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:
{
"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"
}
]
}
Now suppose I have run the application for a while and want to upgrade that
package to version 1.5.0. How would I do that? 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." Am I doing something wrong, or is
this a bug?
BTW: the same thing happens if I copy a package into launcher/install and then
remove it to replace it with a new version.
Thank you!
Best regards,
Hans-Peter
