Errors in pom.xml with dependencies (Missing artifact...)

Question

A friend has passed me a Maven project that I'm trying to run locally in my computer. All that I have done in Eclipse, I selected:

File -> Import -> Existing Maven Projects

After that, the project showed me 4 errors in my pom.xml (Missing artifact..):

I tried removing the content of .m2 folder and then in Eclipse I clicked on my project and chose "Run as" -> "Maven clean" and then "Run as" -> "Maven install". But I still have the same errors. I'm new with Spring so I dont know what else to do.

EDIT:

When I try to do: run as/ maven install, this is what my console says:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".

EDIT2: This is my complete pom.xml: https://dl.dropboxusercontent.com/u/31349296/pom.xml It looks pretty awful when I try to paste the code here.

Answer 1

It seemed that a lot of dependencies were incorrect.

Download the whole POM here

A good place to look for the correct dependencies is the Maven Repository website.
