Question

在使用 IntelliJ 的多模块项目中，我的 Maven 依赖项有问题。

以下是我的maven模块的结构： (1) venus 是根模块。 (2) architect 是 architect-com 模块的父模块。 (3) actions-com是actions模块的子模块，services是actions模块的父模块。 (4) architect 和 services 是根模块的直接子模块

- venus
  - architect
    - architect-com
      - src [java classes here]
  - services
    - actions
      - actions-com
         - src [java classes here]

架构师、服务和操作模块没有 src 文件夹（我删除了它们，因为我认为父模块不需要 src 文件夹。）

这里是模块的 POM。

actions-com 模块导入 architect-com，如上面的 pom 所示。当我编译 actions-com 模块时，出现以下错误：

C:\3_projects\venus\services\actions\actions-com>mvn clean compile

以下是我的 .m2 存储库的路径，其中构建了 Architect-com。这是快照文件夹的内容

C:\Users\user\.m2\repository\co\shock\venus\architect\architect-com\1.0-SNAPSHOT
   - _remote.repositories
   - architect-com-1.0-SNAPSHOT.jar
   - architect-com-1.0-SNAPSHOT.pom
   - maven-metadata-local.xml

我用谷歌搜索了一整天，但找不到任何解决方案。我希望有人指出正确的方向。

我做错了什么？

Answer 1

看错误msg的最后一句：Could not find artifact co.shock:venus:pom:1.0-SNAPSHOT

services 包含：

    <parent>
        <artifactId>venus</artifactId>
        <groupId>co.shock</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>

但金星包含：

    <groupId>co.shock</groupId>
    <artifactId>jupiter</artifactId> <!-- should be 'venus' -->
    <version>1.0-SNAPSHOT</version>

你只是把行星搞混了。 :)
