javax.smartcardio in Java 9, 10, 11, 12… etc

Question

What happened to the javax.smartcardio library from Java 9 onwards? Is there an alternative or some way to obtain it in JAR?

Answer 1

After some hours searching on the web, thanks to the answer above, and as far as I understand, Java 9 and later are modular, which is a language improvement planned some years ago. Also, after the new Oracle rules update, some packages were moved from the SE to the EE version.

The module smartcardio is now optional, but it is still included in the SE. So if you want to use it, you have to require it in a module-info.java.

Example:

I have created this file in my maven project: src/main/java/com/module-info.java

module com.chema.nfc_rfid_reader_writer {
    requires java.smartcardio;
    exports com.chema.nfc_rfid_reader_writer;
}

And that's all
