Please tell us more about your question or problem

We use gradle Feature Variants and specify custom capabilities to make the mutually exclusive as shown here.
Renovate recognizes this as a dependency and tries lookup org.gradle.demo:producer-db-support as a maven artifact but does not find it for obvious reasons.
It outputs a warning saying "Failed to look up maven package org.gradle.demo:producer-db-support".

It seem the gradle managers matching is quite generous since it also tries to lookup any three comma separated string where the last string has a number in it.
I out case it tries to find team1:team2 as maven artifact for the following gradle code setOf("team1", "team2", "team3").

This brings us quite some headache. I'm not so fluent with typescript otherwise I'd try to create a PR.
So I kindly ask if someone could check if there is a good way to filter them out.
I think here would be a good point to start?
