Maven build failed for struts2 showcase

Hi I am new to Struts2 and Maven. I read about the struts2-showcase and found the maven repository at http://maven-repository.com

maven repository I am using is http://maven-repository.com/artifact/org.apache.struts/struts2-showcase/2.3.16.3

I am trying to create one project using the given pom.xml given in the maven repo. But whenever I run mvn install, its giving build failure. Firstly I was doing this by creating one project using

mvn archetype:generate -DgroupId=struts -DartifactId=struts2-showcase -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false
​

command in console. Then I opened the pom.xml and added the dependency.

<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-showcase</artifactId>
<version>2.3.16.3</version>
</dependency>


But when I run the command

mvn install
​

I got error in test and at last Build failure.

But Later I deleted all and created a directory manually and inside that I created one pom.xml and pasted all the contents got from http://maven-repository.com/artifact/org.apache.struts/struts2-showcase/2.3.16.3/pom

Then all worked perfectly but nothing to compile and nothing to test and got build successful. But when I deployed it got the error and build failed.

I know I am doing something terribly wrong. Someone please show me the way to make it work. As application server I used JBoss (wildfly).
