当我尝试将Intellij创建的项目导入Eclipse时，会出现名义错误，导入后，每当我尝试保存文件更新或更新项目时，也会提示相同的错误。我搜索了很多地方，发现这个问题实际上在互联网上非常频繁，但据我所知，没有一个单一的工作解决方案。因此，我必须自己提出这个问题才能得到更多的关注 - 也许来自那些真正了解问题并且也有解决方案的人。所以这里有一些关于我的工作环境的必要信息：Eclipse Neon，Windows 7，以及完整的堆栈跟踪：

我通过将父pom.xml中的绝对路径更改为相对路径来解决了这个问题。绝对路径无效的原因是Eclipse不允许在项目外设置输出目录。参考：https://stackoverflow.com/a/27562184/4357087

您可以使用两个不同的POM文件。一种用于日食，另一种用于命令行。即：
mvn -f pom-build-ext-dir.xml ...
