Set up Multi-Module Maven Project with SpringBoot and React Sub-Modules
问题
我正在尝试设置一个包含SpringBoot和React应用程序的monorepo。目前，我的模块结构如下：
root
+-- backend
| +-- pom.xml
+-- frontend
| +-- pom.xml
+-- pom.xml
父级pom：
<?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>
<groupId>org.example</groupId>
<artifactId>multi-module-demo</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>pom</packaging>
<modules>
<module>frontend</module>
<module>backend</module>
</modules>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
</project>
frontend/pom：
<?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>org.example</groupId>
<artifactId>multi-module-demo</artifactId>
<version>1.0-SNAPSHOT</version>
</parent>
<artifactId>frontend</artifactId>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
</project>
backend/pom：
<?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>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>3.0.2</version>
<relativePath /> <!-- lookup parent from repository -->
</parent>
<artifactId>backend</artifactId>
<properties>
<java.version>17</java.version>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<maven.compiler.source>17</maven.compiler.source>
<maven.compiler.target>17</maven.compiler.target>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
当查看backend/pom.xml时，我有一个问题，父级不是我的父级pom，而是SpringBoot的pom。然而，这样做的话，我无法管理项目的版本。因为目前构建输出如下：
[INFO] Reactor Summary:
[INFO]
[INFO] multi-module-demo 1.0-SNAPSHOT ..................... SUCCESS [ 0.150 s]
[INFO] frontend 1.0-SNAPSHOT .............................. SUCCESS [ 0.784 s]
[INFO] backend 3.0.2 ...................................... SUCCESS [ 4.102 s]
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
您可以看到各个构件的版本不匹配。
我的问题是，我需要如何修改backend/pom以匹配frontend/pom？

Parent pom:

While looking at the backend/pom.xml, I have the issue that the parent is not my parent pom, but the SpringBoot pom. This way however, I could technically not manage e.g. the version of the Project. Because currently the build output is
[INFO] Reactor Summary:
[INFO]
[INFO] multi-module-demo 1.0-SNAPSHOT ..................... SUCCESS [ 0.150 s]
[INFO] frontend 1.0-SNAPSHOT .............................. SUCCESS [ 0.784 s]
[INFO] backend 3.0.2 ...................................... SUCCESS [ 4.102 s]
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
where you can see that the versions are not matching of each artifact.
My question is, how do I need to adapt the backend pom to match the frontend pom?

在进一步调查后，以下是我需要添加到我的父POM文件的内容：
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>3.0.2</version>
<scope>import</scope>
<type>pom</type>
</dependency>
</dependencies>
</dependencyManagement>
英文:
After some further digging, here's what I need to add to my parent pom:
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>3.0.2</version>
<scope>import</scope>
<type>pom</type>
</dependency>
</dependencies>
</dependencyManagement>
