I have downloaded and added the commons.imaging jar files to my project
library folder in Netbeans.  I copied the source code from github for
src/test/java/org/apache/commons/imaging/examples/MetadataExample.java

when I run the program I get an error message at the first code line:
final ImageMetadata metadata = Imaging.getMetadata(file);

The error is Exception in thread "AWT-EventQueue-0"
java.lang.NoClassDefFoundError: org/apache/commons/io/build/AbstractOrigin

I am an experienced java programmer but I have no experience with the
commons.imaging library.  Any suggestions to help me resolve this issue is
greatly appreciated.

I have attached a screenshot of the code & error message.
