JDK14 JPMS problem - module colesico.armario.mailer reads package org.simplejavamail.internal.modules from both org.simplejavamail.core and org.simplejavamail

[colesico]

Hi, here is my pom part:

<dependency>
            <groupId>org.simplejavamail</groupId>
            <artifactId>simple-java-mail</artifactId>
            <version>6.0.4</version>
</dependency>

module-info:

requires org.simplejavamail;
requires org.simplejavamail.core;

and app code:

 Email email = EmailBuilder.startingBlank()
            .from(mailerJob.getFromName(), mailerJob.getFromAddr())
            .to(mailerJob.getToAddr())
            .withSubject(mailerJob.getSubject())
            .withPlainText(mailerJob.getText())
            .buildEmail();

when try to compile application an error occurred:

module 'bla bla' reads package org.simplejavamail.internal.modules from both org.simplejavamail.core and org.simplejavamail

If remove (1) 'requires org.simplejavamail.core;' or (2) 'requires org.simplejavamail;' from module-info another error occuring:

for (1): package org.simplejavamail.api.email is not visible
for (2) package org.simplejavamail.mailer is not visible

It seams something wrong with the package exporting in simplejavamail jpms modules

Yikes, I don't have much experience with modules in Java, so right now your guess is as good as mine (probably better :P)

Hi. I have encountered the same issue when I expiremented with modules.

The problem imo is described here:
https://stackoverflow.com/questions/42358084/package-conflicts-with-automatic-modules-in-java-9

From my understanding is the issue that both jars provide the same packages.

Yet I'm also new to the module topic and was just expirementing with it on a private play around project.

To make good jpms support in my opinion it is need to do the following:

1. Eliminate package duplication in a modules
2. Add to all modules src/main/java/module-info.java (JMPS module declaration file )
3. Export all public packages from each module ("exports [package name]" declaration in module-info)
4. For module "simple-java-mail" add "requires transitive core-module" declaration to module-info to avoid exporting both modules in client code

Is there a plan to provide simple-java-mail JPMS conform?
