你需要在jenkins的运行build的命令配置里增加-X参数，就像下面，来获取更多的报错信息，其他信息看不到。

clean install package -x -Dmaven.test.skip=true -Pprod

我从错误信息里看到了缺少class

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project cmdbunion_eureka: Execution default-compile of goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile failed: A required class was missing while executing org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile: org/codehaus/plexus/compiler/util/scan/InclusionScanException

有可能是这两个文件损坏了

[ERROR] urls[0] = file:/DATA/repo/repository/org/apache/maven/plugins/maven-compiler-plugin/3.8.1/maven-compiler-plugin-3.8.1.jar
[ERROR] urls[1] = file:/DATA/repo/repository/org/codehaus/plexus/plexus-utils/1.1/plexus-utils-1.1.jar

建议你把jenkins服务的目录/DATA/repo/repository/下的关于/org/codehaus/plexus/plexus-utils/1.1/plexus-utils-1.1.jar和org/apache/maven/plugins/maven-compiler-plugin/3.8.1/maven-compiler-plugin-3.8.1.jar删除掉，重新执行jenkins任务，它会重新下载新的依赖。

但是更多信息应该给mvn参数加上-x打开调试信息

另外你设置了两个jdk，可能还跟你的mvn获取的jdk版本有关，查看你写代码时的jdk版本是不是跟maven给出的日志里的jdk版本是兼容的。
