---------------------------------
    Issue Type: Task  (was: Bug)

> Make IT tests use "outer" Mimir caching as well
> -----------------------------------------------
>
>                 Key: MNG-8646
>                 URL: https://issues.apache.org/jira/browse/MNG-8646
>             Project: Maven
>          Issue Type: Task
>          Components: Core
>            Reporter: Tamas Cservenak
>            Assignee: Tamas Cservenak
>            Priority: Major
>             Fix For: 4.0.0-rc-4
>
>
> As it turned out, ITs were not using Mimir as they redefined Maven Central to 
> allow snapshots, and that made Mimir not handle the IT used Maven Central 
> (while those did not contain snapshots, it was still pointing at canonical 
> Maven Central URL).
> Fixing this revealed several other (related or unrelated) issues:
>  * MavenProject was NPE prone regarding remote repositories handling
>  * MappedList was NPE prone regarding null values (emitted by MavenProject 
> remote repositories)
>  * several ProjectModelBuilder (detailed below) had no remote repositories 
> set anymore (as central is not in super POM anymore)
>  * some ITs revaled ReactorReader issues as well
> org.apache.maven.project.DefaultProjectBuilder issues:
>  * model request type CONSUMER_PARENT is used for non-locally built projects 
> (ie. plugins invoked with direct mojo invocation), this seems strange. This 
> skips CI friendly replacement for example as shows in Maven ITs
>  * remote repositories are injected ONLY when injecting lifecycle plugins 
> (processPlugins=true). This was ok when root pom was defining default 
> repository, but that's not the case anymore, and this results in projects 
> built that has 0 remote reposes.
> At the end of the day, all issues were fixed but one IT that we declared 
> "invalid" was disabled (w/ remark about why's).
