使用Java17项目后尝试运行Java8项目时出错

Question

我必须处理不同的项目，其中一个是使用Java 8，另一个是Java 17。上周我在使用Java 17，现在我正在尝试将我的配置还原为使用Java 8。

这些是我的配置

$ mvn --version
Apache Maven 3.8.4 (9b656c72d54e5bacbed989b64718c159fe39b537)
Maven home: /usr/local/Cellar/maven/3.8.4/libexec
Java version: 1.8.0_251, vendor: Oracle Corporation, runtime: /Library/Java/JavaVirtualMachines/jdk1.8.0_251.jdk/Contents/Home/jre
Default locale: en_BR, platform encoding: UTF-8
OS name: "mac os x", version: "10.16", arch: "x86_64", family: "mac"
$ java -version
java version "1.8.0_251"
Java(TM) SE Runtime Environment (build 1.8.0_251-b08)
Java HotSpot(TM) 64-Bit Server VM (build 25.251-b08, mixed mode)

我也删除了~/. m2内的所有文件夹。

我在IntelliJ中的配置是：

项目结构

SDK:OpenJDK 1.8

语言级别：SDK默认

项目结构

模块SDK：项目SDK（OpenJDK 1.8）

首选项|构建、执行、部署|编译器| Java编译器

项目字节码：8

首选项|构建、执行、部署|构建工具| Maven |导入

JDK for importer：使用Project SDK

运行/调试配置

JRE:OpenJDK 1.8

我错过什么了吗？为什么会抛出此错误？

问题似乎是Tomcat在Java8上运行时与log4j 2.15不兼容。

请参阅其他应用服务器的相关问题：

• Log4j 2.16.0 java 8

通常此类问题会通过应用服务器更新来修复。如果不可能，请在没有JEP-238的情况下使用log4j库。
