How to export all packages from Java 9 module?

Dmitriy Dumanskiy :

Right now, for every module I have, I need to explicitly specify packages I want to export. For example:

module core {
    exports cc.blynk.server.core;
    exports cc.blynk.server.core.protocol.handlers.decoders;
    exports cc.blynk.server.core.protocol.handlers.encoders;
}

However, it is not very convenient. I would like to do something like that:

module core {
    exports cc.blynk.server.core.*;
}

Is there any way to do that? Where this limitation comes from?

Naman :

The usage of

module core {
    exports cc.blynk.server.core.*;
}

is discouraged since this could majorly lead to conflicts in the different packages exported from different modules which defies the purpose of modularising the code.

Additionally quoting from one of the threads:

The packages exported by a module are meant to be a stable API that consumers can rely on. For this reason, we make the module author spell out the exported packages explicitly. This also dials down the likelihood of multiple modules needlessly exporting the same package. Additionally, it avoids the confusion that would occur if com.abs.* was exported without qualification while com.abs.foo was exported with qualification.
