A given Java program should produce identical results regardless of the underlying CPU, operating system, or Java compiler. This idea is not new; languages such as C and C++ have provided the opportunity for this level of portability for many years. However, C and C++ also provide numerous ...

It may be an option to use theannotationProcessorPathsconfiguration option of the maven-compiler-plugin rather than an optional dependency. How do I create a DataEnum type? First, you define all the cases and their parameters in an interface like this: ...
