• 在 Java Spring Boot 项目中，使用上述配置，打包报如下错误

Unable to make field private com.sun.tools.javac.processing.JavacProcessingEnvironment$DiscoveredProcessors com.sun.tools.javac.processing.JavacProcessingEnvironment.discoveredProcs accessible: 
module jdk.compiler does not "opens com.sun.tools.javac.processing" to unnamed module @3d8512e9

# 翻译

无法使私有字段 com.sun.tools.javac.processing.JavacProcessingEnvironment$DiscoveredProcessors com.sun.tools.javac.processing.JavacProcessingEnvironment.discoveredProcs 可访问：
模块 jdk.compiler 没有将 com.sun.tools.javac.processing 开放给未命名模块 @3d8512e9

问题描述

1. Lombok 版本过旧，不支持 JDK 17，导致的反射访问错误

2. 同时，spring-boot-maven-plugin 版本不匹配，导致插件无法正确处理 JDK 17 的字节码

处理策略

1. 升级 Lombok 版本以适配 JDK 17

<dependency>
    <groupId>org.projectlombokgroupId>
    <artifactId>lombokartifactId>
    <version>1.18.20version>
dependency>

2. 升级 spring-boot-maven-plugin 与 Spring Boot 主版本一致

<groupId>org.springframework.bootgroupId>
<artifactId>spring-boot-maven-pluginartifactId>
<version>3.0.5version>
