Maven 多模块项目，不解决依赖关系

Question

我有一个无法编译的多模块 Maven 项目。我的本地网络上有一个 Nexus 存储库，它正在工作(IntelliJ Idea 能够解决我仅驻留在该存储库中的依赖项)，并且我正在通过 Jetbrains TeamCity 构建。我相当肯定 TeamCity 正在工作，因为我设置的其他几个构建配置仍然有效(使用相同的 settings.xml)。对于可能导致问题的原因，我有点茫然。这是我的pom文件:

我得到的错误是:

我在尝试调试时不知所措……有人有什么建议吗？

Answer 1

有几种方法/工具可以解决此类问题。

对于这个“无法解决依赖关系”错误，构建日志中几乎总是有更详细的错误消息和/或堆栈跟踪。 Maven 日志实际上非常冗长，以至于必须在构建失败后的几个屏幕上搜索“根”错误消息。

使用 -X 重新运行构建旗帜。这里是 documentation of Maven command line switches

另一种选择是使用 mvn dependency:tree检查传递依赖的完整图。 mvn help:effective-pom是另一个有用的工具，它在考虑您的 settings.xml、任何事件配置文件等之后打印出 pom.xml。同样 mvn help:active-profiles
