> Hi!
> I'm currently exploring how to use the Sling feature launcher in practice, and stumble over the following problem. It is nicely possible to install content and application packages by using a feature like e.g. this:
> {code:json}
> {
>   "id": "com.composum.platform:composum-startup-featurelauncher:slingosgifeature:somewildtry:1.0.0-SNAPSHOT",
>   "title": "install a package",
>   "content-packages:ARTIFACTS|required": [
>     {
>       "id": "com.composum.platform:composum-platform-commons-package:zip:1.4.0"
>     }
>   ]
> }
> {code}
> Now suppose I have run the application for a while and want to upgrade that package to version 1.5.0. If I just change the version number of the package (and the feature id), I actually see both versions of the package installed in the package manager. When I look into the logfile, there was actually an attempt to deinstall the package, but that fails due to "Unable to uninstall package. No snapshot present." (full stacktrace below).
> BTW: the same thing happens if I copy a package into launcher/install and then remove it to replace it with a new version.
> I'm not quite sure what should happen here, but I think the old package should be gone when given in a feature. That could mean creating a snapshot when installing the package (which likely has doubtful value), or just deleting the old package.
