SBT中已发布的程序集包中的未解析依赖项

Question

在我的项目中，根目录下有3个子项目。 build.sbt如下。 proj_C依赖于proj_A和proj_B。如果我用下面的命令创建了程序集proj_C包。它的成功和组装包可以在其他项目中导入。

sbt“project proj_C”程序集

如果我使用“sbt publish”发布，因为我在proj_C设置中定义了addArtifact，也会生成一个程序集jar包然后发布。但是当我尝试编译另一个导入这个程序集jar的项目时，它将低于错误

[错误]未解决的依赖项：proj_A; 1.0.0：未找到

build.sbt的一部分如下。任何人都能指出我的错误吗？非常感谢！
