Maven 如何为项目的子模块指定父POM？

有一个Spring项目，其中包含模块：

项目的

pom.xml

有一个父项：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <parent>
        <groupId>com.bni.wfcredit</groupId>
        <artifactId>bni-wfcredit-root</artifactId>
        <version>1.0-SNAPSHOT</version>
        <relativePath>bni-wfcredit-root</relativePath>
    </parent>

    <artifactId>bni-wfcredit</artifactId>
    <packaging>pom</packaging>
    <name>Bni wfcredit</name>
    <url>http://maven.apache.org</url>

    <modules>
        <module>bni-wfcredit-root</module>
  </modules>
</project>

---

那么如何指定父级呢？

多模块结构应该是这样的--

首先，检查父项目是否在本地存储库中？如果没有，那么您需要检查它并自己构建它

您需要向

添加一个空的

，以便它从存储库解析父pom

<parent>
   <groupId>com.bni.wfcredit</groupId>
   <artifactId>bni-wfcredit-root</artifactId>
   <version>1.0-SNAPSHOT</version>
   <relativePath></relativePath>
</parent>

com.bni.wfcredit
.
在编译时从配置的maven存储库加载父pom。不是根项目上的，也不是模块中的

要在本地安装父pom，需要在父pom项目上运行以下命令：

mvn安装

或者，如果您已经有了父pom项目jar

mvn安装：安装文件-Dfile=文件路径

有关更多信息，请参阅和（如何创建JAR并将其安装到本地存储库？
好的，我找到了解决方案（感谢大家的回答）：我将主项目的相对路径设置为：
bni wfcredit root/pom.xml
，并将其他模块的相对路径设置为
。/bni wfcredit root/pom.xml
（除了根模块：）
我的案例与往常不同：父模块与您提到的不同，但它是主项目下的一个模块！那么如何从外部pom指向模块
bni wfcredit root
？基于给定的结构，不应定义relativePath，因为默认值为
。/pom.xml
。。。！
