Is it a problem with the authentication on the repository? Apologies, but my understanding of Maven is very limited. My .m2/settings.xml file is empty, and I do not know what to put in it.

I am not a programmer: I just need to get the WAR and deploy it on Tomcat.

Can someone help me with some spoonfeeding?

Thanks!

Welcome to CodeRanch!

Simply put, none of your configured repositories contain the 7.0-beta4 version of the various DSpace modules that you require.

How do you figure there's a 7.0-beta4 version at all? Can't you use version 7.0-beta3 or even better, version 6.3?

[Diego Schiavon]

Are you basely insinuating that I might have wasted precious hours of my life trying to compile the wrong version?

Well, it seems you are right. I downloaded 6.3 and only had to adjust the Java version. And now:

Clearly you're not a programmer! Wasting precious hours wrestling with some picky technical detail is like a way of life for programmers.
