问题排查:
问题关键提示信息: 报java.lang包没找到，怀疑跟环境变量或Windows jdk路径有关

1.排查java环境变量=> 正常
2.怀疑跟Windows jdk路径相关 => 根因
问题原因
Windows环境Maven compiler插件路径问题
image.png
问题fix:
如下所示的配置很特殊：windows 下使用分号（;）分隔，linux/mac 下使用冒号（:）分隔
修改后重新Maven打包正常，问题修复
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>${maven.compiler.version}</version>
<configuration>
<source>${java.version}</source>
<target>${java.version}</target>
<encoding>UTF-8</encoding>
<!-- 不是maven推荐的方式，只是为了方便管理后台人员频繁开发的jar包 -->
<compilerArguments>
<extdirs>src\main\webapp\WEB-INF\lib</extdirs>
<!-- 这个配置很特殊：windows下使用分号（;）分隔，linux/mac下使用冒号（:）分隔 -->
<bootclasspath>${java.home}/lib/rt.jar:${java.home}/lib/jce.jar</bootclasspath>
