This is my first time trying to turn a Java project into an executable. I learned that I need to create an executable jar file first. I’m using NetBeans IDE 22, when I right click in the project in “Clean and Build” to build the jar it gives me this error:

An annotation processor threw an uncaught exception.
Consult the following stack trace for details.

My project runs fine in the IDE, I just can’t build the jar file. I’m also using persistence from the EclipseLink (JPA 2.2) library, and the error seems to point to that. It gives me “Unknown element: “ephemeral””. I don’t even know what “ephemeral” is, I certainly didn’t code this word, so it’s seems something internal in the library. There’s also nothing related to “ephemeral” in the persistence.xml file. I don’t know what details I can give more, because I don’t even know where this error is coming from in the first place.

I tried searching for answers online, but didn’t find anything.
I’m also using JDK 22 and my project is with Ant, idk if this is relevant.

Thanks in advance!!
