I went ahead and ran
jar cvf aspose-cloud.jar * when in the bin directory. That produces the jar for the client SDK. There’s still a problem with the sources not compiling.
This issue has been logged into our issue tracking system as MARKETING-6442. We will upload SDK JAR file as soon as possible and will always keep a copy of latest JAR file in the repository.
You will be notified as soon as it is done.
