Support for custom WXS entries during MSI packaging

[dmvanderuit]

Hi,

I've got a question regarding the packaging of the application. In the section on native distributions, the docs mention that the packaging uses JPackage under the hood. In JPackage, it's possible to further customise the installer using WXS files. Is this something that is supported in the packaging of MSI packages run by the Gradle task in Compose too?

Thanks in advance.

I think this might already be possible. In AbstractJPackageTask.kt we already have

if (targetFormat != TargetFormat.AppImage) {
    …
    cliArg("--resource-dir", jpackageResources)
    …
}

where jpackageResources is defined here:

@get:LocalState
protected val jpackageResources: Provider<Directory> = project.layout.buildDirectory.dir("compose/tmp/resources")

so apparently compose/tmp/resources is passed to jpackage via --resource-dir and files to modify the input for Wix creating the msi such as a modified main.wxs could be copied there.

ah, well, OK, but then there's also cleanDirs(jpackageResources) executed during prepareWorkingDir, so essentially anything we copy to compose/tmp/resources to modify the input data for Wix will be deleted before running jpackage.

Any updated on this? It can be very useful! I have a need to write a registry entry during installation to register custom URI schema for my App
