Generate OData VDM using S/4 HANA SDK leads to errors

问题

I tried to generate VDM for the OData service provided by S/4 HANA Cloud (which is not in API hub). The generated VDM class shows errors, in particular, it has an error with UUID set and get method, and the TRUE property. I attached the metadata edmx.xml here.

回答1:

It turned out that the problem was missing Lombok configuration.

As this question is asked multiple times I will give a bit more comprehensive answer than just "configure it", answering the most common questions.

What is Lombok?

According to their website:

Project Lombok is a java library that automatically plugs into your editor and build tools, spicing up your java. Never write another getter or equals method again, with one annotation your class has a fully featured builder, Automate your logging variables, and much more.

More specifically Lombok allows you to add annotations to your code which will generate boilerplate at compile time.

So, taking @EqualsAndHashCode as an example: This will generate, as the name implies, valid equals(Object) and hashCode() methods for the annotated class.

See the overview page for a full list of annotations.

What are you using Lombok for?

We use the following annotations in our OData VDM Generator (not a full list, this might also change in the future):

• @Builder
• @ToString
• @EqualsAndHashCode
• @Data

The last annotation brings in, besides others, the @Getter annotation which generates all necessary getters at compile time.

How do I compile my code with Lombok/Display it in my IDE?

As described directly by Lombok and our blog post you just need the Lombok dependency (org.projectlombok:lombok) with scope provided on your classpath.

To view the code in your IDE without any build issues you need to setup your IDE accordingly, see the Lombok guides for that.
