   <name>Git Commit Id Plugin Maven Mojo</name>
+  <description>
+    git-commit-id-plugin is a plugin quite similar to
+    https://fisheye.codehaus.org/browse/mojo/tags/buildnumber-maven-plugin-1.0-beta-4 for example but as buildnumber
+    only supports svn (which is very sad) and cvs (which is even more sad).
+    This plugin makes basic repository information available through maven resources. This can be used to display
+    "what version is this?" or "who has deployed this and when, from which branch?" information at runtime - making
+    it easy to find things like "oh, that isn't deployed yet, I'll test it tomorrow" and making both testers and
+    developers life easier.
+
+    The data currently exported is like this (that's the end effect from the GitRepositoryState Bean):
+    {
+    "branch" : "testing-maven-git-plugin",
+    "commitTime" : "06.01.1970 @ 16:16:26 CET",
+    "commitId" : "787e39f61f99110e74deed68ab9093088d64b969",
+    "commitUserName" : "Konrad Malawski",
+    "commitUserEmail" : "konrad.malawski@java.pl",
+    "commitMessageFull" : "releasing my fun plugin :-) + fixed some typos + cleaned up directory structure + added
+    license etc",
+    "commitMessageShort" : "releasing my fun plugin :-)",
+    "buildTime" : "06.01.1970 @ 16:17:53 CET",
+    "buildUserName" : "Konrad Malawski",
+    "buildUserEmail" : "konrad.malawski@java.pl"
+    }
+
+    Note that the data is exported via maven resource filtering and is really easy to use with spring -
+    which I've explained in detail in this readme https://github.com/ktoso/maven-git-commit-id-plugin
