Maven Jaxb插件无法从目标文件夹生成类

Question

I try to copy an xsd file from a maven dependency and put it into target folder with others xsd files of my project and after that i wante to generate the jaxb classes but it can't generate them in the same time. When i make only the code of xsd file of the dependency, it can generate the jaxb classes but for the xsd files of my project it can't.

    <plugin>
     <!-- copy the xsdl files of my current project into the target folder-->

Answer 1

maven-jaxb2-plugin runs in generate-sources phase by default. You unpack your schemas in generate-resources . Schemas are just not yet there when you try to compile them.

To debug such problems run mvn -X clean install and check the logs.
