SWIG should produce identical code when generated on all platforms. There
is nothing in the Java layer that is platform specific so you can use just
one jar file on all platforms. There is a very small amount of
platform/compiler specific code within C macros in the generated code.

- Can we compile the swig jar binding file to ignore non used C++ methods?

Use %ignore.
