Pulling the latest version of both the source code and the jar file in the releases (https://github.com/fortify/ssc-restapi-client/releases/tag/v22.1) results in an error when attemting to run the application in a stand alone Jar format.
Previous versions of the JAR file allowed for the following command to be run without issue
java -jar ssc-restapi-client.jar.
Running the above command with the latest JAR version results in the error:
no main manifest attribute, in ssc-restapi-client.jar
This issue occurs on regardless of platform or java version used.
