I think you may need to install https://github.com/wbuchanan/StataJavaUtilities first. One of the difficulties with Java is managing dependencies and compiling these packages with the one at the link above started to cause more issues across more packages when I was still making updates to the classes I created to make interacting with the API a bit easier.
