Maven pom.xml Fehler

Question

bekomme ich folgende Fehler den mvn -X validate Befehl:

The POM for org.apache.maven.plugins:maven-jar-plugin:jar:2.3.1 is invalid, transitive dependencies (if any) will not be available: 3 problems were encountered while building the effective model for org.apache.maven.plugins:maven-jar-plugin:2.3.1 
[ERROR] Invalid packaging for parent POM org.apache.maven.plugins:maven-jar-plugin:2.3.1, must be "pom" but is "maven-plugin" @ 
[ERROR] Invalid packaging for parent POM org.apache.maven.plugins:maven-jar-plugin:2.3.1, must be "pom" but is "maven-plugin" @ 
[FATAL] The parents form a cycle: org.apache.maven.plugins:maven-jar-plugin:2.3.1 -> org.apache.maven.plugins:maven-jar-plugin:2.3.1 @ 

Meine Umgebung ist folgende:

mvn --version

Ich habe nach einer Antwort gesucht, bis jetzt, kein Glück. Danke im Voraus.
