NoClassDefFoundError when running Tests or Tomcat targets

[hoserdude]

Ran the tomcat7 target and it crashed with the following stack. Tried running a mvn clean install and the tests failed with the same NoClassDefFoundError. I thought that I may have a bad mix of Spring components in my repo so I blew it away and started fresh, same deal.

I figured it out - added spring-core and spring-beans to the pom and that seemed to get things up and running. I've updated my fork with this change. hoserdude@c5bbd91

Hi,
thanks for your feedback.
spring-beans and spring-core are transitive dependencies so they shouldn't be needed.
However, you're not the first one who mentions about this issue ( @cyrille-leclerc had this issue as well).
It seems like a Maven issue. Which version of Maven and which OS are you using?

Thanks,
Michael.

Hi @michaelisvy, I created Pull Request #29. I had to support a CloudBees customer this week who had the same problem.

PR #29 may be a bit verbose but it is standard Maven and it has fixed the ClassNotFoundException in all the support cases I faced at CloudBees.

I will update to 3.10, undo my changes and see if that works.

Good news, that seemed to work without a hitch. Upgraded to 3.1.0, Maven re-downloaded the internet and the build/test went through.
