      The theoretical maven remote repository priority is:

      However, when resolving a scope = import dependency, such as:

      The warehouse priority will become as shown in the figure below:

      Found that the central repository was reset to the default,  and all dependent downloads will become this repo priority in the future.

      When resolving scope = import dependencies, this place will cause the resolving repo to become the default central:

      Finally at this place, the default modelResoler repo will be replaced with the default central:
