我在Eclipse之外构建我的maven项目时遇到了麻烦。在eclipse中，我可以毫无问题地完成它，所有依赖关系都得到了解决。
我得到的错误是它无法从依赖项目中找到jar文件：

最终目标是让这个在jenkins上运行，但第一步是让它在终端上运行。
更新
我清理（删除）了mydomain存储库中编译源的目录，然后重新启动CommonLibraries的安装。那很有效！
之后我遇到了错误，但它们与我在主文件夹中依赖于TestNG的测试类有关。它现在有效。
答案 0 :(得分：0)
为负责com.mydomain：CommonLibraries：jar：0.0.1-SNAPSHOT工件的项目运行“mvn clean install”，以便在Maven存储库中创建它。
您看到的行为是因为m2e可以直接从Eclipse项目中解析工件。
