Hello, it's me again.

I ran into the following problem:

When the eclipse installer tries to install my self created setup task extension (in this post I'll only mention the 'cli-task' but there are others with the exact same problem) the installer throws

Internal Error
Cannot complete the install because one or more required items could not be found

org.eclipse.core.runtime.CoreException: Cannot complete the install because one or more required items could not be found.

Contains: Missing requirement: artificial_root 1.0.0.v1465924705675 requires 'task-cli.feature.group 0.0.0' but it could not be found

I included the Setup file and the setup task extension can be found here : https://github.com/maybeec/oomph-task-cli. I actually have no idea where the problem is since Eclipse itself can install the extension without problems

Steffen,

Looking at your model I see

<eAnnotations source="http://www.eclipse.org/oomph/setup/Enablement">
<details key="variableName" value="p2.cli"/>
<details key="repository"
value="http://maybeec.github.io/oomph-task-cli/update"/>
<details key="installableUnits" value="task-cli.feature.group"/>
</eAnnotations>

Using the Repository Explorer to look at this site, I see it doesn't
have a feature with that ID. Instead it has

com.github.maybeec.oomph.task.cli.feature.feature.group

So just be sure you've specified the right ID for the update sites.
