Answer 1

You need to do this in order to include the Apache Commons CLI library in your classpath:

java -cp '.:/path/to/cli.jar' -jar jodconverter-cli-2.2.2.jar x.doc y.pdf

If you're on Windows, use a semicolon ; instead of the colon : in specifying the classpaths.

Answer 2

Because you don't have the dependencies specified in the classpath (The first one being exactly what the error is telling you, the apache.commons.cli library).

You either need to specify them on the command line or in the manifest in that jar.
