Can not compile custom parser in Metron

[#1]

I use Metron 0.4.1 and I want to compile the example of custom parsers witch it was written in metron site.

I built a directory in /home/metron/metron-platform with mkdir -p extera_parsers/src/{main,test}/java and followed the link that I mentioned above.

When I used mvn clean package, I see this error: "POM for org.apache.metron:metron-parsers:jar:0.4.1 is missing :jar:0.4.1 is missing, no dependency information available"

How can I solve it?

thanks.
