Try downloading the file manually from the project website.

Then, install it using the command:
mvn install:install-file -DgroupId=org.jboss.snowdrop -DartifactId=snowdrop-vfs -Dversion=1.0.1.GA -Dpackaging=jar -Dfile=/path/to/file

Alternatively, if you host your own repository you can deploy the file there:
mvn deploy:deploy-file -DgroupId=org.jboss.snowdrop -DartifactId=snowdrop-vfs -Dversion=1.0.1.GA -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]

2) org.jboss.snowdrop:snowdrop-deployers:jar:1.0.0.GA
3) org.jboss.snowdrop:snowdrop-vfs:jar:1.0.1.GA
