how to build activemq source code

I downloaded activemq source code,tried to use maven to generate a eclipse
project. but I got 2 errors: [ERROR] Child module
E:\activemq-parent-5.8.0\activemq-amq-store\pom.xml of
E:\activemq-parent-5.8.0\pom.xml does not exist [ERROR] Child module
E:\activemq-parent-5.8.0\activemq-all\pom.xml of
E:\activemq-parent-5.8.0\pom.xml does not exist
for sure, the two files didn't contain pom.xml. I am not sure whether the
two files should be in activemq-amq-store and activemq-all
