JDK12 - "com.sun.tools" not accessible [message #1818211] Tue, 10 December 2019 09:48 Go to next message

I'm trying to import in Eclipse (2019-09 R (4.13.0)) a Maven project which uses the JDK 12 and makes use of classes from the com.sun.tools package.
Everything compiles fine, except for the classes from that package, which are found but not accessible (the compiler raises the error "The package com.sun.tools.javac.api is not accessible").
How to fix this?

Thanks

Oracle really doesn't want you to access classes in com.sun.tools.javac.api, the corresponding module-info for jdk.compiler declares:
    exports com.sun.tools.javac.api to
        jdk.javadoc,
        jdk.jshell;


Ergo, the package is accessible only to those two modules.

If you must break these rule (and take all responsibility on yourself), see:
- https://help.eclipse.org/2019-06/index.jsp?topic=%2Forg.eclipse.jdt.doc.user%2Freference%2Fref-properties-build-path.htm&anchor=module-dependencies
- https://www.youtube.com/watch?v=UUQoQtKgaWc&list=PLy7t4z5SYNaT_yo5Dhajb9i-Pf0LbQ3z8&index=24

(look out for the parts about exports).
