Please post a link to a full sample project on GitHub. It should be minimal, but complete, so I can reproduce the problem. This is called an MCVE. Thank you.

[finalcreator]

for simplicity, do we have example for "maven configure" for lombok&aspectj, and jetty&aspectj? (java 11 or later)

[kriegaex]

I asked you for an MCVE. So the answer cannot be that you ask me for one instead. If you like to get help and think there is a bug in the plugin, you need to make it easy for me to reproduce your problem, not for me to create a build-to-order MCVE for you. Feel free to hire me if you need that kind of service, though.

The actual situation is that the project dependencies are more complex and there is no way to simplify them, so I think if there is a standard reference project, maybe I can solve it myself. That's why I asked if there were any relevant examples.

[finalcreator]

The error is: The package org.w3c.dom is accessible from more than one module: , java.xml

I tried to add -add-exports but didn't work, is this configure correct?

--add-exports java.xml/org.w3c.dom=ALL-UNNAMED

That statement is unworthy of a developer. You can always simplify. Just strip off as much as possible, until only as much is left as is necessary to reproduce the problem. If I cannot reproduce your problem, I cannot help you. I do not feel so inclined to try and guess what kind of undisclosed situation you might have. I am closing this question as invalid. If you change your mind and provide an MCVE, we can re-open it.
