The result is that NoClassDefError's occur in instances where an external jar (i.e. importing a class from common-io) is referenced in test code and the same external jar is referenced in multiple NBM's.  Importing from external jars in qa-functional should be avoided.  See jira issue 6954 for more information.

+            <obfuscate>
+                <fileset dir="${build.classes.dir}"/>
+            </obfuscate>
+        </target>
+
+    For list of available properties check the imported 
+    nbproject/build-impl.xml file. 
+
+
+    Another way to customize the build is by overriding existing main targets.
+    The targets of interest are: 
+
+      -init-macrodef-javac:     defines macro for javac compilation
+      -init-macrodef-junit:     defines macro for junit execution
+      -init-macrodef-debug:     defines macro for class debugging
+      -init-macrodef-java:      defines macro for class execution
+      -do-jar:                  JAR building
+      run:                      execution of project 
+      -javadoc-build:           Javadoc generation
+      test-report:              JUnit report generation
+
+    An example of overriding the target for project execution could look like this:
+
+        <target name="run" depends="ZookeeperNodeMigration-impl.jar">
+            <exec dir="bin" executable="launcher.exe">
+                <arg file="${dist.jar}"/>
+            </exec>
+        </target>
+
+    Notice that the overridden target depends on the jar target and not only on 
+    the compile target as the regular run target does. Again, for a list of available 
+    properties which you can use, check the target you are overriding in the
+    nbproject/build-impl.xml file.

+========================
+BUILD OUTPUT DESCRIPTION
+========================
+
+When you build an Java application project that has a main class, the IDE
+automatically copies all of the JAR
+files on the projects classpath to your projects dist/lib folder. The IDE
+also adds each of the JAR files to the Class-Path element in the application
+JAR files manifest file (MANIFEST.MF).
+
+To run the project from the command line, go to the dist folder and
+type the following:
+
+java -jar "ZookeeperNodeMigration.jar" 
+
+To distribute this project, zip up the dist folder (including the lib folder)
+and distribute the ZIP file.
+
+Notes:
+
+* If two JAR files on the project classpath have the same name, only the first
+JAR file is copied to the lib folder.
+* Only JAR files are copied to the lib folder.
+If the classpath contains other types of files or folders, these files (folders)
+are not copied.
+* If a library on the projects classpath also has a Class-Path element
+specified in the manifest,the content of the Class-Path element has to be on
+the projects runtime path.
+* To set a main class in a standard Java project, right-click the project node
+in the Projects window and choose Properties. Then click Run and enter the

+To run the project from the command line, go to the folder that contains "ZookeeperNodeMigration.jar" and
+type the following:
+
+java -jar ZookeeperNodeMigration.jar
+
+To distribute this project, zip up the dist folder (including the lib folder)
+and distribute the ZIP file.
+
+Usage:
+ZookeeperNodeMigration input needs to be: 
+[Input Zookeeper IP Address or Hostname] [Input Zookeeper Port Number] [Output Zookeeper IP Address or Hostname] [Output Zookeeper Port Number]
+
+For example, if you execute the following command from command line line, the Zookeeper 
+nodes will get copied from Zookeeper server on localhost:9983 to Zookeeper server on localhost:19983 :
+
+java -jar ZookeeperNodeMigration.jar localhost 9983 localhost 19983
+
+
+If you do not have Java installed on the machine, you can use the packaged version of Java that is distributed along 
+with Autopsy. For example:
+
+"C:\Program Files\Autopsy-4.16.0\jre\bin\java.exe" -jar ZookeeperNodeMigration.jar localhost 9983 localhost 19983
