Question

我在Java中有一个包含两个模块的项目。

第一个模块是spring boot，我的控制器在这个模块中，我称之为Host Api。

第二个模块是maven模块，并将其称为命令层和该模块中的所有通用模型。

我的问题在这里，当要在两个模块之间进行引用（这意味着我的控制器使用通用模型）时，我的项目运行正常，但是当我clean compile install那个行家给我一个错误时

c:\userd\.m2\repository\project name为空时显示此错误

当我clean compile install再次给我不同的错误

您还已经为commandartifact项目执行了mvn install，将其安装到本地Maven存储库中。
