You will have to check your classpath configuration. Mere importing your source tree into eclipse does not work ( eclipse is shitty when it comes to understand maven files ). You should try to recreate classpath / project with maven.
If you are running from Eclipse like Run configuration check on the botton view (Maven build in tree) what maven do you use in your build: it can be embedded or external. If there are embedded change it to external, if you are already add it to eclipse.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
