一、问题描述
错误：
springframework\buildSrc\src\main\java\org\springframework\build\CheckstyleConventions.java:68: 错误: 找不到符号
List<String> buildFolders = List.of("bin", "build", "out");
^符号：方法
of(java.lang.String,java.lang.String,java.lang.String)位置：接口
java.util.List
源码错误文件如下

}二、解决方案
Gradle JVM版本过低，需要在Java 8版本以上，建议Java 17，因为官方Spring版本用的就是Java 17
将 Settings 里面的 gradle JVM 配置设置为 Java 17 即可
