m2e plugin problem. project does not build

I am pretty new to Maven, I have installed the eclipse to maven plugin from here.

even though through the command line the project compiles and builds the desired war, when i import the project to my eclipse i have lots of errors and it does not recognize开发者_Go百科 all the dependencies.

I have tried to: run mvn eclipse:eclipse, purge the dependencies, importing it not through maven, setting the MAVEN2_CLASSPATH_CONTAINER to the .m2 folder.

but nothing works, Any ideas??

Can you follow steps mentioned here?

mvn package command doesn't run successfully after mvn clean command if done from command prompt
