Add module-info.java

[cowwoc]

JPMS users who depend on this library get the following build warning:

[WARNING] requires transitive directive for an automatic module

Can you please publish a multi-release or exclusive JAR with module-info for users of Java 9+?

[cowwoc]

I tried ignoring the warning and ended up with an error later on in the build:

[ERROR] the unnamed module reads package org.checkerframework.dataflow.qual from both org.checkerframework.dataflow and org.checkerframework.checker.qual

and even more annoyingly:

[ERROR] the unnamed module reads package com.google.errorprone from both error.prone.core and error.prone.annotation

Is there a workaround for this (without dropping the use of JPMS in my own library)? Or am I stuck until module-info is added here?

[cowwoc]

It looks like this library cannot be used at all with JPMS due to the existence of split packages. See #1210

A couple of notes:

We only support JDK 11 and newer at this point, so we could add a module-info without the need for multi-release jars.

The annotations jar is now using Automatic-Module-Name: 5793bca

@cowwoc There's a PR for this now at #4311.

I think a little more work is needed here: #4314
