Installed the CE 2 SDK with Eclipse Kepler and Maven 3.1.1 On running the helloservice project I received the following error:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation

Sorry I just realized that you stated Maven 3.1.1. Please install an older version of Maven. According to the documentation, only Maven 3.0.4 is supported.

The issue is the 3.0.4 is no longer available from Apache. The oldest release is 3.0.5

It is available in the archives here: http://archive.apache.org/dist/maven/binaries/

With the latest version of maven, have you tried cleaning out the .m2 repository to see if that resolves the issues? Perhaps a library is corrupt. Also, were there new dependencies you added under pom.xml located under war?

If issue still persist please let us know.

I found the binary in Apache's archive: http://archive.apache.org/dist/maven/binaries/

You're going to want one of the following:
http://archive.apache.org/dist/maven/binaries/apache-maven-3.0.4-bin.zip
or
http://archive.apache.org/dist/maven/binaries/apache-maven-3.0.4-bin.tar.gz

The hope is to add support for the newer versions of Maven in the CE 2.0 service pack expected to be available in June.

Thanks for the help. Was finally successful.

Ended up reinstalling Eclipse, deleted the .m2 directory, reinstalled the SDK and used the collaboration plug-in, reimported the maven projects and compiled.
