jaxb2-maven-plugin只执行第一次执行

Question

我正在尝试使用jaxb-
maven插件使用JAXB将多个XSD转换为不同包中的POJO。我已将其设置为使用多个执行块，然后执行第一个执行块，然后出现一条消息：模式或绑定文件中未检测到更改

这是我pom.xml的摘录：

        </execution>        
        </executions>
    </plugin>
    ...

....

这是我收到的错误消息：

如果我交换执行块，则第一个总是执行，其余两个块得到相同的消息。

关于如何解决这个问题的任何想法？

Answer 1

通过升级到版本1.6进行了修复

<plugin> 
    <groupId>org.codehaus.mojo</groupId> 
    <artifactId>jaxb2-maven-plugin</artifactId> 
    <version>1.6</version> 
</plugin>

和

<!-- JAXB GENERATOR PLUGIN -->
<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>jaxb2-maven-plugin</artifactId>
    <version>1.6</version>
    ....

在1.6版中修复，在1.5版中，所有执行块都使用相同的staleFile：http
