问题描述
我有两个Maven项目: 项目API project-impl
I have two maven projects: project-api project-impl
project-impl的POM指定了对project-api的依赖.顶级聚合pom列出了模块project-api和project-impl.
project-impl's POM specifies a dependency on project-api. The top level aggregation pom lists modules project-api and project-impl.
如果我在顶层运行编译,则依赖关系可以正确解析.如果我在project-impl上运行编译,则找不到依赖项project-api.我如何设置maven,以便当project-impl进行编译时,它首先进行编译并收集其对其他项目的依赖关系?
If I run compile at top level, the dependencies resolves correctly. If I run compile at project-impl, then it can't find dependency project-api. How can I set up maven such that when project-impl compiles, it first compiles and collects its dependencies on other projects?
推荐答案
您只能在根项目中执行此操作
you can only do that from the root project
mvn -pl child -am
这将构建您的子项目以及所有依赖项在同一棵树中.通常,当您有一个多模块项目时,应该始终从父级而不是从子级进行构建.如果只想构建一个或两个子项目,请执行以下操作:
this will build your sub project and also all dependencies in the same tree. in general, when you have a multi module project, you should always build from the parent, never from the child. And if you only want to build one or two child projects, do this:
mvn -pl child
OR
mvn -pl child2,child3
(已构建项目child2和child3,但未构建项目child1和child4)
(projects child2 and child3 are build, but child1 and child4 aren't)
