Using the sh step on Windows - jenkins

Question

TL;DR I want to use the sh step even though Jenkins is running on Windows. I do not want to use the bat step, unless you can show me how to easily reproduce what I need done using bat
I've been converting some old Jenkins jobs over to 2.x Pipeline script. One of my jobs uses the "Publish over SSH plugin" to:
Send artifacts to a remote server
Exec a set of commands on the remote server
For instance:
I wanted to replicate this in Pipeline Script so I've done the following:
stage('Deploy') {
withCredentials([[$class: 'FileBinding', credentialsId: 'bitbucket-key-file', variable: 'SSHKEY']]) {
sh '''
scp -i "$SSHKEY" dsub.tar.gz tprmbbuild#192.168.220.57:dsubdeploy
scp -i "$SSHKEY" deployDsubUi.sh tprmbbuild#192.168.220.57:dsubdeploy
ssh -i "$SSHKEY" -o StrictHostKeyChecking=no 192.168.220.57 <<- EOF
DEPLOY_DIR=/home/tprmbbuild/dsubdeploy
echo '*** dos2unix using sed'
sed -e 's/\r$//' $DEPLOY_DIR/deployDsubUi.sh > $DEPLOY_DIR/deployDsubUi-new.sh
mv $DEPLOY_DIR/deployDsubUi-new.sh $DEPLOY_DIR/deployDsubUi.sh
chmod 755 $DEPLOY_DIR/deployDsubUi.sh
echo '*** Deploying Dsub UI'
$DEPLOY_DIR/deployDsubUi.sh $DEPLOY_DIR/dsub.tar.gz
EOF'''
}
}
Problem is, I get this stack trace when executing my build:
[Pipeline] sh

Answer 1

Agreed with "it is my belief it is failing to spawn the shell". It is trying to run "E:\Jenkins\tools\Git_2.10.1\usr\bin\sh.exe" (using Windows backslash syntax). Unless we have a shell executable configured (sh.exe) in the mentioned directory, it will fail.
Powershell (or Cmd Shell):
If you are oepn to use batch files, you would have to install/configure 3 binaries (ssh, scp, ssh). Everything else falls in place (I see that you are channeling commands to a remote machine using ssh. I assume that the remote server is linux/unix based).
Alternatives:
You can use cygwin or run linux on virtualbox (or any software that emulates linux on windows). But, running just 3 commands may not be worth the trouble (It will definitely be fruitful if you have plans to convert/write more shell scripts in future).

Answer 2

You can use "bat" instead of "sh" in windows.
Also use 2 backslashes to escape the path string correctly. See example below
node {
currentBuild.result = "SUCCESS"
try {
stage('Checkout'){
checkout scm
}
stage('Convert to Binary RPD'){
bat "D:\\oracle\\Middleware\\user_projects\\domains\\bi\\bitools\\bin\\biserverxmlexec -D .\\RPD -P Gl081Reporting -O .\\GLOBI.rpd"
}
stage('Notify'){
echo 'sending email'
// send to email
emailext (
subject: "SUCCESS: Job '${env.JOB_NAME} [${env.BUILD_NUMBER}]'",
body: """$PROJECT_NAME - Build # $BUILD_NUMBER - $BUILD_STATUS:
Check console output at $BUILD_URL to view the results.""",
to:"girish.lakshmanan#abc.co.uk girish.la#gmail.com"
)
}
}
catch (err) {
currentBuild.result = "FAILURE"
throw err
}
}

Answer 3

You should be able to run the scp.exe from the git installation directly within a batch script.
There is no "here" document for batch as far as I know, but you could just put the script to be run on the server into a separate file.
(Untested)
stage('Deploy') {
withCredentials([[$class: 'FileBinding', credentialsId: 'bitbucket-key-file', variable: 'SSHKEY']]) {
bat '''
E:\\Jenkins\\tools\\Git_2.10.1\\usr\\bin\\scp.exe -i "${SSHKEY}" dsub.tar.gz tprmbbuild#192.168.220.57:dsubdeploy
E:\\Jenkins\\tools\\Git_2.10.1\\usr\\bin\\scp.exe -i "${SSHKEY}" deployDsubUi.sh tprmbbuild#192.168.220.57:dsubdeploy
E:\\Jenkins\\tools\\Git_2.10.1\\usr\\bin\\scp.exe -i "${SSHKEY}" -o StrictHostKeyChecking=no 192.168.220.57 < server_script.sh
}
}
