控制台是

编译错误：[信息] -------------------------------------------------- ------------ [错误] 此环境中未提供编译器。也许你正在跑步 在 JRE 而不是 JDK 上？ [错误] 未能执行目标 org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile 项目springBootSecurityJPA-1上的（默认编译）：编译 失败

【问题讨论】：

什么错误？在此处包含错误文本..

【参考方案1】：

错误提示您使用的是 JRE 而不是 JDK。检查您的 JAVA_HOME 变量。
