Question

我正在尝试通过研究this tutorial来学习hyperjaxb。我按照所有说明一直到标题部分What was Generated?。这包括以下步骤：

1.) download the <a href="http://confluence.highsource.org/display/HJ3/Downloads">Basic Project Template for Hibernate and Maven</a>
2.) unzip the file
3.) install the xml and xsd files in the assigned locations
4.) open up `cmd.exe`
5.) navigate to the directory of the unzipped root folder
6.) run mvn clean install

但没有产生任何结果。没有/generated-sources/xjc目录，也没有PurchaseOrderType.java。我对整个目录结构进行了关键词搜索，以确认在运行mvn clean install后这些资源不存在。我还将目录结构导入到一个新的eclipse maven项目中，并在新的eclipse maven项目中尝试run as...maven clean和run as...maven build，但同样缺乏结果。

如何让本教程生成预期生成的文件？

另外，有没有更好的方法从xsd生成JPA实体？

修改

根据@ kapep的建议，我尝试了mvn generate-sources并获得了以下结果：

然后我再次尝试了mvn clean install，得到了以下结果：

您可以在打印屏幕中看到org.apache.maven.plugins:maven-compiler-plugin缺少的警告。我在我的机器上的.m2存储库中找到了相应的文件夹并将其删除，然后在eclipse中执行了maven update project重新下载库。然后我做了另一个mvn clean install，并得到了相同的结果。没有生成任何内容，没有java文件，没有generated-sources目录。没有。

我还能尝试什么？

第二次编辑：

教程应用程序仍然不会生成目标文件，但是，我能够通过将pom的maven-compiler-plugin部分更改为以下内容来消除打印屏幕中的警告消息：

<plugin>
    <inherited>true</inherited>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>2.3.2</version>
    <configuration>
        <source>1.6</source>
        <target>1.6</target>
    </configuration>
</plugin>

请注意，除了指定版本之外，我还根据@Todd的建议{{source将target和1.5从1.6更改为{{1}} 3}}。我假设这些是指JDK版本。我的安装使用JDK 1.6。我不知道这是否会造成任何问题。

我还能尝试什么？

Answer 1

<强>更新

最后看来OP正在项目的根目录中寻找生成的类而不是target\generated-source\xjc，尽管tutorial明确说明了要查看的位置：

如果您浏览目标/ generated-sources / xjc目录，您将找到生成的java文件很少，例如PurchaseOrderType.java。

再一次，我没有得到这个。适合我。

我的步骤是：

将hyperjaxb3-ejb-template-basic-0.6.0-maven-src.zip解压缩到某个位置
将schema.xsd放入src/main/resources
将po.xml放入src/test/samples
mvn clean install

这就是我得到的，美好而干净的：

我不知道为什么它不适合你。请发布mvn clean install -X和dir /b/s日志，以便我检查您的设置。
