How can I publish an existing plugin jar to the plugin portal?

Hi! Sorry, I was on leave and just got back today.

You should be able to add the javadoc jar to the archives configuration. See the user guide for details on how to do that, but it will probably look something like:

artifacts {
    archives javadoc // assuming using the default javadoc task
}

This is a known issue. In the meantime, I have updated the description manually for now, but don’t have access to the tags used when publishing the latest version. Let me know here if you need them changed.

Regards

Tom
