使用 lombok 1.16.6 版本的 lombok。从命令行构建(mvn clean install)时，我收到此错误:

如 https://projectlombok.org/mavenrepo/ 所述，你应该定义对 lombok 的依赖与 provided范围。如下例

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