在路径C：\ PMX \ checkout \ components \ promomax-all_webapps_component我有这个文件：pom-aggregator-packaging.xml
文件pom-aggregator-packaging.xml包含一些使用turtoiseCVS检出的模块。
当我进入cmd到路径C：\ PMX \ checkout \ components \ promomax-all_webapps_component并输入 mvn -f pom-aggregator-packaging.xml clean install 时返回的错误是：< / p>

pom-aggregator-packaging.xml的内容是：
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>com.company_name.app_name</groupId>
<artifactId>monitoring-pom-aggregator</artifactId>
<version>1.0.0</version>

<name>NameOfTheApp Engine Server Component Pom Aggregator</name>
<modules>
...
<module>../../bundles/promomax-spring_aspects</module>
...
</modules>
</project>
请帮助我解决此错误？
如果在pom-aggregator-packaging.xml中我改变了
<module>../../bundles/promomax-spring_aspects</module>给出绝对路径：
<module>C:/PMX/checkout/components/promomax-all_webapps_component/bundles/promomax-spring_aspects</module>
然后再次运行命令 mvn -f pom-aggregator-packaging.xml clean install ，新错误是：
[ERROR] FATAL ERROR
[INFO] ------------------------------------------------------------------------

答案 0 :(得分：1)
非常肯定，如果你更换
<module>../../bundles/promomax-spring_aspects</module>
与
<module>../../components/promomax-all_webapps_component/bundles/promomax-spring_aspects</module>
它会起作用。
但是你的设置对我来说似乎并不干净。引用模块通常是从父POM完成的，它应该位于比子poms更高级别（文件系统）上。
所以更像是
除非你在父母/子女的背景下，否则你不应该依赖相对路径。
