Added: src/plugins-build/deploy/src/java/org/apache/maven
MD5Sum.java
Log:
o making a general deploy plugin so that deploying any artifact can be
handled. right now there are separate deploy targets in each of the artifact
producing plugins which will not scale with the introduction of new
artifacts. adding a little md5 sum routine that we can use to make sure
that the file is intact upon the delivery and that it hasn't been
tampered with. we can get more sophisticated but using the md5 should
fix the problem of incomplete JARs being used in builds.
