编译插件时：maven抛出错误

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project user-lib: Fatal error compiling: java.lang.IllegalAccessError: class lombok.javac.apt.LombokProcessor (in unnamed module @0x2a9f8d47) cannot access class com.sun.tools.javac.processing.JavacProcessingEnvironment (in module jdk.compiler) because module jdk.compiler does not export com.sun.tools.javac.processing to unnamed module @0x2a9f8d47 -> [Help 1]

在 Java 11 版本上一切正常。 现在我正在尝试升级到 Java 版本 17。立即出现了这样的错误。 我不明白这个错误与什么有关。龙目岛和它有什么关系？

【参考方案1】：

问题出在lombok版本中 https://github.com/projectlombok/lombok/issues/2681 安装了lombok 1.8.22版本，错误消失了。
