Because with the jdk12 sake. Because JAXB-API is part of the java ee, not in the default class path in jdk12. From the beginning java jdk9 introduced the concept of the module, the module can use the command --add-modles java.xml.bind incorporated jaxb-api. You may also choose another solution, add the following in dependence maven inside, can solve this problem:
