In Groovy variable\/expression substitution inside of strings (interpolation) only works with certain types of string literal syntax. Single quote syntax ('content'<\/code>) is not one of them. However, if you replace the outer single quotes with double quotes (\"content\"<\/code>) then you should get the interpolation effect you are looking for:<\/p>\n

def sDescription = \"foo\"\ndef sedCommand = \"sed -i 's\/Description=\\\"[^\\\"]*\\\"\/Description=\\\"$sDescription\\\"\/g\\'  package.appxmanifest\" as String\n<\/code><\/pre>\n
This should give you the string that contains the command you wish to run. Please note how I changed the special character escaping (\\<\/code>) within the string to reflect the change in string delimiters.<\/p>\n
Aside:<\/strong> As noted by @tim_yates, Why would you want to invoke a separate ad hoc<\/em> process to do this substitution when Groovy contains excellent XML manipulation facilities built into the language?<\/p>\n<\/p><\/div>\n
