not find method listOf() for arguments [--compress=0, --no-man-pages] on task ':desktop:jpackage' of type org.panteleyev.jpackage.JPackageTask.. The complete error log for the build can be seen at https://github.com/vorth/vzome/actions/runs/4179418828/jobs/7239343093

Just as a guess, I tried replacing listOf() with just plain square brackets like this:
linux { jLinkOptions = [ "--compress=0", "--no-man-pages" ] }
Again the build failed. This time saying Could not set unknown property 'jLinkOptions' for task ':desktop:jpackage' of type org.panteleyev.jpackage.JPackageTask. This error log can be seen at https://github.com/david-hall/vzome/actions/runs/4180743157/jobs/7242018140

Any idea what I'm doing wrong?

Thanks,
David

On a side note, I noticed a couple of typos in the README.md on your github home page. The Default Command-Line Arguments section says Each argument should be specified using <argument> configuration parameter.. I think that argument should be arguments (plural) in that sentence.

Also, the Example in that same section misspells arguments as argumens (missing a t).

Just for a bit of context, I'm not sure if I even need to set the compression level for jpackage. I can't find anything saying what its default value is. I assume it's 0, but I want to specifically set it to 0 and see if that fixes a linux distro problem I've recently encountered.

I had been building my linux distros with Java 17.0.4.1 with no problem. I had no problem installing successive versions of the app on my Debian 11 computer. Recently, my build server was upgraded to Java 17.0.5+8 and every build since then builds successfully, but when I try to install it on my Debian 11 computer, it fails saying MyApp.deb uses unknown compression for 'control.tar.zst'. giving up. I'm hoping that specifically setting the compression to 0 will avoid this issue, but I'm really grasping at straws. The problem definitely started when the Java version was bumped up. I don't have any other ideas as to how I can revert to the prior packaging format without also rolling back the Java version.

I'm open to any ideas with regard to this original issue, but in any case, I'd like to get jLinkOptions working in my build.gradle.

Thanks

Hi,

For some reason setJLinkOptions tranlates into JLinkOptions with capital J. No idea why cause I don't know Groovy and always use Kotlin DSL in gradle.

JLinkOptions = [ "--compress=0", "--no-man-pages" ]

Thanks Petr,

Changing the first letter of JLinkOptions to upper case solved part of the issue for me. At least I was able to use it with the exact syntax you mention above rather than the listOf(...) syntax shown on your README page. By using the upper cased syntax with square brackets, Gradle was able to parse and execute the build in linux, and that was my main question for you regarding the plugin.

I would suggest that it might be helpful to modify the examples in README so they accurately represent a syntax that works in Gradle as well. Also, you have one related typo on the README page. It says argumens instead of arguments. The example withthe typo also uses the listOf(...) syntax. I wonder if it should be changed to the square bracket form as well.

Although I was able to get the compress=0 JLinkOptions set so I could build with no errors, I still have the same issue with the Debian 11 installation reporting the error MyApp.deb uses unknown compression for 'control.tar.zst'. giving up. At this point, I'm pretty confident that it's not an issue with the jPackage compression, but rather, somewhere else in the build pipeline. I'll continute to chase that issue, but thanks for your help with the plugin syntax.

With regards to compression question I can only suggest generating app image which I always do for myself. It does not fit into packaging infrastructure but it works all the time. Generating Linux packages like deb or rpm is highly dependent on a particular distro flavor and may not work at all.
