1. 父项目打包方式为 pom  
 

<packaging>pom</packaging>

2. 父项目版本配置

    <properties>
        <maven.compiler.source>17</maven.compiler.source>
        <maven.compiler.target>17</maven.compiler.target>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <lombok.version>1.18.16</lombok.version>
    </properties>

3. 父项目依赖-Lombok为例

    <dependencies>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
        </dependency>
    </dependencies>

4. 依赖管理器

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.projectlombok</groupId>
                <artifactId>lombok</artifactId>
                <version>${lombok.version}</version>
            </dependency>
        </dependencies>
    </dependencyManagement>

5.在子模块就可以直接使用lombok了
