Offline Mode Design

* UPDATE: 18-April-2005

  We cannot take the approach outlined below of detecting which remote
  repositories are "really" offline, since offline mode is more of a behavior,

                getLogger()
                        .debug("Skipping update check for " + artifact + " (" + file + ") from " + repository.getId()
                                + " (" + repository.getUrl() + ")");
            }

            return false;
        }

        if (getLogger().isDebugEnabled()) {
            getLogger()
                    .debug("Determining update check for " + artifact + " (" + file + ") from " + repository.getId()

        RepositorySystemSession session = legacySupport.getRepositorySession();

        if (session != null) {
            request.setOffline(session.isOffline());
            request.setForceUpdate(RepositoryPolicy.UPDATE_POLICY_ALWAYS.equals(session.getUpdatePolicy()));
        }
    }

    public ResolutionGroup retrieve(

    @Disabled

        ArtifactRepositoryPolicy policy = new ArtifactRepositoryPolicy(
                true, ArtifactRepositoryPolicy.UPDATE_POLICY_ALWAYS, ArtifactRepositoryPolicy.CHECKSUM_POLICY_FAIL);

        ArtifactRepository repo = artifactRepositoryFactory.createArtifactRepository(

        return result;

        if (p1 == p2) {

        // update policy doesn't affect contents
        return p1.isEnabled() == p2.isEnabled() && Objects.equals(p1.getChecksumPolicy(), p2.getChecksumPolicy());
