我正在转向 Maven 多模块构建。

我的项目结构如下：

MyProject
|-->MyProject-Core
|   |->pom.xml (packaging jar)
|-->MyProject-Assets
|   |->pom.xml (packaging jar)
|-->MyProject-Libs
|   |->pom.xml (packaging jar)
|-->pom.xml (packaging pom, aggregator)

这MyProject是一个 Maven Eclipse 项目，由 M2E 构建。

我将 MyProject-Core/src/main/java 添加为 Eclipse 源文件夹，但由于我将父 pom 中的依赖部分更改为 dependencyManagement，因此我从 Eclipse 中得到了构建错误。手动调用mvn package仍然可以正常工作。

如何配置 Eclipse 以正确解决核心 pom 的依赖关系？

我仍然可以将依赖项添加到父 pom 作为范围：提供，但这是最好的解决方案吗？

我尝试了很多配置，但 M2E 无法将子模块识别为自己的项目，或者子模块的更改未被父模块项目识别。

现在我创建了几个 Eclipse 项目，每个 Maven 项目一个，它工作正常。
