docx4j 8.1.7 and 11.1.7 are each now in Maven Central.
The only real difference between the two is that the 11.1.7 jars include module-info.
For docx4j 11.1.x users, 11.1.7 is important; it rolls up the changes in 8.1.4 to 8.1.7
8.1.7 is just a minor release (if you are already using 8.1.5 or 8.1.6 which you should be, for docx or xlsx respectively).
- OpenDoPE: fix handling of count>0 when OpenDoPEHandler.ENABLE_XPATH_CACHE
- docx4j-export-fo: move to FOP 2.4
To use 8.1.7 via Maven, just add one and only one of docx4j-JAXB-Internal, docx4j-JAXB-MOXy,
or docx4j-JAXB-ReferenceImpl to your pom. https://search.maven.org/search?q=g:org.docx4j
For 11.1.7 via Maven, choose docx4j-JAXB-MOXy
