jaxb2-maven-plugin throws Exception when maxOccurs

Question

When I run the jaxb2-maven-plugin on a legacy xsd it throws this Exception:

Current configuration of the parser doesn't allow a maxOccurs attribute value to be set greater than the value 5,000

Googling this error shows that this is a limit that was put on jaxp for security purposes. It can be disabled in code like this

SAXParserFactory spf = SAXParserFactory.newInstance();
spf.setFeature(XMLConstants.FEATURE_SECURE_PROCESSING,false);

but I need to do this in maven. Also, xjc has a -nv switch to turn off this validation and that looks like the way to go. I can't change the xsd.

What's the syntax for passing the -nv switch in the jaxb2-maven-plugin?

Answer 1

My colleague Vic Ganora found the answer in the source code for the jaxb2-maven-plugin. In the <plugin>...<configuration> element you need to add

 <laxSchemaValidation>true</laxSchemaValidation>.
