WSO2 samples Maven pom.xml - maven

Question

I would like to package my project for wso2 into Maven, and first step is to place WSO2 samples into a maven build and then build upon that...however, not able to create pom.xml that will compile the sample code so far.
After following some trails online: WSO2 BAM 2.0 libraries in Maven
Which included downloading and installing a pom into local repository because it did not exist on wso2 repository, still getting errors...
Thanks for any assistance or best yet, if someone has a pom.xml for WSO2 samples and can share it...
Here is the current pom:

Answer 1

Can you build this pom file just like this,
mvn clean install -c
This will ignore the checkssum error.

Answer 2

Replace your repositories tag with the following. Your dependency will be available in one of these repositories. And if the checksum error seems to persists, please refer to #Harsha's answer.
