m2e显示jaxb2 maven插件schemagen目标的执行错误

我使用maven和jaxb2 maven插件版本2.2，通过调用目标schemagen来生成xsd

无论是从命令行运行maven，还是在eclipse中使用m2e运行maven，一切都可以正常工作。到目前为止还不错

不幸的是，在eclipse中，pom文件中显示了一个错误/异常：

Execution serviceConfigs-schemagen of goal org.codehaus.mojo:jaxb2-maven-plugin:2.2:schemagen failed. (org.codehaus.mojo:jaxb2-maven-plugin:2.2:schemagen:serviceConfigs-schemagen:generate-resources)

如果执行Maven-->更新项目，错误会消失一段时间，但一旦生成项目，错误就会再次出现

有人知道如何获取rip或此错误消息吗

提前谢谢

似乎与该版本插件中的一个bug有关。更新插件到版本2.4已经为我解决了这个问题
