How can I tell jaxb / Maven to generate multiple schema packages?

Question

Example:

       
       
           org.jvnet.jaxb2.maven2         


        

Answer 1

I had to specify different generateDirectory (without this, the plugin was considering that files were up to date and wasn't generating anything during the second execution). And I recommend to follow the target/generated-sources/ convention for generated sources so that they will be imported in your favorite IDE automatically. I also recommend to declare several execution instead of declaring the plugin twice (and to move the configuration inside each execution element):

  org.jvnet.jaxb2.maven2
  maven-jaxb2-plugin
  0.7.1
  
    
      schema1-generate
      
        generate
      
      
        src/main/resources/dir1
        
          shiporder.xsd
        
        com.stackoverflow.package1
        ${project.build.directory}/generated-sources/xjc1
      
    
    
      schema2-generate
      
        generate
      
      
        src/main/resources/dir2
        
          books.xsd
        
        com.stackoverflow.package2
        ${project.build.directory}/generated-sources/xjc2
      
    
  

With this setup, I get the following result after a mvn clean compile

$ tree target/
target/
├── classes
│   ├── com
│   │   └── stackoverflow
│   │       ├── App.class
│   │       ├── package1
│   │       │   ├── ObjectFactory.class
│   │       │   ├── Shiporder.class
│   │       │   ├── Shiporder$Item.class
│   │       │   └── Shiporder$Shipto.class
│   │       └── package2
│   │           ├── BookForm.class
│   │           ├── BooksForm.class
│   │           ├── ObjectFactory.class
│   │           └── package-info.class
│   ├── dir1
│   │   └── shiporder.xsd
│   └── dir2
│       └── books.xsd
└── generated-sources
    ├── xjc
    │   └── META-INF
    │       └── sun-jaxb.episode
    ├── xjc1
    │   └── com
    │       └── stackoverflow
    │           └── package1
    │               ├── ObjectFactory.java
    │               └── Shiporder.java
    └── xjc2
        └── com
            └── stackoverflow
                └── package2
                    ├── BookForm.java
                    ├── BooksForm.java
                    ├── ObjectFactory.java
                    └── package-info.java

Which seems to be the expected result.
