maven/0002-Use-custom-resolver.patch

Subject: [PATCH 2/5] Use custom resolver

WorkspaceReader is used to resolve main dependencies, but we had to
add this resolve to ProjectModelResolver and DefaultModelResolver as
well because these are instantiated early and used to build model of
project when WorkspaceReader is not available yet.
