By default, CVSNT will corrupt jars during `mvn deploy`. Vanilla CVS less likely, but still possible due to Keyword substitution. ScmWagon needs to perform checkout and add commands with the '-kb' flag (binary).
UPD: In some configurations svn will automatically add the svn:eol-style property to newly added text files. ScmWagon needs to perform the add command without adding automatic properties.
UPD2: Msysgit will checkout wagon-scm test-resource with CRLF by default, breaking the test. Need to clone with core.autocrlf=false
