【问题描述】：
我无法在 Eclipse 之外构建我的 maven 项目。在 Eclipse 中，我可以毫无问题地做到这一点，并且所有依赖项都已解决。
我得到的错误是它无法从依赖项目中找到jar文件：

最终目标是让它在 jenkins 上运行，但第一步是让它在终端上运行。
更新：
我在 mydomain 的存储库中清理（删除）了包含已编译源的目录，然后重新运行 CommonLibraries 的安装。那行得通！
在那之后我得到了错误，但它们与我在主文件夹中有依赖于 TestNG 的测试类有关。现在可以了。
【问题讨论】：
-
所以 jar com.mydomain:MeasurementProcessor:jar:0.0.1-SNAPSHOT 存在于本地 m2 存储库中？
-
在构建项目之前，您是否尝试过安装
com.mydomain:CommonLibraries？ -
完全不相关，但作为 HikariCP 的作者，我看到您运行的是 1.2.8。我们修复了该版本和当前 1.3.0 之间的几个严重错误。我建议更新您的依赖项。
-
@NiksTyagi：我假设您的意思是 CommonLibraries.jar，是的。阅读您的评论后，我删除了存储库中的奇数版本并运行 mvn install，它创建了 jar（也回答了@Joao）。 MeasurementProcessor 的 jar 未显示。我得到一个不同的错误，我会在上面更新。
-
@brettw：谢谢，更新依赖。我将使用 [1.0.0,2.0.0) 作为版本，所以我跟上。这安全吗？
