NWDS 7.5 - missing JAR files for adapter module

Dear experts,

I am following this blog

https://blogs.sap.com/2017/07/05/api-token-via-http-lookup-in-adapter-module/

and I downloaded the source code from GitHub and set up an EJB project in my NWDS.
But now NWDS is complaining that it is missing a few JAR files:

Where can I get

com.sap.aii.adapter.xi.ms*.jar
and
com.sap.aii.af.sdk.xi.mo.xmb*.jar

from? I looked on our PO system but could not find the files. Does anyone have an idea
where to get these from?

Thank you, Peter
