求助，我在远程到Jenkins的机器后，以root用户运行ant dump是没问题的，可是Jenkins运行ant dump就报错。
下面是我的build.xml
<?xml version="1.0" encoding="UTF-8"?>
<project name="vmuser" xmlns:jacoco="antlib:org.jacoco.ant" default="jacoco">
<!--Jacoco的安装路径-->
<property name="jacocoantPath" value="/root/tools/jacoco-0.8.5/lib/jacocoant.jar"/>
<!--最终生成.exec文件的路径，Jacoco就是根据这个文件生成最终的报告的-->
<property name="jacocoexecPath" value="/var/lib/jenkins/workspace/vmUserCodeCoverage/result/jacoco.exec"/>
<!--生成覆盖率报告的路径，直接放在tomct下面，外界直接访问-->
<property name="reportfolderPath" value="/var/lib/jenkins/workspace/vmUserCodeCoverage/report"/>
<!--远程tomcat服务的ip地址-->
<property name="server_ip" value="127.0.0.0"/>
<!--前面配置的远程tomcat服务打开的端口，要跟上面配置的一样-->
<!--这个端口有别于tomcat的端口，相当于是嵌在tomcat里的监视器-->
<property name="server_port" value="8229"/>

<!--跑的是class，标注的是源码？-->

我检查了所有依赖的文件夹权限，全都改成了777 ，Jenkins的运行身份也提升到了root，都不行。
