使用sed命令的Jenkinfile ssh问题

Question

我已经写了一个Jenkinsfile，在一个步骤中我被卡住了，那基本上就是部署阶段。在部署阶段，有一个步骤，我必须ssh到一台服务器并运行几个命令。早些时候它工作得很好，但是当我用一些正则表达式添加sed命令时，Jenkins显示语法错误。下面是代码片段。

                steps {
                      sshagent ( credentials: []) {

sh '''
echo "Tag=miqp-server_${BUILD_NUMBER}" > sshenv
echo "target=${DeployTo}" >> sshenv
scp sshenv root@SERVERIP:~/.ssh/environment
ssh -T -o StrictHostKeyChecking=no -l root SERVERIP <<'EOF'

#DEPLOYMENT_NAME="miqp-server-dep"
#CONTAINER_NAME="miqp-server-dev"
#NEW_DOCKER_IMAGE="2xxxxxxxxxx6.dkr.ecr.us-east-1.amazonaws.com/miqp-devops:${Tag}"
RELEASE_NAME=miqp-server-dep

if [ "${target}" = "None" ]
then
  echo "No deployment to K8s"
else

cd /root/kubernetes-ingress/dev/miqp-server-dep/
sed -i "s/^\([[:space:]]*tag:[[:space:]]*\).*/\1$Tag/" values.yaml
helm upgrade -f values.yaml $RELEASE_NAME miqp-server-dep.0.1.0.tgz

#kubectl set image deployment/$DEPLOYMENT_NAME $CONTAINER_NAME=$NEW_DOCKER_IMAGE -n devops-dev
#kubectl rollout status deployment $DEPLOYMENT_NAME -n devops-dev

fi
EOF'''

Jenkins抛出的错误是

WorkflowScript: 156: unexpected char: '\' @ line 156, column 13.
   sed -i "s/^\([[:space:]]*tag:[[:space:]]*\).*/\1$Tag/" values.yaml
               ^

嘿，我已经通过提供转义字符解决了这个问题

sed -i "s/^\([[:space:]]*tag:[[:space:]]*\).*/\1$Tag/" values.yaml 

sed -i "s/^\\([[:space:]]*tag:[[:space:]]*\\).*/\\1$Tag/" values.yaml

谢谢
