I can be a bit more precise on the error: it appears I am missing a dependency:

PatentPublicData patrick$ java -cp BulkDownloader/target/BulkDownloader-0.0.1-SNAPSHOT.jar gov.uspto.bulkdata.cli2.BulkData -cp BulkDownloader/target/dependency-jars/

The error you received "NoClassDefFoundError" states that java can not find the class file, might be other classes it can not find but java will complain on the first class it can not initiate. The usual cause is the jar holding the class file is not in your classpath. This particular class is located within jar file dependency-jars/jopt-simple . Check that the jar file exists. If it does your classpath is not setup correctly. Since I chose not to package the third party jars into the main jar, the classpath must include the third party dependency jars on the classpath as well as the application jar.

Classspath should contain both:
target*
target\dependency-jars*

Windows classpath, note semicolon as separator:
BulkDownloader\target*;BulkDownloader\target\dependency-jars*

Linux classpath, colon as separator:
BulkDownloader/target/:BulkDownloader/target/dependency-jars/

Correct Classpath in Use:
java -cp BulkDownloader/target/:BulkDownloader/target/dependency-jars/ gov.uspto.bulkdata.cli2.BulkData --type application --years="2016" --limit=1 --outdir="download"

Example scripts can be located here.

Also as a suggestion, might be easiest to package as a zip file using"mvn clean package", the generated zip file PatentPublicData/target/PatentPublicData-0.0.1.SNAPSHOT.zip will contain the typical directory structure and setup for an application.

Hope this helps, if you are still having issues feel free to contact me again.

Brian,

Thank you for the rapid response!

OK, I got it working. I knew I was in classpath hell, the very reason I use Java infrequently enough to never remember how to resolve it. I didn't realize I needed both directories in the CP.

For my Mac I had to do a couple of minor changes to your download.sh script (lib->target; Project path was up two, down one; the parameters were for .cli not .cli2), but those were easy to investigate. If it is useful, I can send the resulting file.

But the core insight was how to get the two directories in the CP.

Thanks again. (You can resolve this.)
