java.lang.NoClassDefFoundError: org/apache/http/conn/ClientConnectionManager

Hello,

Unfortunately I have a small amount of knowledge about Maven and Java and am trying to run the Create your first with project with the Engine APIs and Maven and am running into a problem. I am trying to run the rest api example and am getting the following errors. Ive added some of the relevant POM file entries. What am I doing wrong?

Thanks
