maven versions release candidates and snapshot

My goal is to release a project which have a single dependency. I have a nexus repository where i deploy both snapshot and release versions.

The one dependency I have has

group:artifact:1.1.0-SNAPSHOT

and the following Release Candidate is released in my nexus repo

group:artifact:1.1.0-RC1

when asking to the versions plugin to resolve the dependencies, it claims that no new dependency is available. So he consider that

1.1.0-SNAPSHOT > 1.1.0-RC1

However, If in my project, i have version 1.0.0-SNAPSHOT, version 1.1.0-RC1 is resolved as the newest version.

What am I missing? (I looked into the plugin sources and we have the following snippet:

String otherQualifier = otherVersion.getQualifier();

if ( otherQualifier != null )
{
  if ( ( qualifier.length() > otherQualifier.length() )
      && qualifier.startsWith( otherQualifier ) )
  {
    // here, the longer one that otherwise match is considered older
    result = -1;
  }
  else if ( ( qualifier.length() < otherQualifier.length() )
      && otherQualifier.startsWith( qualifier ) )
  {
    // here, the longer one that otherwise match is considered older
    result = 1;
  }
  else
  {
    result = qualifier.compareTo( otherQualifier );
  }
}

which seems buggy to me. Any idea?

As of https://docs.oracle.com/middleware/1212/core/MAVEN/maven_version.htm

All versions with a qualifier are older than the same version without a qualifier (release version).

For example:

1.2-beta-2 is older than 1.2.

Identical versions with different qualifier fields are compared by using basic string comparison.

For example:

1.2-beta-2 is newer than 1.2-alpha-6.

and

Maven treats the SNAPSHOT qualifier differently from all others. If a version number is followed by -SNAPSHOT, then Maven considers it the "as-yet-unreleased" version of the associated MajorVersion, MinorVersion, or IncrementalVersion.
