Maven使用eclipse構建多模塊

Question

我正在轉向maven多模塊構建。

我的項目結構如下所示：

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

的MyProject是Maven的Eclipse項目和M2E建成。

我加入了MyProject的核心/ src目錄/主/ Java作爲Eclipse的源文件夾，但因爲我改變了依賴部分在父POM以dependencyManagement，我從Eclipse構建錯誤。手動調用mvn package仍然正常工作。

如何配置Eclipse來正確解析核心POM的依賴？

我仍然可以添加依賴關係父POM的範圍：提供的，但是這是最好的解決辦法？

Answer 1

我嘗試了很多配置，但M2E不認子模塊作爲子模塊自己的項目或變化是沒有被父模塊項目識別。

現在我創建了幾個Eclipse項目，每個Maven項目都有一個，它工作正常。
