Klasse nicht gefunden Exception - Maven Eclipse

Question

Ich habe mit Maven ein dynamisches Webprojekt erstellt. Ich habe diesen (https://github.com/Codearte/jfairy) gefälschten Daten Generator Plugin als Maven in meinem pom.xml wie wie unten verwendet:

<dependency> 
    <groupId>io.codearte.jfairy</groupId> 
    <artifactId>jfairy</artifactId> 
    <version>0.5.3</version> 
</dependency> 

Aber ich habe den Fehler wie wie folgt:

java.lang.NoClassDefFoundError: io/codearte/jfairy/Fairy

Eclipse Maven Integration funktioniert nicht gut. Sie können gehen Verzeichnis zu projizieren und diesen Befehl ausführen:

mvn eclipse:clean 
mvn eclipse:eclipse 
mvn install 

Mit anderen Worten, jedesmal wenn Sie pom.xml Sie besser

mvn eclipse:eclipse 

in Shell verwenden, ändern.
