Maven：來自其他模塊的不可解析的進口POM

Question

它類似於Maven: Non-resolvable parent POM，但不一樣。

我有一個父POM

<groupId>group</groupId> 
<artifactId>parent</artifactId> 
<version>SNAPSHOT</version> 
<packaging>pom</packaging> 

<modules> 
    <module>module1</module> 
    <module>module2</module> 
    <module>module3</module> 
</modules> 

module1定義了一些dependencies使用dependencyManagement

子POM：module3/pom.xml試圖導入module1

<parent> 
    <artifactId>group</artifactId> 
    <groupId>parent</groupId> 
    <version>SNAPSHOT</version> 
    <relativePath>../</relativePath> 
</parent> 

<dependencyManagement> 
    <dependencies> 
    <dependency> 
     <groupId>group</groupId> 
     <artifactId>module1</artifactId> 
     <version>SNAPSHOT</version> 
     <scope>import</scope> 
     <type>pom</type> 
     <!-- 
     <systemPath>../module1</systemPath> 
     --> 
    </dependency> 
    </dependencies> 
</dependencyManagement> 

如果我嘗試建立父，它是好的

mvn validate 
[INFO] Scanning for projects... 
[INFO] ------------------------------------------------------------------------ 
[INFO] Reactor Build Order: 

... ... 

[INFO] parent ............................................ SUCCESS [0.128s] 
[INFO] module1 ........................................... SUCCESS [0.011s] 
[INFO] module2 ........................................... SUCCESS [0.009s] 
[INFO] module3 ........................................... SUCCESS [0.009s] 
... ... 
[INFO] ------------------------------------------------------------------------ 
[INFO] BUILD SUCCESS 

但是，如果我的孩子模塊中運行構建，它失敗

mvn validate 
[INFO] Scanning for projects... 
[ERROR] The build could not read 1 project -> [Help 1] 
[ERROR] 
[ERROR] The project group:module3:SNAPSHOT (/path-tp/project/module3/pom.xml) has 5 errors

什麼我已經試過

• 我會嘗試使用systemPath但它不支持import範圍。
• 我想嘗試從module3移動import範圍dependencies聲明父模塊，但它沒有抱怨圓依賴

如何建立/加載孤獨的子模塊module3，或者是還有什麼通過其他方式將多個子模塊拆分爲多個子模塊dependencyManagement？

Answer 1

當在父級工作時，Maven能夠解決模塊之間的依賴關係。

但是，如果你在模塊3內工作，它不知道module1是項目的同級模塊。

如果您想直接在模塊3內部工作，則需要先安裝模塊1。
