Here is my clean install -x result:
[INFO] Scanning for projects...

[INFO] --
Does the class org.apache.maven.shared.filtering.MavenFilteringException
exist in file:/C:/Users/utopcu/.m2/repository/org/apache/maven/shared/maven-filtering/1.0-beta-2/maven-filtering-1.0-beta-2.jar
?
The error message suggests that it doesn't. Maybe the JAR was corrupted somehow.
I'm also wondering where the version 1.0-beta-2
comes from; I have 1.0
on my disk. Try version 2.3
of the WAR plugin.
