I've read and performed all the exercises in the Jigsaw quickstart
I also notice that all my existing Maven/Gradle/SBT Java Projects seem to work as normal under Java 9 without any changes or benefits. Nothing is defining or using Java Jigsaw Modules.
Is the normal Java/JVM world of Maven/Gradle/SBT going to adopt Jigsaw in a more noticeable way? Are all the libraries and frameworks of the JVM world going to use Jigsaw? Is there a reason or benefit over the Maven-dependency system that exists today? Is there any point or benefit for normal Java developers to use Jigsaw at all?
EDIT: I've read several StackOverflow questions with these search terms and none of them addressed my question. The linked StackOverflow question is from well over a year ago about an error with Maven 3.3 against early builds of JDK 9. That is completely irrelevant. I'm not getting errors. Also, Maven 3.5 and the final JDK 9 are out at the time of this posting.
