For adding exports as I know there is two options:
option 1: public
Module.addExports
@CallerSensitive
public Module addExports(String pn, Module target) {
if (pn == null)
throw new IllegalArgumentException("package is null");
Objects.requireNonNull(target);
if (isNamed()) {
Module caller = Reflection.getCallerClass().getModule();
if (caller != this) {
throw new IllegalStateException(caller + " != " + this);
}
implAddExports(pn, target, true);
}
return this;
}
option 2: internal for java.base
jdk.internal.module.Modules.addExports(source, pn, target)
As you can see option 1 is useless, why?
because
/**
* If the caller's module is this module then update this module to export
* package {@code pn} to the given {@code target} module.
I think for all use cases we would have caller's module != this module
So this don't work.
Option 2 will fail since that is internal for java.base purpose only.
Is there other options? (non-command-line options)
