I've tried to configure the example project in Idea and I found a couple of issues in parent pom.xml

[jtonic]

I came across an issue regarding 2 unresolved modules in main parent pom (they are in fact modules of a sub-parent module).
So, I did correct this locally.
Also I changed locally the version for spring and spring integration to 3.1.0.RELEASE and 2.1.0.RELEASE respectively and I fixed the groupId for commons-io.
