如 https://projectlombok.org/mavenrepo/ 中所述，您应该定义对 lombok 和 provided 范围的依赖。如下例

<dependencies> 
    <dependency> 
        <groupId>org.projectlombok</groupId> 
        <artifactId>lombok</artifactId> 
        <version>1.16.6</version> 
        <scope>provided</scope> 
    </dependency> 
</dependencies>
