Intellij Idea Maven "kann nicht verbinden" Fehler

Vielleicht können Sie mir helfen
Ich habe eine seltsame apache maven problem, beim öffnen von meinem Projekt in Intellij Idea 13.
Wenn Projekte geöffnet war, habe ich keine Bibliotheken Externe Bibliotheken Abschnitt. Und an alle pom.xml Dateien vom diff Module ich sehe den Fehler "kann Nicht verbinden".

Habe ich versucht zu Entkräften Cache/Neustart-Idee, versuchen Sie es mit Maven Reimport-problem, sondern immer noch einen Platz.
Aber wenn ich mvn clean installieren und bereitstellen von meinem Vorhaben, alles funktioniert einwandfrei.
Ich benutze Maven 3.2.3. und Java 1.8.
