I am trying to migrate my project to JDK 20 ( I am new to java modularization) The project is very simple , it is a JAXB compile utility to have Google Kml Classes. I created the module-info.java as :
module View {
requires java.base;
requires java.xml.bind;
}
And the maven compiler in pom.xml is as :
<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

The problems are :
- in module-info.java 'requires java.xml.bind' report message 'module not found'
- in generated classes all import that involves 'javax.xml.*' package report message 'package javax.xml.bind is not visible (package javax.xml.bind is declared in the unnamed module, but module View does not read it)'
ofcourse in project dependencies I can see the jaxb-api-2.3.1.jar
then where I am doing wrong ?
Now , just a cleaning of pom avoiding dependencies with version 3.0.2.Now I am just:
<?xml version="1.0" encoding="UTF-8"?>

Now I have just dependency from jaxb-api 2.3.1 (containing javax.xml.bind module) and a simple class that need some classes from javax.xml.bind but stil two problem are here!
