我正在使用maven和2.2版jaxb2-maven-plugin通过调用目标schemagen来生成xsd。
当我从命令行运行maven或使用m2e在eclipse中运行它时，一切都能找到。到目前为止一切顺利。
不幸的是，在Eclipse中，显示了pom文件中的错误/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)
org.apache.maven.plugin.PluginExecutionException: Execution serviceConfigs-schemagen of goal org.codehaus.mojo:jaxb2-maven-plugin:2.2:schemagen failed.

如果我执行Maven->更新项目，错误会消失一会儿，但是一旦我构建项目，它就会再次出现。
有人知道如何获取撕裂声或此错误消息吗？

似乎是该版本插件中的错误。将插件更新到2.4版已经为我解决了这个问题。
