Invalid 2.0-m4 build in maven2 repository

After switching to "m4" in pom.xml I got strange errors. I have downloaded the new version from sourceforge, and now there no any errors.

Here is a stack trace:

you are probably using too little modules of spring (spring-context without spring-beans). Use either spring.jar or spring-beans.jar w/ spring-context and spring-core.

Thanks for a reply,

but, definitely this is not a case.
I am using spring* for a long time. I have been working with EA version and now I am using RC1.
