Escape double quotes and single quotes in Jenkins pipeline script

Question

I have one powershell command inside that both Double quotes and single quotes are present and it's needed for sure in order to make the command execute successfully in dos prompt. I am not sure how to make it escape in pipeline script.

bat "powershell -Command "(Get-Content "${Physical_FolderLoc}\\${Stord_Process_Name}.txt") | ForEach-Object { $_ -replace [RegEx]::Escape('E:\\config'), 'I:\\config' } | Set-Content "${Physical_FolderLoc}\\${Stord_Process_Name}.txt" " "

In the above command you can see the second last " is ending quote for Get Content and last one is for bat command. I tried the above command with triple slash but getting groovy error.

groovy.lang.MissingPropertyException: No such property: _ for class: groovy.lang.Binding
at groovy.lang.Binding.getVariable(Binding.java:63)
at org.jenkinsci.plugins.scriptsecurity.sandbox.groovy.SandboxInterceptor.onGetProperty

Please help me to resolve this.

Answer 1

Change each internal double quoted string, eg:

"${Physical_FolderLoc}\\${Stord_Process_Name}.txt"

to:

('{0}\\{1}.txt' -f $Physical_FolderLoc, $Stord_Process_Name)

Answer 2

I got the exact issue why the command was not escaping. There is a stand alone $ symbol in the powershell command which is also a system character for groovy, so that need to be escaped as well.(The $ character which is after ForEach-Object { ). It's now prefixed with \\, so escaped.

Now the complete command is :

bat "powershell -Command \"(Get-Content ${Physical_FolderLoc}\\${Stord_Process_Name}.txt) | ForEach-Object { \$_ -replace [RegEx]::Escape('E:\\config'), 'I:\\config' } | Set-Content ${Physical_FolderLoc}\\${Stord_Process_Name}.txt\" "

Though no one had tried to help much, but still thanks a lot for the suggestion.
