No plugin found for prefix 'pitest-git'

https://github.com/assertj/assertj/runs/7763829056?check_suite_focus=true shows an error while trying to find the

[ERROR] No plugin found for prefix 'pitest-git' in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo] available from the repositories [local (/home/runner/.m2/repository), central (https://repo.maven.apache.org/maven2)] -> [Help 1]

I'm not sure what this error exactly means, assertj-core uses this profile (showing here the effective pom view):

I was able to find the plugin in maven central: https://repo.maven.apache.org/maven2/com/groupcdg/pitest-git-maven-plugin/0.2.0/ Not sure what the role of the metadata is but it looks ok as there is a pitest-git prefix there: https://repo.maven.apache.org/maven2/com/groupcdg/maven-metadata.xml

<plugin>
  <name>pitest-git-maven</name>
  <prefix>pitest-git</prefix>
  <artifactId>pitest-git-maven-plugin</artifactId>
</plugin>

I wonder if it's something related to the plugin repositories :thinking:

Is there something we can look at?

Note:

AssertJ has moved to a multilmodule project recently and maybe that had an impact.
Idea complains it can't find the pitest-git-maven-plugin
