Failed to execute goal org.codehaus.mojo:jaxb2-maven-plugin:2.5.0:xjc (xjc) on project: Prefix '' is already bound to ''

[UserBoi1]

Dear Mojohaus Team,

I am getting the following error upon building my project in Java 11:

[INFO] Created EpisodePath [XXXX/src/main/java/META-INF/JAXB]: true
[INFO] Ignored given or default xjbSources [XXXX/src/main/xjb], since it is not an existent file or directory.
[ERROR] Failed to execute goal org.codehaus.mojo:jaxb2-maven-plugin:2.5.0:xjc (xjc) on project XXXX: Prefix '' is already bound to ''

I have researched the issue thoroughly and implemented the suggestions I have found, but with no luck.

Considerations:

• I am trying to maintain compatibility with Java 8 and Java 11, so that my app can be built to Java 8 and runnable on both 8 and 11.
• I have adopted (JAXB 3.0.0) for this reason.
• The jaxb2-maven-plugin versions available to me are: 1.5.0, 2.3.0, 2.3.1, and 2.5.0 (can't use 3.2.0 due to older Maven).

Please let me know if there is anything I can clarify.
Any help much appreciated.
