dom4j maven missing artifact

I'm having a problem with dom4j in pom.xml.

<dependency>
    <groupId>org.dom4j</groupId>
    <artifactId>dom4j-1.4</artifactId>
    <version>1.4</version>
    <type>jar</type>
    <scope>compile</scope>
</dependency>

is annotated with "Missing artifact org.dom4j:dom4j-1.4:jar:1.4". Here's the pom:

When I replace the dom4j dependency with

<dependency>
    <groupId>dom4j</groupId>
    <artifactId>dom4j</artifactId>
    <version>1.6.1</version>
</dependency>

I'm getting the same error, but in the first line

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

Can you help?

First remove your existing jar file from your .m2 folder, again run the maven install. Then your problem will solve.
