An example Java 11 project using Maven and JUnit 5 to demonstrate XML validation

Javadoc here:

1. https://docs.oracle.com/en/java/javase/13/docs/api/java.xml/javax/xml/validation/package-summary.html

Goals

• Learn how to setup Java 13 in Travis

• Learn how to create a module in Java >= 11 and how to have Maven running tests properly (right now, when module is defined, test will fail on running mvn verify due to lack of classes visibility)

• Move to Java 13 and play with new String literals

• Create an example for safe XML validation using Java (at least so that Sonar does not complain ... however, considering JAXP documentation)

  • https://docs.oracle.com/javase/8/docs/technotes/guides/security/jaxp/jaxp.html
  • https://docs.oracle.com/javase/tutorial/jaxp/properties/backgnd.html

• My use case:

  • run multiple validations against the same schema over and over
  • It would be okay to keep the schema in memory, it is pretty large
  • requires input (a) from file and (b) from string
  • Instead of exceptions as result types, something more suitable shall be there as all processing shall happen within streams and completable futures
