Define SCP destination for S4HANA BAPI call with Cloud SDK
I am looking for a way to call S4HANA on-premise BAPI locally and on SAP Cloud Platform with Cloud SDK. The problem is how to define RFC destinations just like HTTP ones.
I also encountered JCo class not found exception and could not find a suitable workaround.
Locally
In HTTP destination, I can provide environment variables like the following:
set destinations=[{name: "destName", url: "URL", username: "username", password: "password"}]
But it is not clear how to define RFC destination, which properties are mandatory like jco properties.
SCP Cloud Foundry
I created a RFC destination on SAP Cloud Platform.
But I could not find a way to decorate this destination to involve additional properties in Cloud SDK just like HTTP destination.
Destination destination = DestinationAccessor.getDestination(destName);
destination.asHttp().decorate(DefaultErpHttpDestination::new);
Please note that when I do bapi call, the RfcDestination is not acceptable only type Destination is required. RfcDestination is not an implementation class of interface Destination.
JCO Class Not found exception
java.lang.NoClassDefFoundError: com/sap/conn/jco/JCo
There is a known issue when using SAP Java Build Pack with Spring boot. I added the jar file sapjco3.jar manually to project classpath. But it still did not work.

Update
JCO Class Not Found exception at run time
- You are right. I deployed app on SCP and then call rest APIs I provided to invoke BAPI of S4HANA On-premise system. Then I got this exception at run time.
- I am using a Spring Boot application.
- The Spring boot project is generated by SAP Cloud SDK spring archetype.
- Please see error stack trace below.
- Right click my project -> build path -> Configure build path -> Choose libraries tab -> add external jars
- I deployed my app as Jar file.

One thing I want to highlight is an official documentation provided by SAP says "It is not possible to use the SAP Java Connector with Spring Boot applications".
SAP Java Connector with non spring boot application
I created a new project based on SAP Cloud SDK archetypes scp-cf-tomee and tried to call bapi. JCo issue is gone I think but I got a new excetion "User Information is not set" when invoking Bapi. Someone has the similar issue but seems no solution yet.

Decorate destination
I agree with what you explained. Maybe it is not required to do it as Http destination. But I was stuck due to SAP Java Connector issue.
Local RFC Destination definition
Actually I did not know what properties are required for RFC destination. If I just use the HTTP one, I would get http status 404 and service not found exception.
Solution
Update: Check out the latest SAP Cloud SDK documentation on BAPI calls.
Thanks for the update. Answering based on your updated information inside the original question. Again going over each individual headline.
JCO Class Not Found exception at run time
The usage of the Java Connector is only usable when using the "traditional deployment" of Spring which involves building and deploying a war file instead of a jar file.
SAP Java Connector with non spring boot application
The usage of the Java Connector requires to have a protected backend and an app router. I assume you do not use that, that is indicated by the error message User Information is not set.

Local RFC Destination definition
As per my knowledge using the Java Connector from a local deployment is not foreseen. You have to deploy your app to the SAP Cloud Platform for this purpose.
Concerning the question which properties to set on the RFC destination, you can refer to the Javadoc of the Java class DestinationDataProvider which you can extract from the JCo archive after downloading it from https://support.sap.com/jco
