Maven Jaxb生成的包名称是倒退的

我创建了一个简单的Maven项目,该项目使用Jaxb将模式编译为Java文件。一切似乎都在起作用,但问题是生成的包名是倒退的:

Windows Explorer

我的Xml架构如下所示:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://com.mystuff.jaxb.inventorycontrol.inventorydata"
    targetNamespace="http://com.mystuff.jaxb.inventorycontrol.inventorydata" elementFormDefault="qualified" version="1.0.0">
    ....
    ....      
    <xs:complexType name="InventoryItemListType">
        <xs:sequence>
            <xs:element name="Item" type="InventoryItemType" />
        </xs:sequence>
    </xs:complexType>        
</xs:schema>

命名空间 http://com.mystuff.jaxb.inventorycontrol.inventorydata 以com开头,以inventorydata结束,所以我认为这将是包/文件夹顺序:

com\mystuff\jaxb\inventorycontrol\inventorydata

但我的倒退结束了:

inventorydata\inventorycontrol\jaxb\mystuff\com\

不确定在我的pom.xml上粘贴一些是否有点过分,但我猜它不会受到伤害。

这是我的根pom:

<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">

            <plugins>
                ....
                <plugin>
                    <groupId>org.jvnet.jaxb2.maven2</groupId>
                    <artifactId>maven-jaxb2-plugin</artifactId>
                    <version>${maven-jaxb2-plugin-version}</version>
                    <configuration>
                        <catalog>src/main/resources/catalog.xml</catalog>
                        <catalogResolver>org.jvnet.jaxb2.maven2.resolver.tools.ClasspathCatalogResolver</catalogResolver>
                        <extension>true</extension>
                        <schemaDirectory>${basedir}/src/main/resources/xsd</schemaDirectory>
                        <schemaIncludes>
                            <include>*.xsd</include>
                        </schemaIncludes>
                    </configuration>
                    <executions>
                        <execution>
                            <goals>
                                <goal>generate</goal>
                            </goals>
                        </execution>
                    </executions>
                </plugin>
            </plugins>
        </pluginManagement>    
    </build>

    <modules>
        <module>inventorydata</module>
    </modules>

</project>

这是具有架构的模块的pom:

<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">
    ....
    <packaging>pom</packaging>
    <parent>
        <groupId>com.mystuff.jaxb</groupId>
        <artifactId>inventorycontrol</artifactId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <groupId>com.mystuff.jaxb.inventorycontrol</groupId>
    <artifactId>inventorydata</artifactId>
    ....
    <build>
        <plugins>
            ....
            <plugin>
                <groupId>org.jvnet.jaxb2.maven2</groupId>
                <artifactId>maven-jaxb2-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
</project>

_Update _

当我创建项目时,我基本上将架构/ pom文件从旧项目复制/粘贴到这个新项目。旧项目架构如下所示:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://www.cmv.com/java/maven/jaxb/schemas/core/types"
    targetNamespace="http://www.cmv.com/java/maven/jaxb/schemas/core/types" elementFormDefault="qualified" version="1.0.0">
    ....
    <xs:complexType name="PoundsWeightType">
        <xs:sequence>
            <xs:element name="Value" type="PositiveFloat" />
        </xs:sequence>
        <xs:attribute name="Units" type="UnitsEnum" use="required" fixed="Lbs" />
    </xs:complexType>
</xs:schema>    

我为该项目生成的包是:

com\cmv\java\maven\jaxb\schemas\core\types

Project With Correct Order

这就是我所期望的。

Java组件,软件包等...使用反向dns命名。您正在以DNS格式指定命名空间,这意味着您打算将其撤消。

作为网址写出的名称空间com.mystuff.jaxb.inventorycontrol.inventorydata将是:http://inventorydata.inventorycontrol.jaxb.mystuff.com
