bpel build broken due to xmlunit dependency in new bot plugin

Cannot build BPEL component due to new bot test plugin and its dependency on xmlunit. Simplest solution is to build an osgi plugin wrapper for xmlunit (as apodhrad has started) and to add that plugin to the tests/pom.xml; this is a stopgap to allow a quick Beta2 build to be achievable.

However, a longer-term solution (which would make Max happy - http://lists.jboss.org/pipermail/jbosstools-dev/2012-May/005253.html) might be to depend directly on the maven artifact, eg by adding this to bpel/tests/org.jboss.tools.bpel.ui.bot.test/pom.xml:

+       <dependencies>
+               <dependency>
+                       <groupId>xmlunit</groupId>
+                       <artifactId>xmlunit</artifactId>
+                       <version>1.3</version>
+                       <scope>test</scope>
+               </dependency>
+       </dependencies>

or else to provide this org.custommonkey.xmlunit plugin via a target platform [1] or on the JBT composite requirements site [2].
